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.
KEY RESPONSIBILITIES
1. Jig, fixture & weld tooling fabrication
• Fabricate and assemble jigs, drilling fixtures and weld fixtures for propellant tanks, domes, inter-stage structures, motor cases, thrust structures and brackets.
• Build weld fixtures for aerospace alloys (aluminium 2219/2195/6061, titanium, Inconel, stainless steel), including backing bars, purge fixtures and chill bars.
• Support friction stir welding (FSW), orbital TIG and electron-beam welding setups with rigid, repeatable clamping.
• Plan the build: material cutting, machining, welding, stress relief, surface treatment and assembly sequence.
• Fit locators, clamps, pins and bushings to drawing tolerances and datums; flag manufacturability issues to the design team.
2. Stage assembly & integration stands
• Build, install and commission stage assembly stands, horizontal and vertical integration fixtures, rotation and turnover fixtures, and access platforms.
• Set foundations, anchoring and levelling; align stands to the bay datum and to each other for stage-to-stage and payload integration.
• Align interface rings and mating features with laser tracker or optical tooling to the required concentricity and perpendicularity.
• Prepare fixtures for cleanroom use: cleanable finishes, no shedding coatings, cleanroom-compatible wheels and covers.
• Support integration campaigns at the factory and at the launch site as needed.
3. Handling, lifting & transport fixtures
• Fabricate lifting beams, spreader bars, stage handling dollies, transport cradles, shipping containers and launch-site transport fixtures.
• Follow qualified welding procedures (WPS/PQR) and NDT requirements for all critical and lifting hardware.
• Arrange proof-load testing, SWL/WLL marking, certification and test records before release.
• Build transport fixtures that protect hardware from shock and vibration, with shock and humidity monitoring provisions.
• Comply with space-industry ground support equipment and lifting standards [e.g. NASA-STD-8719.9, ECSS-E-ST-10-03, ASME B30.20 / BTH-1, IS 3177 / Factories Act – confirm for site].
4. Fixture build, trial & validation
• Manage fixture builds in-house and with suppliers: work orders, material certificates, schedule and inspection.
• Inspect fixtures with CMM, laser tracker and other metrology; record as-built data.
• Run first-article trials with production using dummy or pathfinder hardware before flight hardware is loaded.
• Validate repeatability, part fit, weld quality, cycle time and safety; release fixtures with signed acceptance records.
5. Calibration, cleanliness & tooling upkeep
• Run calibration and periodic verification schedules for fixtures, gauges, torque tools and lifting equipment.
• Maintain FOD (foreign object debris) control and cleanliness of tooling used near flight hardware.
• Provide ESD protection and grounding on fixtures used for avionics and electrical integration.
• Plan preventive maintenance, repair wear or damage, and implement approved modifications with revision records.
• Investigate tooling-related non-conformances and lead root-cause and corrective actions (8D, 5-Why) through the MRB process.
6. Tooling register, traceability & storage
• Maintain the tooling register: tool ID, drawing revision, location, condition, calibration, proof-load and inspection due dates.
• Keep full traceability: material certificates, weld records, NDT and proof-load reports per tool.
• Tag and label all tooling with ID and status (in use, quarantined, calibration due, flight-hardware approved).
• Organise safe, clean storage with covers, preservation and corrosion protection & report tooling readiness ahead of each build.
REQUIRED SKILLS & QUALIFICATIONS
• Bachelor’s degree or diploma in Mechanical, Manufacturing, Production or Aerospace Engineering, or a trade background with equivalent experience.
• 8+ years building jigs, fixtures, weld tooling or precision fabricated structures, preferably in aerospace, space or defence.
• Strong reading of engineering drawings, GD&T (ASME Y14.5 or ISO GPS) and weld symbols.
• Hands-on fabrication and welding knowledge, including aerospace alloys and distortion control on thin-walled structures.
• Working knowledge of machining and standard tooling components (clamps, locators, bushings).
• Precision measurement: laser tracker, CMM, optical alignment, precision levels.
• Knowledge of lifting equipment safety, rigging for high-value hardware and proof load testing.
• Understanding of FOD control, cleanroom discipline and ESD precautions around flight hardware.
• Disciplined documentation: build and inspection records, traceability, calibration logs and the tooling register.
PREFERRED SKILLS
• Experience with launch vehicles, satellites, solid or liquid propulsion hardware, or ISRO / DRDO / HAL programmes and their suppliers.
• Experience with friction stir welding, electron-beam welding or orbital welding fixtures.
• Welding or inspection certification (AWS CWI, ISO 9606, ISO 9712 / ASNT NDT Level II). nd willingness to travel for campaigns.
• Familiarity with AS9100, ECSS or NASA workmanship standards, first-article inspection (AS9102) and MRB / non-conformance processes.
• Laser tracker operation (Leica, FARO, API) for large-volume alignment of stages.
• Launch-site support experience and willingness to travel for campaigns.
• Ability to view and measure in CAD models (SolidWorks, CATIA or NX viewer) – no design work required.
