About this role
Greenfield Engineering, a Saalex Company is seeking an Avionics Systems Engineer to support the analysis, documentation, and certification of avionics systems associated with navigation and airspace integration capabilities. This role focuses on systems engineering, certification support, and technical documentation, rather than hands‑on software development or testing.
The Avionics Systems Engineer supports engineering and certification efforts across U.S. Navy, Marine Corps, Coast Guard, and Foreign Military Sales (FMS) aviation platforms, with an emphasis on Performance Based Navigation (PBN), RNAV/RNP, and CNS/ATM capabilities. The incumbent works under the guidance of a senior systems or lead engineer and contributes to the review and assessment of avionics systems, requirements, and engineering artifacts supporting airworthiness and certification activities.
Position Type: Full-Time
Salary: $122k-$165k annually (depending on experience) Work Location: Full-time onsite with some telework (see onsite requirements below)
**On-site Requirements: This position is full-time onsite at Patuxent River, MD and may be eligible for reoccurring telework, but will require an onsite work greater than or equal to 85% of the work week”
Essential Functions:
Avionics Systems & Certification Analysis
Supports the evaluation of avionics systems and associated software artifacts to assess: System behavior and functional performanceData integrity as it relates to operational use and certificationInterfaces and information flow between subsystemsReviews engineering artifacts, system outputs, and analysis products to identify discrepancies, risks, or areas requiring clarification.
Engineering Support to Certification Activities
Assists in certification and compliance efforts for systems pursuing RNAV, RNP, and related CNS/ATM approvals by: Reviewing requirements, design documentation, and compliance evidenceSupporting certification documentation and compliance matricesAssisting in verification and validation (V&V) assessment reviewsSupporting test planning activities from a systems and requirements perspectiveContributes to engineering and airworthiness assessments under the direction of senior engineers.
Technical Documentation & Engineering Artifacts
Develops and supports technical documentation, including: Engineering assessments and analysis summariesTest plans, procedures, and reportsCertification and compliance support documentationEnsures documentation is technically accurate, clearly written, traceable to requirements, and suitable for government review.
Systems Engineering Support
