## About the role

You will own the solid rocket motor for our two interceptor platforms. That covers everything from motor requirements and grain design to the case, nozzle, igniter, static fire, and flight. You’ll report to the CTO. The motor has to deliver the impulse and thrust profile the interceptor needs while fitting the size limits of existing launchers and surviving the full range of storage and flight environments. You’ll work directly with the founders and with the mechanical, GNC, aerodynamics, and avionics engineers. Found on 1752vc Careers, the job board for startup and VC roles.

- B.S. in Aerospace, Mechanical, or Chemical Engineering, or a related field. M.S. preferred
- 5+ years of solid rocket motor development experience
- Has taken at least one solid rocket motor from concept through static fire, including grain design, nozzle, and igniter integration
- Strong grasp of internal ballistics, combustion, heat transfer, and pressure vessel design
- Hands-on test experience, including static fire operations, instrumentation, and data analysis
- Working knowledge of safe handling and storage of energetic materials
