• 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.
