Rocket Engine Assembly & Integration Engineer

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.
  
  

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.
