About the RoleWe build high-performance optical payloads for satellites. We are looking for a junior opto-mechanical engineer with a solid grounding in structural simulation to join our payload team. You will analyse how launch loads and on-orbit thermal environments affect optical performance, and work with the design, optics, and AIT teams to make sure our payloads meet their requirements from design through qualification.Key Responsibilities

- Build and run FE models of optical assemblies (mirrors, lens mounts, metering structures, baffles, and mounting interfaces) using ANSYS, Nastran/Patran, or Abaqus

- Run static, modal, random vibration, sine, and shock analyses against launch environment specifications

- Perform thermo-elastic and steady-state/transient thermal-structural analyses to predict distortion and defocus over the operating temperature range

- Support STOP (Structural-Thermal-Optical Performance) analysis

- Size and assess flexures, bonded joints, fasteners, and kinematic mounts, and estimate stresses, margins of safety, and stiffness

- Support trade studies on materials and structures (Invar, aluminium, titanium, CFRP, SiC, Zerodur, fused silica)

- Correlate models with test data (modal survey, vibration, thermal-vacuum) and update models accordingly

- Work with mechanical design, manufacturing, and vendors to keep designs producible and analysis-consistent

- Maintain clear documentation, model version control, and traceability to requirements





Required Qualifications

- B.E./B.Tech or M.E./M.Tech in Mechanical, Aerospace, or a related discipline

- 1-3 years of hands-on experience in structural FEA (industry, research, or a substantial project or internship)

- Working knowledge of at least one major FEA tool (ANSYS Mechanical, or equivalent)

- Solid fundamentals in strength of materials, vibration, and heat transfer

- Understanding of GD&T; and precision manufacturing constraints

- Comfort with 3D CAD (SolidWorks, or similar) and preparing geometry for meshing and simplification

- Ability to interpret results critically, including mesh convergence, boundary conditions, and sanity checks against hand calculations

- Clear technical writing and communication skills

Preferred Qualifications

- Exposure to optical or precision structures such as mirror mounts, lens barrels, telescopes, or camera assemblies

- Basic understanding of optical systems and how structural deformation affects image quality

- Familiarity with composites (CFRP laminates), bonded joints, or low-CTE materials

- Experience with space, aerospace, defense, UAV environmental standards and test campaigns

What You'll Gain

- Direct involvement in flight optical payload programs.

- Close mentorship from senior engineers and program leads

- Broad exposure across structures, thermal, optics, and manufacturing

- Room to grow into a lead analysis or opto-mechanical design role
