Key Takeaways

  • Air Liquide uses Workday as its global ATS at airliquidehr.wd3.myworkdayjobs.com/AirLiquideExternalCareer; apply there rather than through aggregators whenever possible.
  • The Group is French in origin and French-leaning at Paris HQ, but English is the working language for Electronics, Global Markets and Technology, and most regional Gas and Services hubs.
  • Expect three to five interview stages for most experienced roles, with a strong preference for precise, technically grounded answers over polished generalities.
  • Safety, long-cycle customer thinking, and international mobility are the three cultural filters that run through every business line.
  • The two strategic themes most worth referencing in interviews are low-carbon hydrogen (Normand'Hy, 200 MW PEM electrolyzer in Port-Jérôme, start-up end of 2026) and semiconductor gases (over 250 million euros of 2025 European investment, Dresden ASUs and hydrogen units).
  • French stage, alternance, VIE, and the ALLEX graduate program are the main entry channels for early-career candidates in France.
  • Tailor resume language to the exact business line vocabulary; Workday recruiter searches use those tokens as filters.

About Air Liquide

Air Liquide S.A. is the world co-leader in industrial and medical gases, alongside Linde, and the largest industrial gas company in Europe. Founded in Paris in 1902, the Group is headquartered at 75 Quai d'Orsay in the 7th arrondissement of Paris and is listed on Euronext Paris under ticker AI.PA as a founding constituent of the CAC 40 index. The company reported record 2025 revenue of 26.94 billion euros and employs roughly 65,000 to 67,000 people serving customers and patients across 59 countries. François Jackow has been Chief Executive Officer since June 2022 and is executing the Group's ADVANCE strategic plan, which unites financial performance with decarbonization commitments and now runs through 2025 with a successor plan expected to follow. Air Liquide's operations are organized into four business segments. Gas and Services is by far the largest, encompassing Large Industries (on-site production and pipeline gas supply to refineries, steel, chemicals and power customers), Industrial Merchant (bulk and packaged gases to general industry and manufacturing), Electronics (ultra-high-purity gases and advanced materials for semiconductor fabs, a business with more than 4,000 dedicated employees globally and over 2.5 billion euros in annual revenue), and Healthcare (medical oxygen, home healthcare, and hygiene products for hospitals and patients). Global Markets and Technology handles large engineered projects, syngas, biomethane and hydrogen infrastructure. Engineering and Construction designs and builds the Group's own production units and sells technology to third parties. A separate Innovation activity holds hydrogen energy mobility and a small but strategically visible space and cryogenics portfolio linked to launcher programs. Two themes dominate the company's current trajectory. The first is hydrogen. Air Liquide is building Normand'Hy in Port-Jérôme, a 200-megawatt proton exchange membrane electrolyzer expected to start up by the end of 2026 to supply TotalEnergies under a long-term contract, a flagship for renewable hydrogen in France. The US Inflation Reduction Act has also unlocked material capital investment in American low-carbon hydrogen and electronics gas infrastructure. The second theme is electronics. In July 2025 the Group announced more than 250 million euros of investment to support the European semiconductor industry, including three new air separation units and two hydrogen production units for the emerging Dresden ecosystem in Germany, reinforcing its position as the default industrial gas partner for fabs alongside existing deep relationships in Taiwan, Korea, the United States and Singapore. Helium remains a watch item; softer sales in EMEA and China have pressured that sub-segment through 2025. For candidates, Air Liquide is a traditional, capital-intensive industrial company with the cadence and risk posture that implies. Safety is genuinely non-negotiable, not a slogan. Careers are long, frequently international, and often move across business lines. The culture is French in origin and remains French-leaning at the Paris headquarters, but the Group operates in a truly global mode, and English is the working language across the Gas and Services regional hubs, Electronics, and most project and engineering work.

Application Process

  1. 1
    Start at the public careers hub at airliquide

    Start at the public careers hub at airliquide.com/careers to read the employer value proposition, then use the 'Job offers' link which redirects to the Workday careers portal at airliquidehr.wd3.myworkdayjobs.com/AirLiquideExternalCareer. This single portal hosts listings for every country and business line, including Gas and Services regional hubs, Electronics, Healthcare, Engineering and Construction, and corporate roles at the Paris headquarters.

  2. 2
    Use the Workday filters rather than the search box

    Use the Workday filters rather than the search box. Country, business line, job category and 'worker sub-type' (permanent, fixed-term, internship, apprenticeship, VIE) are the highest-signal facets. Roles tied to French entities will frequently list the description in French; international and Electronics roles default to English. For Paris HQ roles, expect either language and sometimes both in the same posting.

  3. 3
    Create a Workday candidate profile the first time you apply

    Create a Workday candidate profile the first time you apply. Air Liquide uses a standard Workday resume parser that auto-populates the Experience and Education sections. Review every parsed field, because the parser frequently misreads French and non-Latin dates, degree names and employer names; the parsed text is what recruiters screen first, not your PDF.

  4. 4
    Tailor the resume file you upload to the specific job family

    Tailor the resume file you upload to the specific job family. A process engineer, a plant operations manager, a B2B commercial role for the chemicals segment, a semiconductor fab account manager, a corporate finance analyst in Paris and a home-healthcare nurse coordinator each screen on different keywords. Mirror the language of the posting itself, not generic industry terminology.

  5. 5
    For students and new graduates, apply directly through the dedicated students an

    For students and new graduates, apply directly through the dedicated students and graduates section of the careers site, and consider the ALLEX (Air Liquide Leading EXcellence) graduate program, the French VIE international volunteer track, and the substantial stage and alternance pipeline advertised on the Workday portal, on engagement-jeunes.com, JobTeaser and Welcome to the Jungle. French stage and alternance roles are the single largest entry channel into the Group in France.

  6. 6
    Expect a multi-round interview process

    Expect a multi-round interview process. Candidates widely report an initial HR screen followed by two to five subsequent interviews depending on seniority. A graduate process is typically two to three conversations; experienced and leadership roles commonly run four or five, including panel interviews with business line leadership and cross-functional stakeholders.

  7. 7
    Prepare for technical evaluation

    Prepare for technical evaluation. Engineering, operations and R&D roles often include a case or problem-solving exercise, and Electronics roles usually probe deeply on gas purity, abatement, and fab operations. Commercial roles include a selling or account strategy case. Some corporate and finance roles use assessment tests administered through Workday or a third-party provider.

  8. 8
    Offers are formal and usually staged

    Offers are formal and usually staged. Expect an initial verbal offer from the hiring manager or recruiter, followed by a written offer, reference checks and, for regulated roles in Healthcare and certain operational functions, medical and safety qualification checks. Start dates for stage, alternance and VIE roles often align with academic calendars.

Resume Tips for Air Liquide

recommended

Lead with quantified impact, not job titles

Lead with quantified impact, not job titles. Air Liquide recruiters screen for measurable production, safety, cost, yield, and commercial outcomes. Numbers expressed in SI units, kilotonnes, megawatts, percentage uptime, and euros are expected; convert US or imperial units where possible.

recommended

Put safety outcomes in the top third of the resume for any operational, engineer

Put safety outcomes in the top third of the resume for any operational, engineering or site-based role. Lost-time injury rates, process safety incidents avoided, audit results, and specific HSE certifications (ISO 45001, IOSH, NEBOSH, CSE in France) are read as primary qualifications, not nice-to-haves.

recommended

Use the exact terminology of the business line you are targeting

Use the exact terminology of the business line you are targeting. For Large Industries use 'ASU', 'air separation unit', 'pipeline', 'on-site', 'oxygen', 'nitrogen', 'argon', 'hydrogen'. For Electronics use 'ultra-high-purity', 'UHP', 'bulk specialty gases', 'abatement', 'sub-fab', 'wafer fab', 'Dresden', 'Taiwan', 'fab ramp'. For Healthcare use 'medical oxygen', 'home healthcare', 'patient adherence', 'CPAP', 'oxygen therapy', 'hygiene'.

recommended

Name the ATS vocabulary from the posting: 'Industrial Merchant', 'Large Industri

Name the ATS vocabulary from the posting: 'Industrial Merchant', 'Large Industries', 'Global Markets and Technology', 'Engineering and Construction', 'Gas and Services', and region codes such as EMEA, AMER, APAC. Recruiters filter candidates by these exact tokens inside Workday.

recommended

Language matters

Language matters. If the job is at the Paris HQ or a French operational site, submit the resume in French even if the posting is bilingual; include a second English version in the same upload if the role has international scope. For international roles outside France, English is sufficient and expected.

recommended

For engineers, list specific technical software and methods: Aspen Plus, HYSYS,

For engineers, list specific technical software and methods: Aspen Plus, HYSYS, HTRI, AutoCAD, PI System, ISA-95 and ISA-88 frameworks, HAZOP, LOPA, SIL, PHA, Six Sigma green or black belt. Cryogenic, rotating equipment, and compressor experience are signals for Large Industries; clean-room and specialty gas handling experience are signals for Electronics.

recommended

For commercial roles, quantify portfolio size (annual revenue managed, number of

For commercial roles, quantify portfolio size (annual revenue managed, number of accounts, territory), contract complexity (long-term take-or-pay, indexed pricing), and customer verticals (refining, chemicals, steel, food and beverage, electronics, healthcare). Multi-year B2B relationship management is valued above transactional sales.

recommended

For corporate and Paris HQ roles, emphasize cross-border experience, second and

For corporate and Paris HQ roles, emphasize cross-border experience, second and third languages beyond French and English, and exposure to French GAAP, IFRS, SOX-equivalent French internal control, and AMF or ESMA reporting requirements for finance and legal roles.

recommended

Keep formatting austere and Workday-friendly

Keep formatting austere and Workday-friendly. Single column, standard fonts, no graphics, no tables for dates, no text inside images. Save as PDF with selectable text. Two pages is the expected norm in Europe; one page is acceptable for early-career candidates and often preferred at US sites.

recommended

Explain international mobility explicitly

Explain international mobility explicitly. Air Liquide careers often include multi-country rotations; if you are open to relocation, state target regions and work authorization status. If you hold EU, US or other work authorizations, put that on the resume because it removes a gating question during screening.

ATS System: Workday

Air Liquide uses Workday Recruiting as its global applicant tracking system. The public career site lives at airliquidehr.wd3.myworkdayjobs.com/AirLiquideExternalCareer and covers every country and business line. A separate French-localized surface is available at the same domain with the /fr-FR path prefix. Workday is a structured-data ATS: every field on your candidate profile is searchable by recruiters, and resume parsing auto-fills those fields from the document you upload. The quality of that parse is what determines whether you appear in recruiter searches inside the system, so investing time in the profile itself matters as much as the attached resume.

  • Upload a PDF with selectable text. Scanned resumes and image-based PDFs produce empty Experience and Education sections in Workday and effectively hide you from recruiter searches.
  • After the auto-parse step, manually review every Experience, Education, Language, and Skill entry. Fix misread dates, employer names with accents or non-Latin characters, and degree titles. French diplomas (Ingénieur, Master spécialisé, BTS, DUT) and non-French equivalents often need hand correction.
  • Populate the Skills section with explicit keywords from the job description. Workday recruiters search this field with filters; a skill listed only inside a bullet point is less discoverable than one tagged in the Skills section.
  • Select the correct 'Worker Sub-Type' when applying. Applying for a permanent role when the posting is a stage, alternance or VIE will cause the application to be filtered out.
  • Set language preferences in your profile to match the role. French language ability, CEFR level, and any additional languages (German, Spanish, Mandarin, Japanese, Korean) should appear in the Languages section, not only in the resume body.
  • Use the Job Alerts feature. Air Liquide posts large volumes of stage, alternance, VIE and graduate roles on predictable academic cycles, and alert emails often surface roles before they are promoted elsewhere.
  • Do not apply to more than a few roles in parallel. Workday records every application, and recruiters can see your full application history across the Group; a scatter-gun pattern reads as a lack of direction.

Interview Culture

Air Liquide interviews are structured, formal, and technically substantive.

The tone is European-professional: polite, measured, and more reserved than a typical US tech interview, with a clear preference for precise answers over confident improvisation. For roles at the Paris headquarters and at French operational sites, expect an initial screen in French with a recruiter, followed by deeper conversations that may switch to English if the role is international in scope. For Electronics, Global Markets and Technology, Engineering and Construction, and the regional Gas and Services hubs outside France, English is the default working language throughout. A typical process has three to five stages. First is a 30 to 45 minute recruiter screen covering motivation, career history, language ability, mobility, and compensation expectations. Second is a hiring manager interview that goes deep on the functional fit: an ASU operations role will probe cryogenic safety, rotating equipment reliability, and plant economics; a B2B commercial role will probe pipeline management, account planning, and contract structures; an Electronics field role will probe wafer fab customer dynamics, gas purity specifications and on-site problem resolution. Third, candidates frequently meet cross-functional peers, including a safety or HSE representative for operational roles and a finance business partner for commercial roles. Fourth, senior or strategic roles include a conversation with the business line leader or a member of the regional executive committee. A final interview with HR closes the loop on package and start date. Case exercises are common. Engineering candidates should expect a technical problem grounded in a real operational scenario: a purity excursion, a compressor trip, a heat exchanger fouling case, a capacity debottlenecking study. Commercial candidates should expect an account or territory case where they must construct a value proposition, calculate margin, and present a plan. Finance and corporate roles at Paris HQ sometimes use structured assessment tests. Candidates consistently report that answers grounded in explicit data, trade-off reasoning, and acknowledgement of safety or regulatory constraints score higher than clever but hand-waved answers. Cultural signals matter. The Group values long tenure, international mobility, and multi-business-line careers; interviewers will probe whether you can commit to that arc. They prefer candidates who ask precise questions about the role and who demonstrate awareness of the Group's businesses beyond their immediate target function. Knowing that Gas and Services contains Large Industries, Industrial Merchant, Electronics and Healthcare, and being able to articulate which one the role sits inside and how it connects to the others, is a baseline expectation. Familiarity with the ADVANCE plan, the Normand'Hy hydrogen project, and the semiconductor investment thesis in Dresden and the US signals that you have done the real reading. Practicalities: French interviews often begin and end with handshakes or a formal greeting; remote interviews retain the formal register. Dress is business formal for Paris HQ and senior commercial roles, business casual for site-based operational roles and for Electronics in Asian and US sites. Response times can be slower than US peers, particularly in August and around December; a two to three week gap between stages is normal and does not signal disinterest.

What Air Liquide Looks For

  • Safety-first operating reflex. Every candidate, whether engineer, commercial, corporate or healthcare, is evaluated on whether they treat safety as a primary decision input rather than a constraint to be optimized around.
  • Depth in a defined technical or commercial craft, not generalist breadth. Air Liquide invests in long-tenured specialists: process and cryogenic engineers, rotating equipment experts, fab account managers, home-healthcare clinicians, hydrogen infrastructure project managers.
  • International mobility and cross-cultural fluency. The Group moves people across countries and business lines, and candidates who signal genuine willingness to relocate, including between continents, have materially better internal career prospects.
  • Language capability beyond English. French is a strong plus at the Paris HQ and a baseline expectation for many French-based roles. German, Spanish, Mandarin, Japanese, Korean, and Arabic materially expand the roles you are eligible for across the Gas and Services regional hubs.
  • Customer-centric commercial thinking, even for non-sales roles. Air Liquide's business model is long-cycle B2B with deeply embedded customer relationships, and candidates who can articulate how their work serves a specific customer segment score higher.
  • Decarbonization and energy transition fluency for 2025 and 2026 hires. Familiarity with low-carbon hydrogen, electrolyzers, biogas, carbon capture, and the policy frameworks behind them (EU Renewable Energy Directive, US IRA) is increasingly a differentiator across the Group, not only in Innovation.
  • Engineering and operational rigor. Process safety, ISO standards, HAZOP and LOPA methods, Six Sigma discipline, and P&ID fluency are expected of engineering hires, and recruiters screen resumes for them explicitly.
  • Long-term orientation. Air Liquide's stock and internal narrative both emphasize durable, compounding performance rather than short bursts of growth. Candidates who tell career stories grounded in multi-year commitments, promotions, and progressive responsibility fit the pattern.

Frequently Asked Questions

What ATS does Air Liquide use, and where is the real careers portal?
Air Liquide uses Workday. The public portal is airliquidehr.wd3.myworkdayjobs.com/AirLiquideExternalCareer, and airliquide.com/careers redirects applicants to that Workday site. A French-localized surface is available at the same domain with the /fr-FR path. All countries, business lines and job categories, including stages, alternance and VIE roles, are posted there.
Do I need to speak French to work at Air Liquide?
It depends on the role. For positions at the Paris headquarters on Quai d'Orsay and at French operational sites, French is expected or strongly preferred, and interviews are typically conducted in French with some English. For Electronics, regional Gas and Services hubs in the Americas and Asia-Pacific, and most Global Markets and Technology and Engineering and Construction roles, English is the working language, and French is not required. The Group genuinely operates in multiple languages, so stating your CEFR level and any additional languages on your resume is valuable.
What are the best entry points for students and new graduates?
In France, the primary channels are stage (internship) and alternance (work-study apprenticeship) roles posted on Workday and aggregated on engagement-jeunes.com, JobTeaser and Welcome to the Jungle. The ALLEX (Air Liquide Leading EXcellence) graduate program is a flagship accelerated development track for high-potential fresh graduates, and the VIE international volunteer program places young French and EU nationals in Air Liquide entities abroad for 12 to 24 months. Internationally, local graduate programs exist in several large country hubs and are advertised through the same Workday portal.
How many interview rounds should I expect?
Candidates consistently report two to five stages depending on seniority. A graduate-level process is typically two to three interviews: HR screen, hiring manager, and sometimes a panel or skip-level. Experienced and leadership roles commonly run four or five stages including a technical or case exercise, cross-functional interviewers, and a senior business line leader. A two to three week gap between stages is normal in France, particularly in August and around the December holidays.
What kind of technical assessment should an engineering candidate expect?
Most engineering interviews include a case problem grounded in real operations. For Large Industries and Gas and Services engineering roles, this might be a purity excursion, a compressor or turbine trip, a heat exchanger fouling scenario, or a capacity debottlenecking study, and interviewers expect explicit reference to process safety frameworks such as HAZOP, LOPA and SIL. For Electronics, expect questions on ultra-high-purity gas specifications, sub-fab equipment, abatement, and wafer fab customer operations. Software, automation and data roles may include a coding or systems design exercise, though Air Liquide is not a software-first company and the bar is calibrated to industrial context.
What does the Group actually do besides oxygen tanks in hospitals?
Air Liquide's Gas and Services segment is the largest, covering Large Industries (on-site and pipeline gas supply to refineries, steel, chemicals and power plants), Industrial Merchant (bulk and packaged gases to general industry), Electronics (ultra-high-purity gases to semiconductor fabs, a 2.5-billion-euro-plus business in 2024), and Healthcare (medical oxygen, home healthcare and hygiene). Beyond that, Global Markets and Technology runs large engineered projects, syngas, biomethane and hydrogen infrastructure; Engineering and Construction designs and builds the Group's own plants and sells technology to third parties; and the Innovation activity includes hydrogen energy mobility and a small strategic space and cryogenics portfolio.
Is Air Liquide investing in hydrogen, and does that change what they hire for?
Yes, substantially. The Normand'Hy project in Port-Jérôme is a 200-megawatt proton exchange membrane electrolyzer expected to start up by the end of 2026, supplying TotalEnergies under a long-term contract, and is the Group's European flagship for renewable hydrogen. The US Inflation Reduction Act has also unlocked material low-carbon hydrogen and electronics gas investment in the United States. Hiring impact shows up across project management, electrochemistry, power purchase and commercial contracting, electrolyzer operations, safety engineering for high-pressure hydrogen, and policy-facing roles. Candidates fluent in electrolyzer technology, green power contracting, and EU or US hydrogen subsidy frameworks are in particular demand.
How strong is Air Liquide's semiconductor business, and how do I get hired into it?
Electronics is one of the Group's fastest-growing businesses, generating over 2.5 billion euros in 2024 revenue with more than 4,000 dedicated employees worldwide. In July 2025, Air Liquide announced more than 250 million euros of European investment including three new air separation units and two hydrogen production units to serve the emerging Dresden semiconductor ecosystem in Germany, reinforcing its position alongside existing deep footprints in Taiwan, Korea, Singapore and the United States. Hiring targets fab engineers, process engineers, bulk specialty gas operations staff, and account managers with prior experience at a semiconductor manufacturer, a fab equipment supplier, or a competitor industrial gas company. Posting locations cluster around existing and new fab clusters.
What should I put on my resume to maximize ATS match rate?
Mirror the exact vocabulary of the job posting, especially the business line name (Large Industries, Industrial Merchant, Electronics, Healthcare, Global Markets and Technology, Engineering and Construction), region codes (EMEA, AMER, APAC), and technical tokens (ASU, UHP, HAZOP, LOPA, SIL, Aspen Plus, PI System, ISO 45001, etc.). Populate Workday's Skills and Languages sections explicitly, not only the resume body. Quantify outcomes in SI units and euros. Keep formatting austere and use a selectable-text PDF so Workday's parser extracts every field cleanly.
Does Air Liquide relocate employees, and how much international mobility is expected?
Yes. Air Liquide has a long-standing practice of moving employees across countries and business lines over the course of a career, and the Group views international mobility as a primary development lever rather than an occasional perk. For many technical, commercial and leadership tracks, candidates who indicate genuine openness to relocate, including between continents, have materially better internal career prospects. VIE and ALLEX programs are explicit international-mobility entry points for early-career candidates.
