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

• Plan and execute lower/upper-stage integration: build sequences, schedules, readiness reviews and shop-floor coordination.
• Work with design, manufacturing and quality teams to make feed, pressurisation, purge, vent/relief, fill/drain and pneumatic systems easy to assemble, inspect, test and integrate.
• Design fluid interfaces, line supports, component mountings, handling fixtures and integration tooling; define engine-to-stage fluid interfaces with the Propulsion team.
• Create and maintain top-level CAD of the complete lower/upper stages, with accurate BoMs and test-stand, facility and GSE/umbilical interfaces; generate assembly drawings for manufacturing and integration.
• Write assembly, inspection and test procedures: torque sequences, cleanliness and FOD controls, leak checks, proof tests, valve functional checks and health checks.
• Oversee stage integration and testing, from cold-flow and cryogenic proof tests to static fires; review assembly & integration checks and assess system performance against requirements.
• Generate and maintain assembly P&IDs; assembly, health-check and test documents; NCRs and dispositions; and as-built traceability records.
• Track BoM availability and kitting status for flight hardware; flag shortages and long-lead items to supply chain and planning.

DESIRED QUALIFICATION

• B.E./B.Tech/M.E./M.Tech in Mechanical or Aerospace Engineering.
• Min. 4+ years in assembly, integration and test of launch vehicle stage or propulsion fluid systems.
• Hands-on work experience integrating high-pressure gas and cryogenic fluid hardware (LOX, LCH4, LN2 or LH2): tubing, valves, regulators, seals and pressure vessels.
• Reading and authoring P&IDs; GD&T and release of production drawings.
• Test-data reduction and review in Python or MATLAB.

PREFERRED QUALIFICATION
• Prior work on similar stage hardware and test campaigns: feed and pressurisation systems, cryogenic tanks and insulated lines, umbilicals/quick disconnects and GSE.
• Tube fittings and routing; welded and bolted joints; metallic and spring-energised cryogenic seals.
• Leak checks; propellant-service cleaning and compatibility.
• Advanced large-assembly CAD/PLM and visualisation skills.
• Aerospace quality systems; first-article inspection; BoM and kitting control in PLM.

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.
