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 • Build and update engine and sub-assembly models in the top-down layout set by the integration engineer: brackets, clamps, stand adapters and their space claims. • Route fluid lines and instrumentation harnesses in 3D, holding bend radii, clearances, clamp spacing, thermal-contraction allowance and spanner access at every joint. • Prepare installation, tube and harness drawings with GD&T, bend tables (XYZ or LRA) for the tube shop, and pin-out lists for every connector. • Keep the build P&ID and wiring diagrams matched to the model, with each line, valve, sensor and connector tagged once. • Draft stage-wise build work instructions with exploded views, torque values, inspection holds and cleanliness steps for engineer review. • Raise change requests, carry approved changes into models, drawings and BOMs, and record which engine serial numbers each change applies to. • Maintain part numbers, revision letters, the EBOM and the released-document list in PLM; prepare drawing packages for check and release. BASIC QUALIFICATION • Diploma in Mechanical Engineering. • Min. 10+ years in CAD modelling and drafting of aerospace, defence or space hardware. • Large-assembly modelling with tube and harness routing in Siemens NX/Teamcenter, CATIA/3DEXPERIENCE or Creo/Windchill. • Production drawings with GD&T per ASME Y14.5, including tube and harness drawings. • Reads P&IDs, wiring diagrams and engineering change documents. • Revision control and change workflows in a PLM system. PREFERRED SKILLS & EXPERIENCE • Routing of high-pressure or cryogenic lines with AN/MS flared or flareless fittings. • Harness routing with bundling, clamping and connector backshell clearances. • Configuration management to SAE EIA-649C; drawing revisions per ASME Y14.35. • Work instructions built from 3D exploded views or 3D PDFs. • Has worked on liquid rocket engine or launch vehicle integration hardware. • Has trained junior draughtsmen. WHAT WE OFFER • Salary: ₹12–20 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.
