Job summary

Astrobase Space Technologies in Bengaluru is seeking an experienced propulsion engineer to own the vehicle's stage liquid and propulsion systems from design to flight. You will conceptualise and implement cryogenic systems for two-stage methalox propulsion, create P&IDs and CAD models, and drive hardware realization and tests.

The role demands hands-on experience with cryogenic fluids, stage hardware, and strong Python/CAD skills, with 4+ years in propulsion or fluid systems.

Qualifications

• B.E./B.Tech/M.E./M.Tech/M.S. in Mechanical or Aerospace Engineering.
• Min. 4+ years designing, building and testing propulsion or fluid systems hardware.
• Hands on experience with stage, engine or test-stand fluid systems hardware.
• Experience with cryogenic fluid systems and hardware (LOX, LCH4, LH2, LN2).
• Working experience with Python, CAD tools and clear engineering writing.

Responsibilities

• Own the liquid/cryogenic systems of the lower and upper methalox stages: propellant feed, fill-drain, propellant intake & management devices, slosh-control systems, pogo suppression systems, and umbilical connections.
• Conceptualise, design and analyse these systems: line sizing, pressure-drop budgets, tank and engine conditioning, chill-down, surge, insulation, slosh, and other cryogenic systems requirements.
• Create and manage P&IDs and CAD models for these systems and their hardware, keep them updated with every change, and generate drawings for manufacturing and integration.
• Define stage interfaces with engine, structures, avionics and ground systems in ICDs, including umbilical plates and quick disconnects.
• Drive and coordinate hardware realisation, and support stage integration and assembly.
• Own acceptance of hardware: proof, leak and cleanliness checks, valve functional tests and non-conformance dispositions.
• Plan and run testing and qualification: cold-flow, cryogenic flow, propellant loading tests and static fires; prepare evidence for flight-clearance reviews.
• Analyse test data in Python and apply the learning to improve the systems.
• Define processes, servicing procedures, loading sequences and countdown chronology; plan test-stand and launch-pad operations.
• Write and maintain test plans and design, test and anomaly reports.
