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 • Translate P&IDs into integrated engine CAD; define all fluid, structural and instrumentation interfaces. • Design flanged, threaded and welded interfaces: bolted-joint preload and torque-tension, cryogenic seals, weld-joint preparation and inspection access. • Model the engine and route feed, purge, pressurisation and instrumentation lines and interconnections, supports and vibration. • Create and maintain top-down CAD models of the integrated engine and sub-assemblies; run tolerance stack-ups. • Write phase-wise assembly instructions and travellers with torque sequences, inspection points, cleanliness and FOD controls. • Manage the drafting/CAD team: set modelling and drawing standards, check and release drawings. • Own configuration management: part numbering, revision control, EBOM/MBOM, ECR/ECO change control, NCR and rework dispositions, as-built traceability. • Specify assembly tooling, handling fixtures and engine-to-stand adapters. • Support shop-floor builds, hot-fire campaigns and post-test activities. BASIC QUALIFICATION • B.E./B.Tech/M.E./M.Tech in Mechanical or Aerospace Engineering. • Min. 5+ years in assembly and integration of propulsion hardware. • Hands-on work experience with pump-fed engine cycles (gas-generator, staged-combustion, expander or electric-pump). • Experience with cryogenic propulsion hardware (LOX, LCH4 or LH2). • Advanced large-assembly CAD/PLM: Siemens NX/Teamcenter, CATIA/3DEXPERIENCE or Creo/Windchill. • GD&T per ASME Y14.5 and release of production drawings. PREFERRED SKILLS & EXPERIENCE • Bolted-joint design to NASA-STD-5020; AN/MS flared fittings; metallic and spring-energised cryogenic seals. • Weld design and callouts to AWS D17.1; orbital GTAW, EB welding and brazing. • Oxygen-service cleaning and compatibility (ASTM G93, NASA-STD-6001, IEST-STD-CC1246). • DFMA for machined, welded and L-PBF additive (e.g. Inconel 718) parts. • Instrumentation-port integration (pressure, temperature, vibration) and mass-properties/CG tracking. • First-article inspection and aerospace quality-system experience. • Has led draughtsmen or a small design team WHAT WE OFFER • Salary: ₹16–36 LPA fixed CTC, variable 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.
