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 performance
  • Data integrity as it relates to operational use and certification
  • Interfaces and information flow between subsystems
• Reviews 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 evidence
  • Supporting certification documentation and compliance matrices
  • Assisting in verification and validation (V&V) assessment reviews
  • Supporting test planning activities from a systems and requirements perspective
• Contributes 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 summaries
  • Test plans, procedures, and reports
  • Certification and compliance support documentation
• Ensures documentation is technically accurate, clearly written, traceable to requirements, and suitable for government review.

Systems Engineering Support

• Participates in systems engineering activities across the system lifecycle, including:
• • Requirements review and decomposition
  • Design and interface evaluation support
  • Integration and verification support from a systems perspective
• Assists in identifying technical and certification risks related to avionics system behavior, interfaces, and data handling.

Team and IPT Support

• Works within Integrated Product Teams (IPTs) to support multi‑platform avionics engineering efforts.
• Coordinates with:
• • Senior systems and certification engineers
  • Government program offices and stakeholders
  • Software developers, integrators, and test organizations
• May provide informal guidance to junior team members or support task execution under supervision.

Required:

• Knowledge of software engineering fundamentals, including data structures and logical design
• Proficiency in high-order programming languages
