Team & Culture:
You’ll join a tight, multidisciplinary payload group that owns the MSI instrument end-to-end: mission-driven requirements, optical/opto-mechanical design, camera + control electronics, firmware/FPGA, and hands-on integration & testing. We operate like a true startup engineering squad direct communication, rapid problem-solving, and shared ownership. Decisions are made with a systems mindset, and plans turn into hardware quickly. Expect deep collaboration with data, business, and spacecraft teams as we mature the payload from prototype to flight-ready hardware.
Role :
You will own opto-mechanical design, analysis, integration, and qualification of a Multispectral Imager (MSI) payload for space applications. This is a hands-on role spanning precision opto-mechanics, structural/thermal/dynamics analysis, build & alignment, environmental testing (vibe/TVAC), and documentation—working closely with optics, detector/ROIC, electronics, and systems engineering.
Design and analyze opto-mechanical assemblies for MSI payload subsystems (lens/telescope, focal plane module, baffles, mounts, mechanisms if any).
Manage optical-mechanical interfaces: alignment features, shimming strategy, tolerance stack-ups, thermal focus stability, stray light baffle interfaces.
Perform or lead simulations for static strength, thermal gradients, thermo-elastic deformation, and focus/boresight stability.
Assess thermal paths for vacuum conduction cooling; support heater/thermistor placement and thermal straps.
Execute modal, sine, and random vibration analysis; define and verify stiffness targets and resonance margins.
Own design for launch load survivability and optical alignment retention.
Hands-on build of prototypes and engineering models; develop alignment and integration procedures.
Plan and execute optical-mechanical verification tests; support metrology, collimator/goniometer/interferometer-based checks as needed.
Lead mechanical aspects of vibration, shock (if applicable), and thermovac campaigns: test readiness, fixtures, instrumentation, correlation vs models, NCR/RCA closure.
Design test fixtures and support tooling (including whiffletree-style supports for large optics where relevant), MGSE concepts, and alignment jigs.
Produce and maintain drawings, GD&T, BOMs, assembly instructions, tolerance reports, test reports, and change logs.
B.E./B.Tech/M.E. in Mechanical Engineering (or equivalent).
2–4+ years hands-on opto-mechanical experience in precision mechanisms or EO/IR payloads (space/defense/industrial imaging acceptable).
Strong SolidWorks or NASTRAN (or equivalent CAD): complex assemblies, sheet metal, drawings, configurations.
Working knowledge of optical alignment and tolerancing methods(CTE effects, stability, mounts, kinematic design concepts).
Ability to do structural + thermal analysis (ANSYS / NASTRAN / similar) and interpret results for design decisions.
Experience supporting integration & environmental tests (vibe and/or TVAC strongly preferred).
Be the SME for the Opto Mechanical design, create AIT and execute AIT test plans for building payloads and TVAC, Vibration testing with space garage testing.
Good engineering discipline: documentation, review readiness, systematic debugging and Systems thinking.
Experience with hyperspectral / multispectral cameras, star sensors, telescope/periscope structures.
Thermal design for vacuum: conductive cooling, thermal straps, heater control concepts, contamination-aware design.
Familiarity with space materials and processes: anodize, passivation, bonding/adhesives, torque specs, locking features.
Experience designing MGSE / alignment tooling; metrology experience.
Understanding of ECSS/NASA design review expectations and FMEA/FTA exposure.
Comfortable owning problems end-to-end: design → analysis → build → test → fix → document.
Bias for action and practical engineering judgment (trade-offs: mass, stiffness, thermal stability, manufacturability).
Clear communicator who can work tightly with optics/electronics/systems.
