ATS Resume Optimization for Aerospace Engineers

Recruiters typically search title variants (Aerospace Engineer, Aeronautical Engineer, GNC Engineer, Structures Engineer, Systems Engineer) combined with tools and clearance terms. The most common tool keywords in 2026 postings are CATIA V5, Siemens NX, ANSYS, NASTRAN, MATLAB, Simulink, and IBM DOORS, alongside skills like FEA, CFD, and Model-Based Systems Engineering (MBSE). For defense roles, clearance terms — Secret, Top Secret, TS/SCI — and export-control terms like ITAR and U.S. Person are often the first filters applied. Mirror the exact phrasing from the job posting, including both acronyms and spelled-out forms.

Put an active clearance in your resume header or summary — for defense and government contractor roles it is often the first thing a recruiter checks or filters on. Use the exact standard phrasing: 'Active Secret Clearance,' 'Top Secret,' or 'TS/SCI,' plus the adjudication or investigation date if recent. If you are clearance-eligible but not cleared, say 'eligible to obtain a Secret clearance.' Never disclose classified program details; a phrase like 'ITAR-controlled program' or 'classified DoD program' conveys relevance safely. If a posting requires U.S. Person status under ITAR, state your eligibility plainly.

The credentials recruiters recognize include the PE (Professional Engineer) license, which is less common in aerospace than civil engineering but valued for signature authority, and INCOSE's systems engineering certifications: ASEP (Associate Systems Engineering Professional) for early-career engineers and CSEP (Certified Systems Engineering Professional), which requires roughly five years of systems engineering experience. Also list working knowledge of standards by exact name — AS9100 for aerospace quality management, DO-178C for airborne software, DO-254 for airborne electronic hardware, and relevant MIL-STD references such as MIL-STD-810. Standards knowledge often functions as a keyword filter even when no certification exists.

Yes. ATS keyword matching is often literal, so use the exact designation from the posting: DO-178C (not 'DO-178' alone if the posting specifies the C revision), AS9100, DO-254, MIL-STD-810, or MIL-STD-882. The same rule applies to tools — write 'CATIA V5' if the posting does, and 'MATLAB/Simulink' as separate recognizable terms. Include both the acronym and expansion for less universal terms, for example 'Model-Based Systems Engineering (MBSE)' and 'Guidance, Navigation and Control (GNC),' so you match whichever form the recruiter searches.

Defense demand remains strong on the back of record U.S. defense budgets, with hiring concentrated in missile defense, munitions, hypersonics, and unmanned systems — so cleared candidates with MIL-STD and ITAR program experience are heavily sought. The space sector continues hiring for GNC, propulsion, and structures roles on launch vehicles and satellite constellations. eVTOL and Advanced Air Mobility programs are moving toward certification, raising demand for FAA certification and DO-178C experience. Across all segments, Model-Based Systems Engineering skills — SysML, Cameo, DOORS — appear increasingly in postings, so digital engineering experience is worth surfacing prominently.

Keep a master resume and adjust the top third per application. For defense roles, lead with clearance status, ITAR program experience, and MIL-STD references, and emphasize systems engineering vocabulary like requirements management in DOORS and verification and validation. For commercial aviation or eVTOL roles, lead with FAA regulatory experience, DO-178C or AS9100 familiarity, and certification program contributions. The tool stack — CATIA or NX, ANSYS or NASTRAN, MATLAB/Simulink — is transferable, so keep it consistent, but reorder your bullet points so the first bullet under each job matches the target posting's primary requirement.
