Quest Defense Systems and Solutions is seeking experienced a Senior Embedded Software Engineer to join to architect and evolve the core software platform supporting Full Authority Digital Engine Control (FADEC) systems. This role focuses on building scalable, reusable, safety-critical embedded software infrastructure that supports multiple engine programs and certification baselines. This is a platform-level engineering role emphasizing real-time determinism, modular architecture, certification alignment, and long-term product sustainability.

Due to the nature of the project all applicants must be US Citizens. This role is remote with a strong preference to be onsite in Endicott, NY.

Responsibilities:

• Architect and maintain reusable FADEC software platform components, including hardware abstraction layers (HAL), middleware, and RTOS integrations.
• Define high-level software requirements, decomposition, and traceability in compliance with DO-178C.
• Lead system and software architecture reviews to ensure alignment with safety, performance, and certification objectives.
• Develop and optimize embedded C software for real-time, mission-critical engine control applications.
• Support multicore processors, deterministic scheduling, and fault-tolerant architectures.
• Drive integration and verification strategies including SIL, HIL, and embedded target testing.
• Establish automated test and static analysis frameworks (e.g., VectorCAST, Parasoft) to support compliance and code coverage objectives.
• Contribute to CI/CD processes within a regulated DevOps environment.
• Collaborate with systems, hardware, controls, and safety engineering teams to ensure robust cross-system integration.
• Promote common software baselines and reusable frameworks across programs.

Required Skills:

• 8+ years of experience with FADEC or engine control systems.
• Strong background in high-level requirements definition and regulated software development (DO-178C or similar).
• Embedded software development experience in C for aerospace or defense applications.
• Experience with system architecture and mission-critical software design.
• Familiarity with Agile Scrum and DevOps practices in regulated environments.
• Experience with configuration management tools (Git, Bitbucket, Jira).
• US Citizenship

Desired Skills:

• 9+ years of engineering experience with a bachelor's degree in engineering or related discipline.
• Experience with RTOS environments and multicore embedded architectures.
• Experience with HIL/SIL testing and embedded systems integration.
• Knowledge of Modular Open Systems Architecture (MOSA) and XML-based interface standards.
• Experience generating certification-ready documentation and supporting audits.
• Experience with automated verification, static analysis, and code coverage tools.
• Onsite in Endicott, NY
