Senior Mechanical Design Engineer

Mechanical Design Engineer | 3–5 Years | Pune On-Site | Full-Time | NON-NEGOTIABLE: B.E./B.Tech mandatory About the Role olee.space is hiring a Mechanical Design Engineer to build the structural hardware around our optical payloads enclosures, brackets, gimbal structures, ground-terminal chassis, thermal mounting hardware, and assembly fixtures. You will work alongside senior opto-mechanical and systems engineers on FSOC terminals and quantum-secure communication hardware, owning sub-assemblies from concept to manufacturing handover. This is a high-leverage early-career role for someone who wants their SolidWorks models turning into real, flight-adjacent hardware within months not years.

What You Will Do Design sub-assemblies in SolidWorks terminal enclosures, electronics housings, mounting brackets, baseplates, gimbal/pan-tilt structural components, cable routing fixtures, and ground-station structures. Produce manufacturing-ready 2D drawings with proper GD&T (ASME Y14.5), datums, tolerances, surface finish callouts, and BOMs. Run first-pass FEA static, modal, basic thermal on brackets, mounts, and structural elements, and escalate complex analyses to senior engineers.

Perform tolerance stack-ups to verify fit, alignment, and clearance before release to manufacturing. Select fasteners, bearings, inserts, gaskets, and standard hardware from vendor catalogues; build and maintain a reusable component library in SolidWorks. Coordinate with vendors and the in-house fab team on CNC machining, sheet-metal, 3D printing, and surface treatment (anodising, powder coating, passivation); review first-article samples and resolve manufacturing queries.

Support integration and testing of FSOC sub-systems fixture design, jig fabrication, and hands-on mechanical build. Maintain design documentation part numbers, revision control, BOMs, build procedures, and ECN/ECR records. Learn opto-mechanical fundamentals under the senior team and progressively take on precision-mount and flexure design work.

You Must Have B.E. / B.Tech (mandatory) in Mechanical Engineering, Aerospace Engineering, Production Engineering, or Mechatronics. 2–5 years of post-graduation experience in mechanical design for hardware products aerospace, defence, instrumentation, robotics, or precision machinery preferred. Strong proficiency in SolidWorks part modelling, assemblies, drawings, sheet-metal, weldments, and configurations. Working knowledge of GD&T (ASME Y14.5), tolerance stack-ups, and standard manufacturing processes (CNC milling/turning, sheet-metal, 3D printing).

Familiarity with engineering materials aluminium alloys, stainless steel, plastics and the ability to select them on strength, weight, machinability, and cost. A hands-on attitude comfortable on the shop floor, fluent with hand tools, and willing to debug hardware physically. Nice to Have Internship or project experience with space, defence, optics, or precision-instrumentation hardware.

Exposure to FEA tools (ANSYS, SolidWorks Simulation) for basic structural or thermal analysis. Hands-on experience with rapid prototyping — FDM/SLA/SLS printing, laser cutting, hand-fabrication. Awareness of environmental testing (vibration, shock, thermal cycling) and how design choices affect outcomes.

Substantive final-year project, hackathon, or club work (Formula Student, robotics, aero-design, satellite teams).
