ABOUT ASTROBASE SPACE TECHNOLOGIES
Astrobase is a pioneering spacetech startup founded by prominent Senior ISRO scientists and IIT Bombay alumni with over 20 years of experience in designing, manufacturing, testing and flying advanced Cryogenic Launch Vehicles. Driven by a vision to make India a Space tech powerhouse, we are developing innovative launch vehicles that will transform space exploration. At Astrobase, you’ll be part of a team creating history in the Indian space industry. Our goal is to become the first private space company from India to land on the moon economically. Our Propulsion team is looking for experienced and passionate professionals who have designed and hot-fired preburners or gas generators.

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.

DESIRED 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 QUALIFICATION

• 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: ₹24–36 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.
