Optomechanical Engineer

GalaxEye; Bengaluru; On-site; INR 1,200,000 - 1,800,000; Full time

Job summary

GalaxEye in Bengaluru seeks an experienced Opto-Mechanical Engineer to own the design, analysis, integration and qualification of an MSI payload for space applications. You will work across precision optomechanics, structural/thermal/dynamics analysis, build and alignment, environmental testing, and documentation with cross-functional teams.

The role requires hands-on development, AIT planning, and ensuring launch load survivability and alignment retention through testing and verification.

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.
• Strong CAD/FEA skills with space/defense payload exposure is a plus.
• Experience with optical alignment and tolerancing methods.
• Ability to perform structural and thermal analysis (ANSYS/NASTRAN).
• Experience supporting integration & environmental tests (vibe/TVAC) preferred.

Responsibilities

• Design and analyze opto-mechanical assemblies for MSI payload subsystems.
• Manage optical-mechanical interfaces: alignment features, tolerance stack-ups, thermal focus stability, stray light baffle interfaces.
• Perform 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 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.
• Design test fixtures and support tooling (including whiffletree-style supports for large optics), MGSE concepts, and alignment jigs.
• Produce and maintain drawings, GD&T, BOMs, assembly instructions, tolerance reports, test reports, and change logs.

Job description

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:
• 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).
• 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
• 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. 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,
• Familiarity with space materials and processes: anodize, passivation,
• Understanding of ECSS/NASA design review expectations and FMEA/FTA exposure.
