The Astrobase Propulsion team is looking for experienced and passionate professionals who can own the vehicle's stage fluid and propulsion systems from design to flight.

Key Responsibilities

- Design ownership of pre-combustion devices, continuous improvement
- Design the oxidiser-rich and fuel-rich preburners for FFSC engines: injector elements, chamber, igniter ports and hot-gas ducts to the turbines.
- Manage thermal, structural and stability analyses through start, steady and shutdown transients; set margins and life to NASA-STD-5012.
- Build CAD models and release drawings with GD&T; for printed, machined and welded preburner parts.
- Create and own process for manufacturing, assembly and testing
- Plan water-flow, spray and igniter tests and component hot-fire, analyze test data and continuously improve designs.
- Define acceptance tests: proof, leak, flow check; Conduct ECR/ECO, NCR dispositions.
- Documentation, change management and hardware acceptance.

DESIRED QUALIFICATION
- B.E./B.Tech/M.E./M.Tech in Mechanical or Aerospace Engineering.
- Min. 5+ years designing and testing liquid rocket combustion devices.
- Hands-on work on preburners or gas generators for pump-fed engines, taken through hot-fire.
- Experience with cryogenic propulsion hardware (LOX, LCH4 or LH2).
- Injector analysis: element pressure drop, atomisation, mixing and c* efficiency.
- Advanced CAD/PLM: Siemens NX/Teamcenter, CATIA/3DEXPERIENCE or Creo/Windchill

Preferred Qualification

- Oxidiser-rich or full-flow staged-combustion hardware,



through component or engine test.
- Reacting-flow CFD (Star-CCM+ or Fluent) and FEA (Ansys Mechanical or Abaqus).
- Torch or spark igniter design and start-sequence work with engine systems.
- Stability tools and high-frequency pressure data analysis.
- Design for additive manufacturing.
