- Define and manage software requirements, decomposition, and traceability (DO-178C)
- Lead software architecture and design reviews across engineering teams
- Support multi-core processors, deterministic scheduling, and fault-tolerant systems
- Drive integration and testing strategies (SIL, HIL, and hardware testing)
- Build and improve automated testing and static analysis frameworks (VectorCAST, Parasoft, etc.)
- Support CI/CD pipelines in a regulated aerospace environment
- Collaborate with systems, controls, hardware, and safety teams
- Promote reusable software platforms across multiple programs
What You Bring
- 8+ years of experience in embedded software development
- Strong experience with FADEC or engine control systems
- Proficiency in C for real-time embedded systems
- Experience with DO-178C or similar safety-critical standards
- Background in software architecture or platform-level design
- Experience with RTOS or real-time embedded systems
- Familiarity with Agile and DevOps in regulated environments
- Experience using tools like Git, Bitbucket, Jira
- Bachelor’s degree in Engineering or related field

- Knowledge of SIL / HIL testing environments
- Familiarity with MOSA (Modular Open Systems Architecture)
- Experience generating certification documentation and audit support
- Experience with automated verification, coverage tools, or static analysis
- Exposure to engine control, avionics, or aerospace propulsion systems
