Process Design Engineer ATS Keywords: Complete List for 2026

The resumes that consistently land interviews for process design engineer roles aren't the ones with the most impressive project lists — they're the ones where candidates describe how they optimized a process, not just that they did. Specifically, the candidates who pair simulation software proficiency (like Aspen HYSYS or CHEMCAD) with quantified throughput improvements almost always make it past both the ATS and the hiring manager's 10-second scan [13].

An estimated 75% of resumes are rejected by applicant tracking systems before a human ever reads them [11]. For process design engineers, where technical vocabulary is dense and role-specific, the gap between a well-keyworded resume and a generic one is even wider.

Key Takeaways

• ATS systems parse process design engineer resumes for specific technical terms — generic engineering language like "problem-solving" won't trigger the right filters without accompanying hard skill keywords like "P&ID development" or "mass and energy balance" [11].
• Tier your keywords by importance: process simulation software, PFD/P&ID creation, and scale-up experience are non-negotiable; Six Sigma and regulatory compliance keywords add competitive edge [4][5].
• Action verbs matter more than you think — "Optimized," "Scaled," and "Commissioned" signal hands-on design experience in ways that "Managed" and "Assisted" never will.
• Keyword placement across multiple resume sections (summary, skills, experience bullets) increases your match score more than concentrating them in a single skills block [12].
• Roles in this SOC category (17-2199) have a median salary of $117,750 [1], and with only 2.1% projected growth through 2034 [8], standing out in a tight applicant pool is essential.

Why Do ATS Keywords Matter for Process Design Engineer Resumes?

Applicant tracking systems work by scanning your resume for keywords and phrases that match the job description, then scoring your application against other candidates [11]. For process design engineers, this creates a specific challenge: the role sits at the intersection of chemical engineering, mechanical systems, and industrial operations, which means ATS algorithms are looking for a precise blend of technical terms that generic engineering resumes often miss.

When a recruiter at a chemical manufacturer or EPC firm posts a process design engineer opening, their ATS is typically configured to prioritize candidates whose resumes contain terms pulled directly from the job posting — things like "process flow diagram," "heat exchanger design," "HAZOP," or specific simulation platforms [12]. If your resume uses "flow chart" instead of "process flow diagram" or "safety review" instead of "HAZOP," the system may not recognize the match.

The BLS reports approximately 9,300 annual openings across the broader engineering specialties category (SOC 17-2199) [8], but each of those openings can attract hundreds of applicants. With 75% of resumes filtered out before human review [11], the math is stark: if 200 people apply, roughly 50 resumes reach a recruiter's desk. The difference between the 50th resume that makes it through and the 51st that doesn't often comes down to keyword alignment, not qualifications.

Process design engineer resumes also face a parsing challenge unique to technical roles. ATS systems can misread complex formatting — multi-column layouts, tables for skills matrices, or embedded images of process diagrams. When the system can't parse your content correctly, even perfectly chosen keywords become invisible [11]. Clean formatting paired with strategic keyword placement is the foundation everything else builds on.

What Are the Must-Have Hard Skill Keywords for Process Design Engineers?

Not all keywords carry equal weight. Based on analysis of current job postings for process design engineers [4][5], here's how to tier your technical keywords:

Essential (Include All of These)

1. Process Design — This is your core identifier. Use it in your title, summary, and at least two experience bullets.
2. Process Flow Diagrams (PFDs) — Specify that you've created, reviewed, or revised PFDs. Include the acronym and the full term.
3. Piping and Instrumentation Diagrams (P&IDs) — Same approach. ATS systems may scan for either the acronym or the spelled-out version [12].
4. Process Simulation — The umbrella term. Always pair it with the specific software you've used (see below).
5. Mass and Energy Balance — Fundamental to the role. Embed it in a bullet describing a specific calculation or optimization outcome.
6. Heat Exchanger Design — One of the most frequently listed requirements in process design postings [4].
7. Equipment Sizing and Selection — Use this exact phrase; "equipment specification" is a close variant worth including too.
8. Scale-Up — Critical for candidates moving from pilot to production-scale work. Quantify the scale factor when possible.

Important (Include 4-5 of These)

9. HAZOP (Hazard and Operability Study) — Demonstrates safety and risk assessment competency. Mention whether you led or participated in HAZOP reviews.
10. Process Optimization — Pair with a metric: "Reduced energy consumption by 18% through process optimization of the distillation column."
11. Unit Operations — Distillation, absorption, extraction, filtration — name the specific operations you've designed.
12. Thermodynamics — Particularly relevant for roles in petrochemical, refining, or energy sectors.
13. Process Safety Management (PSM) — Regulatory keyword that signals awareness of OSHA 29 CFR 1910.119 requirements.
14. Capital Cost Estimation — Shows you understand the business side of design, not just the technical side.
15. Batch and Continuous Process Design — Specify which type(s) you have experience with; many postings call out one or both [5].

Nice-to-Have (Include Where Relevant)

16. Computational Fluid Dynamics (CFD) — Increasingly requested for roles involving reactor or mixing vessel design.
17. Statistical Process Control (SPC) — Bridges process design with quality engineering.
18. Lean Manufacturing — Relevant when your designs interface with production operations.
19. Design Basis Documentation — Shows you can define and communicate design parameters to stakeholders.
20. Front-End Engineering Design (FEED) — Particularly valuable for EPC and consulting roles.

When placing these keywords, mirror the exact language from the job description wherever possible. If the posting says "process flow diagram," don't substitute "process schematic" [12].

What Soft Skill Keywords Should Process Design Engineers Include?

ATS systems increasingly scan for soft skills, but listing "team player" in a skills section does nothing for your score or your credibility [12]. The key is to embed soft skill keywords within accomplishment statements that prove the skill.

Here are 10 soft skills that appear frequently in process design engineer job descriptions [4][5], with examples of how to demonstrate each:

1. Cross-Functional Collaboration — "Collaborated with mechanical, electrical, and instrumentation teams to deliver integrated P&IDs for a $40M facility expansion."
2. Technical Communication — "Authored 15+ design basis documents and presented process design reviews to senior leadership and client stakeholders."
3. Analytical Thinking — "Analyzed pilot plant data to identify a 12% yield loss attributable to heat exchanger fouling, then redesigned the cooling loop."
4. Project Management — "Managed the process design deliverables for three concurrent projects, each on schedule and within budget."
5. Attention to Detail — "Conducted line-by-line P&ID reviews that identified 23 specification errors before construction phase."
6. Problem-Solving — "Resolved recurring pressure drop issues in the reactor feed system by redesigning the valve configuration and piping layout."
7. Mentoring / Leadership — "Mentored two junior engineers through their first HAZOP facilitation, reducing review cycle time by 20%."
8. Client-Facing Communication — "Led weekly design review meetings with client engineering teams across three time zones."
9. Adaptability — "Pivoted a brownfield design from batch to continuous processing mid-project after feasibility analysis revealed a 30% cost advantage."
10. Decision-Making Under Uncertainty — "Selected equipment vendors based on incomplete performance data during fast-track project execution, with zero rework required post-commissioning."

Notice that every example includes a specific context and, where possible, a number. That's what transforms a soft skill keyword from filler into evidence.

What Action Verbs Work Best for Process Design Engineer Resumes?

Generic verbs like "Responsible for" and "Assisted with" tell an ATS — and a recruiter — almost nothing about what you actually did. These 18 action verbs align directly with process design engineer responsibilities [6] and signal hands-on technical contribution:

1. Designed — "Designed a three-stage distillation system that increased product purity from 95% to 99.5%."
2. Optimized — "Optimized reactor operating conditions, reducing raw material consumption by 14%."
3. Simulated — "Simulated the entire ethylene cracking process in Aspen HYSYS to validate design assumptions."
4. Scaled — "Scaled a pharmaceutical API process from 10L bench to 2,000L production reactor."
5. Commissioned — "Commissioned a new solvent recovery unit, achieving steady-state operation within 72 hours."
6. Specified — "Specified heat exchangers, pumps, and control valves for a greenfield chemical plant."
7. Developed — "Developed PFDs and P&IDs for a 50,000 BPD crude oil processing facility."
8. Evaluated — "Evaluated three competing reactor technologies and recommended the fluidized bed configuration based on NPV analysis."
9. Calculated — "Calculated mass and energy balances for a multi-product batch facility."
10. Modeled — "Modeled two-phase flow behavior using OLGA to size subsea pipeline systems."
11. Validated — "Validated process design against API and ASME standards prior to detailed engineering."
12. Facilitated — "Facilitated HAZOP reviews for 12 process nodes across two operating units."
13. Integrated — "Integrated waste heat recovery into the plant steam system, saving $1.2M annually."
14. Troubleshot — "Troubleshot a recurring column flooding issue and implemented a tray redesign that eliminated downtime."
15. Automated — "Automated batch recipe sequencing using DeltaV, reducing cycle time by 22%."
16. Standardized — "Standardized design templates for equipment datasheets across four regional offices."
17. Reduced — "Reduced wastewater generation by 35% through closed-loop process redesign."
18. Delivered — "Delivered all process engineering deliverables for a $120M project two weeks ahead of schedule."

Start every experience bullet with one of these verbs. Avoid starting with "Responsible for" — it's passive, vague, and wastes valuable keyword real estate.

What Industry and Tool Keywords Do Process Design Engineers Need?

ATS systems don't just scan for skills — they scan for the specific tools, standards, and methodologies that define your working environment [12]. Missing these keywords can cost you a match even when you have the experience.

Process Simulation Software

• Aspen HYSYS and Aspen Plus (Aspen Technology suite — list both if proficient)
• CHEMCAD
• PRO/II (Schneider Electric / AVEVA)
• SuperPro Designer (common in pharmaceutical and biotech process design)
• COMSOL Multiphysics (for CFD and multiphysics modeling)

Design and Drafting Tools

• AutoCAD and AutoCAD P&ID
• SmartPlant P&ID (Intergraph/Hexagon)
• COADE / CAESAR II (pipe stress analysis)
• Microsoft Excel with VBA (still the workhorse for quick calculations — don't overlook it)

Industry Standards and Frameworks

• API (American Petroleum Institute) standards
• ASME (American Society of Mechanical Engineers) codes
• OSHA PSM (Process Safety Management)
• ISO 9001 / ISO 14001 (quality and environmental management)
• Six Sigma (Green Belt or Black Belt certification)
• NFPA standards (fire protection, relevant for facility design)

Certifications

• PE (Professional Engineer) license — the single most impactful credential for this role [7]
• Six Sigma Green Belt / Black Belt
• PMP (Project Management Professional) — valuable for lead or senior roles
• Certified Process Safety Professional — niche but powerful for PSM-heavy environments

Industry Verticals

If you have experience in a specific sector, name it: oil and gas, petrochemical, pharmaceutical, food and beverage, water treatment, specialty chemicals, or semiconductor manufacturing. Many ATS filters include industry-specific terms [4][5].

How Should Process Design Engineers Use Keywords Without Stuffing?

Keyword stuffing — cramming every possible term into your resume regardless of context — backfires in two ways: sophisticated ATS systems can flag unnatural keyword density, and any recruiter who reads past the ATS will immediately notice [11]. Here's how to distribute keywords naturally across your resume:

Professional Summary (3-4 Lines)

Front-load your highest-priority keywords here. Example: "Process Design Engineer with 8 years of experience in petrochemical facility design, specializing in process simulation (Aspen HYSYS, PRO/II), P&ID development, and equipment sizing for greenfield and brownfield projects."

That single summary hits at least six high-value keywords without reading like a list.

Skills Section (10-15 Keywords)

Use this section for exact-match terms that might not fit naturally into sentences: software names, certifications, and technical abbreviations. Format as a simple comma-separated list or a clean single-column layout that ATS systems parse reliably [11].

Experience Bullets (2-3 Keywords Per Bullet)

Each bullet should contain one action verb, one technical keyword, and one measurable outcome. Example: "Simulated the amine gas treating process in Aspen HYSYS, identifying a design modification that reduced solvent circulation rate by 18%."

Education and Certifications

Include your degree field exactly as it appears on your diploma (e.g., "B.S. in Chemical Engineering") and list certifications with their full names and issuing bodies.

A Practical Test

Read your resume out loud. If any sentence sounds like a keyword list rather than a description of work you actually did, rewrite it. The goal is a resume where every keyword earns its place inside a meaningful statement [12].

Key Takeaways

Process design engineer roles command a median salary of $117,750 [1], but with modest 2.1% growth projected through 2034 [8], competition for openings is real. Your resume needs to clear the ATS gate before your experience can speak for itself.

Focus on three priorities: (1) include the essential hard skill keywords — process simulation, PFDs, P&IDs, mass and energy balance, equipment sizing — using exact terminology from the job posting; (2) demonstrate soft skills through quantified accomplishments rather than listing them; and (3) distribute keywords across your summary, skills section, and experience bullets so the ATS picks them up and the recruiter finds them credible.

If building a keyword-optimized resume from scratch feels overwhelming, Resume Geni's tools can help you match your resume to specific job descriptions and identify keyword gaps before you hit submit.

Frequently Asked Questions

How many keywords should be on a process design engineer resume?

Aim for 25-35 unique, relevant keywords distributed across your resume. This typically includes 15-20 hard skills, 5-8 soft skills embedded in accomplishments, and 5-10 tool and certification names. The exact number should be driven by the job description — match as many of its specific terms as your experience honestly supports [12].

Should I use the acronym or the full term for technical keywords?

Use both. Write "Piping and Instrumentation Diagrams (P&IDs)" on first mention, then use the acronym afterward. ATS systems may scan for either form, and including both maximizes your match rate [11].

Do ATS systems read PDF resumes?

Most modern ATS platforms can parse PDFs, but some older systems still struggle with them. Unless the job posting specifically requests PDF, submit a .docx file to be safe. Avoid PDFs created from scanned images — these are essentially invisible to ATS parsers [11].

How do I optimize my resume for a process design engineer role in a different industry?

Study the job description carefully and adjust your industry-specific terminology. A process design engineer moving from oil and gas to pharmaceuticals should emphasize transferable keywords like "batch process design," "scale-up," and "GMP compliance" while de-emphasizing sector-specific terms like "upstream processing" or "refinery operations" [4][5].

Is a PE license important for ATS matching?

A PE license is one of the strongest differentiators for engineering roles. If you hold one, include "PE" or "Professional Engineer" in your name line, certifications section, and summary. Many ATS filters specifically screen for this credential [7].

Should I tailor my resume for every application?

Yes — or at minimum, for every distinct type of role. A resume optimized for a process design engineer position at a pharmaceutical company should emphasize different keywords than one targeting a petrochemical EPC firm. Tailoring your top 5-10 keywords to each job description significantly improves your ATS match score [12].

What's the biggest ATS mistake process design engineers make?

Relying on a single "Technical Skills" section to carry all their keywords. ATS algorithms often weight keywords found in experience bullet points more heavily than those in a standalone skills list, because contextual usage signals genuine proficiency rather than keyword stuffing [11][12]. Spread your keywords across every section of your resume.
