About the role
- If you're driven by hard problems, energized by rapid innovation, and ready to make an impact on next-generation flight systems, you belong here.
Responsibilities
- Own the technical design and performance of solid rocket motor systems and supporting propulsion subsystems across multiple concurrent programs, from concept through qualification and production
- Lead internal ballistics, structural, and thermal analysis of motor cases, nozzles, propellant grains, igniters, and ignition safety components
- Drive static fire test campaigns and ground test infrastructure by defining test plans, instrumentation, and acceptance criteria, and own root-cause investigation when anomalies occur
- Partner with manufacturing and supply chain to design for producibility and scale - Zone 5 builds in quantity, not just for demonstration
- Develop and maintain technical roadmaps for propulsion product lines, including commonality and cost-reduction strategy across programs
- help build the test and design processes that don't yet exist
- Maintain rigorous documentation, safety, and regulatory compliance for energetics and propulsion systems (handling, transport, range safety)
- Mentor and grow propulsion engineers as the team scales under you; help build the test and design processes that don't yet exist
Requirements
- 8+ years of experience in propulsion system design, analysis, or test.
- Strong experience with solid rocket motor design, including internal ballistics, propellant/grain design, motor case, and nozzle design.
- Experience standing up or running static fire/hot fire test campaigns, including instrumentation, data reduction, and anomaly investigation.
- B.S. in Aerospace Engineering, Mechanical Engineering, or equivalent.
- Demonstrated ownership of propulsion systems from concept through flight test or production, not analysis in isolation.
Skills
- Familiarization with energetics handling, transport, and range safety requirements.
- Programming or scripting experience (e.g., MATLAB, Python, or similar) for modeling and data analysis.
- Strong troubleshooting skills in complex propulsion test environments.
Company info
- Represent propulsion technical status to customers, government stakeholders, and leadership
- Represent propulsion technical status to customers, government stakeholders, and leadership; be the face of the subsystem on your programs
