About the job Senior Guidance Systems Engineer
Senior Guidance Systems EngineerWe are seeking a Senior Guidance Engineer to develop guidance solutions for Castelion's long-range hypersonic strike vehicles. This role is critical in shaping the flight performance of our hypersonic systems from concept through flight tests and operational deployment. You will work hands-on with multidisciplinary engineering teams to design, analyze, characterize, and validate guidance algorithms in a rapid hardware-driven environment.
Responsibilities- Lead the design and optimization of hypersonic flight vehicle guidance methods to maximize performance, stability, and maneuverability in atmospheric and space environments
- Conduct trajectory and flight simulations to evaluate guidance system performance, identify improvement opportunities, and validate design decisions
- Analyze and enhance the inertial and active guidance of Castelion's long-range hypersonic systems, ensuring robust performance under variable environmental conditions
- Work closely with teams in avionics, seeker, flight software, and GNC to ensure seamless vehicle integration
- Help define and execute test plans for subscale and full-scale flight tests, translating results into system-level design improvements
- Mentor and guide junior engineers in best practices
- Partner closely with program leadership to make technical trades aligned with mission success
Basic Qualifications- Bachelor's, Master's, or PhD in Aerospace Engineering or related field
- 3+ years of experience in guidance system design, analysis, and validation for high-speed vehicles (missiles, rockets, hypersonic glide vehicles, or maneuvering re-entry systems)
- Demonstrated ability to field guidance systems for DoD or similar programs
- Strong background in trajectory/flight simulation (3DOF and 6DOF) and real-time trajectory generation/optimization methods
- Experience with onboard trajectory generation approaches
- Familiarity with the application of AI/deep learning to trajectory optimization
- Proficiency in flight/trajectory analysis tools such as TAOS, POST, or equivalent
- Strong problem-solving mindset, thriving in a fast-paced, hardware-rich, high flight cadence environment
