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 optomechanics, structural/thermal/dynamics analysis, build & alignment, environmental testing (vibe/TVAC), and documentation—working closely with optics, detector/ROIC,

electronics, and systems engineering.

Responsibilities

- 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.

Must-have Qualifications

- 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).
- Robust 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.

Good-to-have

- 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.

What we look for :
- 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
