About The Position

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.

Requirements

Knowledge of software engineering fundamentals, including data structures and logical design
Proficiency in two or more high-order programming languages (e.g., C, C++, Ada, Java)
Educational exposure to assembly language concepts
Ability to analyze complex technical problems and interpret data outputs
Technical writing skills sufficient to document engineering analyses and findings
Basic understanding of avionics systems or aerospace engineering principles
Experience in software development, data analysis, or systems engineering (academic or professional)
Demonstrated ability to work in a technical team environment
Bachelor of Science (BS) degree in Computer Science, Electrical Engineering, or related discipline required.
Active Secret clearance required. Requirements to obtain a clearance include US Citizenship, security investigation, etc.

Nice To Haves

Experience analyzing software behavior or system-level data flows
Familiarity with data and control coupling concepts
Experience working in team-based engineering environments (e.g., IPTs)
Basic understanding of mission or flight planning systems
Familiarity with systems engineering processes (e.g., SETR)
Exposure to civil or military avionics programs

Responsibilities

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, and interfaces and information flow between subsystems.
Reviews engineering artifacts, system outputs, and analysis products to identify discrepancies, risks, or areas requiring clarification.
Assists in certification and compliance efforts for systems pursuing RNAV, RNP, and related CNS/ATM approvals by reviewing requirements, design documentation, and compliance evidence.
Supports certification documentation and compliance matrices.
Assists in verification and validation (V&V) assessment reviews.
Supports test planning activities from a systems and requirements perspective.
Contributes to engineering and airworthiness assessments under the direction of senior engineers.
Develops and supports technical documentation, including engineering assessments and analysis summaries, test plans, procedures, and reports, and certification and compliance support documentation.
Ensures documentation is technically accurate, clearly written, traceable to requirements, and suitable for government review.
Participates in systems engineering activities across the system lifecycle, including requirements review and decomposition, design and interface evaluation support, and integration and verification support from a systems perspective.
Assists in identifying technical and certification risks related to avionics system behavior, interfaces, and data handling.
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, and software developers, integrators, and test organizations.
May provide informal guidance to junior team members or support task execution under supervision.
