The Modular Interceptor Platform. Backed by Y Combinator.
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.
What they're looking for
- 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

Own motor requirements and design
- Work with GNC and aerodynamics to turn trajectory needs into motor requirements, including total impulse, thrust profile, burn time, and mass.
- Lead the motor architecture and design, including the grain, case, insulation and liner, nozzle, and igniter.
- Design propellant grains and run burnback analysis to shape the thrust curve.
- Model internal ballistics, chamber pressure, heat transfer, and nozzle erosion.
Select materials and suppliers
- Select propellant formulations, insulation, and nozzle materials.
- Lead decisions on whether to buy propellant and components or produce them in-house, and manage motor suppliers.
