ABOUT ASTROBASE SPACE TECHNOLOGIES Astrobase Space Technologies is an early-stage Bengaluru company building a two-stage orbital launch vehicle. Our engine is a LOX–methane full-flow staged-combustion engine. 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. BASIC 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 SKILLS & EXPERIENCE • 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. WHAT WE OFFER • Salary: ₹24–36 LPA fixed CTC, additional pay based on experience and role fitment. • Attractive early-stage stock options (ESOPs). • Group health insurance: employee, spouse, children and parents. • Insurance: term-life and personal-accident cover. • Work environment: Challenging, stimulating, research-driven work solving rocket problems every day with a great team. We have a good time, and unlimited coffee. WHY WORK WITH US? At Astrobase, we believe in the power of human ingenuity and collaboration to push the boundaries of space exploration.
