Key Takeaways
- Diehl is a family-owned, Stiftung-structured German Mittelstand group in Nurnberg with roughly 17,000 employees and four civil divisions (Metering, Metall, Aviation, Controls), plus a separate Defence arm in Ueberlingen.
- Applications for all civil divisions flow through a shared career portal (diehl.com/career) into an Abacus Umantis ATS at career.diehl.com — not Workday, not SuccessFactors.
- German is effectively required for most Germany-based roles (B2 minimum, C1 preferred); English is fine for international project roles at Diehl Aerosystems and Diehl Metering export.
- Tailor to the specific division and Standort — a Laupheim Aviation role and a Nurnberg corporate role are genuinely different cultures despite the shared brand.
- Expect a structured, formal German interview process: HR screen, Fachgespraech, factory tour, sometimes a senior/board round. Ausbildung candidates add an Eignungstest.
- Use the German Lebenslauf format (tabular, reverse-chronological, one to two pages), cite concrete norms (EN 9100, MID, DIN, IEC) and tools (CATIA, SAP, Hydra), and keep the PDF ATS-clean for Umantis parsing.
- Stability, evidence, safety culture and modesty are rewarded; visionary pitches, heavy negotiation and creative CV layouts are not.
- Diehl Defence is a separate application universe with security clearance requirements — do not conflate it with the civil divisions when writing your cover letter.
About Diehl Group
Application Process
-
1
Start on the group career portal at diehl
Start on the group career portal at diehl.com/group/en/career (redirects to new.diehl.com/career/en) and open the Jobs & Application section. The German-language page is stellenboerse at diehl.com/career/de/jobs-bewerbung/stellenboerse, and for most roles it has more listings than the English version because many positions are Germany-only in German.
-
2
Filter by country (Land), site (Standort), division (Gesellschaft) and job famil
Filter by country (Land), site (Standort), division (Gesellschaft) and job family (Funktionsbereich). Pay attention to the division name on the listing: Diehl Metering, Diehl Aviation, Diehl Metall and Diehl Controls each have distinct hiring managers and distinct cultures. A job at Diehl Metering Ansbach is a very different daily life from a job at Diehl Aviation Laupheim, even though they share a career portal.

3
Click through to the job detail page (hosted on diehl
Click through to the job detail page (hosted on diehl.com itself) and read the Aufgaben (tasks), Profil (profile/requirements) and Wir bieten (we offer) sections carefully. German Stellenanzeigen are unusually specific: if they ask for a particular Ausbildung, a specific norm (EN 9100, ISO 9001, IEC 61508), a CAD tool, or a specific language level (for example Deutsch C1), they mean it.

Click Jetzt bewerben (Apply now) or Apply now, which routes you to career
Click Jetzt bewerben (Apply now) or Apply now, which routes you to career.diehl.com — the external Abacus Umantis applicant self-service portal. Create an account with email and a password, or sign in if you already have one. Returning applicants should always reuse the same account; duplicate profiles are a common reason recruiters lose track of candidates.
-
5
Upload your application documents (Bewerbungsunterlagen) in the expected German
Upload your application documents (Bewerbungsunterlagen) in the expected German format: Anschreiben (cover letter, one page), tabellarischer Lebenslauf (chronological CV, one to two pages, no photo is fine but still common), Zeugnisse (school leaving certificate Abitur or equivalent, university transcripts, Arbeitszeugnisse from prior employers, apprenticeship certificates) and relevant certifications. PDF is the universal expected format; file size is typically capped around 5 to 10 MB per document.
-
6
Fill in structured data fields: desired entry date (Eintrittstermin), salary exp
Fill in structured data fields: desired entry date (Eintrittstermin), salary expectation (Gehaltsvorstellung) as a gross annual figure including any 13th month, notice period (Kuendigungsfrist, often three months for tariff roles), willingness to relocate, and, for technical roles, self-rated language levels (Deutsch, Englisch, Franzoesisch). Give a salary number rather than leaving it blank; an empty field signals inexperience with the German market.
-
7
Answer division-specific screening questions, which can include whether you have
Answer division-specific screening questions, which can include whether you have a valid work permit for Germany or the EU, whether you consent to background checks (especially for Aviation roles with airside access or Controls roles handling certified hardware), and whether you are a German or EU citizen for roles that touch dual-use goods or export-controlled technologies.
-
8
Submit and expect a system confirmation email from the Umantis-hosted career
Submit and expect a system confirmation email from the Umantis-hosted career.diehl.com domain within minutes. Add career.diehl.com to your safe senders list; German spam filters frequently misroute applicant tracking emails. You can log back in at any time to track status, withdraw, or apply to additional positions reusing your uploaded documents.

First recruiter screen typically happens within two to four weeks for active rol
First recruiter screen typically happens within two to four weeks for active roles, sometimes faster for Ausbildung (apprenticeship) roles where intake is seasonal. Silence past four weeks is not a good sign for competitive corporate roles but is normal for niche engineering positions where the hiring committee meets less frequently.

Interview stages for professionals are usually: HR phone or Teams screen (30 to 45 minutes, often in German), a technical or functional interview with the hiring manager and a senior specialist (60 to 90 minutes, often on-site at the Standort), and for senior roles a third round with a division head or board-level contact, sometimes including a factory tour (Werksfuehrung). Apprentices go through an Eignungstest (aptitude test), a group exercise and a personal interview.

Offers in Germany are formal written Arbeitsvertraege (employment contracts) del
Offers in Germany are formal written Arbeitsvertraege (employment contracts) delivered by post or secure PDF, not a quick email. Expect a tariff-bound salary (often IG Metall tariff at Aviation, Metering and Metall sites), 30 days of vacation, a 35-hour work week at many production sites, and benefits tied to the collective agreement. Do not push hard for US-style negotiation; instead, ask politely about Einstiegsstufe (entry step) and any Zulagen (allowances) that apply to your role.
Resume Tips for Diehl Group
Default to German (Lebenslauf) for roles based in Germany unless the ad is writt
Default to German (Lebenslauf) for roles based in Germany unless the ad is written in English end-to-end. A German Lebenslauf is tabellarisch (tabular, reverse-chronological), one to two pages, with clearly labeled sections: Persoenliche Daten, Berufserfahrung, Ausbildung, Kenntnisse und Faehigkeiten, Sprachen, Weiterbildung. A photo is optional since 2006 under AGG but still common; if you include one, use a professional Bewerbungsfoto.
Name the specific Diehl division and site in your Anschreiben (cover letter): "f
Name the specific Diehl division and site in your Anschreiben (cover letter): "fuer die Position ... bei Diehl Aviation am Standort Laupheim" reads naturally. A generic "Diehl-Gruppe" cover letter gets flagged as a mass application. Reference the exact Stellen-ID or Referenznummer from the job ad.
Translate industry-relevant norms and frameworks into Diehl's vocabulary
Translate industry-relevant norms and frameworks into Diehl's vocabulary. For Aviation, name EN 9100 / AS 9100, Part 21, Part 145, Nadcap, FAI and Airbus-specific standards like ABD 0100 or ABD 0200 if you know them. For Metering, call out DIN EN 14154 (water meters), MID (Measuring Instruments Directive 2014/32/EU), OIML, LoRaWAN, wM-Bus, DLMS/COSEM. For Metall, mention DIN EN 12166 (copper and copper alloys), ISO 9001, IATF 16949 if you touched automotive connector alloys. For Controls, cite IEC 60730, IEC 61508, UL 60730 and EMC standards EN 55014.
Map your apprenticeship or degree to the German ladder
Map your apprenticeship or degree to the German ladder. "Bachelor of Engineering" is fine; "M.Sc. Elektrotechnik, TU Muenchen" is better; "Industriemechaniker (IHK)" or "Elektroniker fuer Automatisierungstechnik (IHK)" are gold for production roles. International candidates should translate equivalents clearly (for example, "B.Eng. Mechanical Engineering, equivalent to German Dipl.-Ing. (FH)").
State language levels using the CEFR scale (A1 through C2) rather than vague lab
State language levels using the CEFR scale (A1 through C2) rather than vague labels. For non-customer-facing engineering at Nurnberg HQ or German production sites, Deutsch B2 is typically the absolute floor and C1 is preferred. For shop-floor, Ausbildung-track or union-adjacent roles (tariff-bound IG Metall), C1 is often required in practice even if the ad says fliessend. For Diehl Aerosystems international project teams and Diehl Metering export functions, English C1 plus German B2 is often acceptable.
List tooling precisely
List tooling precisely. CAD: CATIA V5/V6 (standard at Aviation), NX, SolidWorks, Creo. PLM: 3DEXPERIENCE, Teamcenter, Windchill. ERP: SAP S/4HANA, SAP ERP ECC, with specific modules (PP, MM, QM, PM, SD). Simulation: ANSYS, Abaqus, MATLAB/Simulink for Metering firmware. MES: Hydra, SAP ME. Quality: SAP QM, Minitab, 8D, FMEA, APQP, PPAP.
For production and Facharbeiter roles, list concrete machines and certifications
For production and Facharbeiter roles, list concrete machines and certifications: CNC-Drehen, CNC-Fraesen, Mazak, DMG MORI, Heidenhain, Siemens 840D, Schweissen (MIG/MAG, WIG, EN ISO 9606), Kranschein, Staplerschein, IHK-Pruefungsteilnahme als Ausbilder. German Facharbeiter CVs that show only job titles get filtered out; show the specific Maschinenpark and the specific Werkstoffe.
Use Arbeitszeugnisse signals correctly
Use Arbeitszeugnisse signals correctly. If you are German, include references to your best Zeugnisnoten ("stets zu unserer vollsten Zufriedenheit") where relevant. If you are international, do not fake this code; instead, provide a Letter of Recommendation in English and explain briefly in your cover letter that your home country uses reference letters rather than Zeugnisse.
Keep the document ATS-parsable for Abacus Umantis: single-column layout, standar
Keep the document ATS-parsable for Abacus Umantis: single-column layout, standard Latin fonts, no text boxes or embedded images for important content, clear section headings, and a normal PDF (not a flattened image). Umantis is competent at German formats but still fails on creative layouts. Save as Nachname_Vorname_Lebenslauf.pdf; recruiters often download into a single candidate folder.
For Werkstudent (working student) and Praktikum (internship) applications, lead
For Werkstudent (working student) and Praktikum (internship) applications, lead with your Hochschule, Fachsemester, Studienrichtung, and expected graduation. Note your Matrikelnummer only if asked; your expected availability in hours per week during term (typically up to 20) and full-time during semester break is the information Diehl HR is scanning for.
ATS System: Abacus Umantis (Haufe Talent Management)
Diehl Group runs all civil-division recruiting through an Abacus Umantis applicant tracking system hosted at career.diehl.com. Abacus Umantis is a Swiss-German talent management platform, now part of the Haufe Group, widely used across the DACH Mittelstand. The public-facing portal is career.diehl.com/SelfService; vacancy URLs follow the pattern career.diehl.com/Vacancies/{job_id}/Application/CheckLogin/{step}, and the underlying HTML explicitly identifies itself as Abacus-Umantis via a meta ATS tag and a globalUmantisParams JavaScript object. Diehl's own web team renders the job listing index on diehl.com itself for SEO, but the moment you click Apply (Jetzt bewerben), you are inside Umantis. The system handles account creation, CV parsing, structured questionnaire answers, referral tracking, Ausbildung intake, and recruiter workflow end-to-end.
- Create one Umantis account on career.diehl.com and reuse it for every application. Duplicate profiles fragment your history and frustrate recruiters.
- Umantis parses German-format PDFs well but struggles with multi-column creative CVs, embedded tables, and text rendered as images. Use a clean single-column layout.
- The system does CV parsing to prefill fields; always review the auto-filled data and correct it manually. Umantis can transpose Nachname/Vorname or miss accents on umlauts.
- Structured fields (Gehaltsvorstellung, Eintrittstermin, Kuendigungsfrist, Sprachen) are searchable by recruiters. Leaving them blank hides you from internal shortlisting.
- Keyword matching is meaningful in the German Mittelstand ATS context: include exact norms, tariff grades, tool names and Ausbildungs-Bezeichnungen as they appear in the Stellenanzeige.
- File size cap is typically 5 to 10 MB per document and 20 MB total. Compress scanned Zeugnisse (300 dpi is enough) and avoid uploading multi-hundred-MB portfolios.
- Use the Speculative/Unsolicited application path (Initiativbewerbung) only when no matching role exists. Recruiters route these separately and they can sit for months.
- Umantis sends status emails from career.diehl.com. Whitelist the domain; German enterprise spam filters (especially corporate Outlook) occasionally misroute them.
- You can withdraw or update your application at any time from the SelfService dashboard. Update your documents before a scheduled interview rather than emailing the recruiter new PDFs.
- The portal is localized (German, English, French, Polish, Chinese, Hungarian, Spanish). Apply in the language of the job ad; mixing languages inside the same application confuses both the parser and the recruiter.
Interview Culture
Diehl interviews follow the formal German Mittelstand script with a strong engineering culture overlay.
What Diehl Group Looks For
- Verified German qualifications. An IHK Ausbildung, a state-recognized Duales Studium, a Bachelor or Master from an accredited German Hochschule, or a clearly translated international equivalent. Diehl trusts the German qualification system and expects documentation.
- Stability and longevity. German Mittelstand companies, especially family-owned foundations like Diehl, prefer candidates who stay. Three-to-five-year tenures read well. Frequent short stints (under 18 months, repeatedly) get questioned directly in the Fachgespraech.
- Division-relevant domain depth. Aviation expects airworthiness and cabin-systems fluency; Metering expects metrology, radio, embedded or utility-software fluency; Metall expects metallurgy, Zerspanung and process fluency; Controls expects power electronics, firmware and functional safety fluency. Generalists need to pick a division and pitch themselves into it.
- Evidence over narrative. Claims are expected to be backed by certificates, Zeugnisse, published norms or concrete deliverables. "I managed a large project" is weak; "I led the EN 9100 requalification of line 3 in Laupheim over eight months, cutting first-pass defect rate from 4.1 percent to 1.6 percent" is the register.
- Language fit for the site. Deutsch B2 to C1 is the default for Germany-based roles; customer-facing and tariff-bound roles often need C1 in practice. English C1 is the default for international engineering project teams at Aerosystems and Metering export.
- Safety and quality culture. Candidates should be able to discuss arbeitssicher, 5S, Gemba, FMEA, 8D, Ishikawa, Poka-Yoke fluently and without irony. Diehl production sites run on these and view them as table stakes, not buzzwords.
- EU work authorization or a realistic path to it. For non-EU candidates, Blue Card eligibility (roughly Bachelor + qualifying salary threshold) and willingness to relocate to a specific Standort (not just "Germany") are significant positive signals.
- Calm, modest communication. Over-polished, over-branded personal presentation is viewed with mild suspicion. Clear, accurate, understated self-description is the expected register across the organisation, top to bottom.
- Willingness to commute or relocate to the actual Standort. Most Diehl production work is not remote-first. Being realistic about living in Nurnberg, Laupheim, Ansbach, Wangen im Allgaeu, Rothenburg, Ueberlingen or Hamburg matters more than candidates from London or San Francisco often realize.
- Integrity and cleanability for regulated work. Aviation suppliers, metering utilities, defence-adjacent electronics and any site handling export-controlled technologies prefer applicants who can pass background checks without surprises. Disclose cleanly when asked; Diehl's recruiters can handle nuance but not concealment.
