At KaleidEO, we are committed to shaping the future of Earth Observation and putting Indian space tech on a global map, and we invite you to be part of this exciting journey.
Roles and Responsibilities
- Thermal design of hi-res electro-optical payloads to minimize image distortion and maintain alignment under orbital variations.
- Contribute to the selection of materials and coatings for thermal stability and survivability in space.
- Participate in the setup and execution of thermal vacuum (TVAC) tests and interpret the results.
- Assess and control the impact of thermal variations on image quality and component alignment.
- Collaborate with the optics, electronics, mechanical, and systems teams to develop practical, integrated solutions.
- Perform STOP (Structural-Thermal-Optical Performance) analysis to assess image plane movement and wavefront error sensitivity.
- Thermal design and analysis of electronic subsystems within payloads.
- Model heat flow, temperature distribution, and thermal gradients using tools likeSiemens NX or ESATAN.
- Assist in designing thermal paths for critical components such as optical elements, focal plane arrays, and high-power PCBs.
- Prepare technical documentation, test reports, and thermal budgets under the guidance of senior engineers.
Qualifications
- B.E./B.Tech or M.E./M.Tech in Aerospace, Mechanical, or Thermal Engineering.
- 2–5 years of hands-on experience in thermal analysis for space systems, with contributions to hardware that flew or reached thermal qualification.
Must have
- Strong understanding of thermal fundamentals (conduction, radiation, contact resistance) in vacuum environments.
- Experience with thermal modeling tools (NX, ESATAN, Thermal Desktop, or equivalent).
- Familiarity with electronics thermal management — power maps, thermal vias, heat-spreading, and packaging constraints.
- Understanding of thermal control strategies for space systems (active/passive cooling, low-jitter control).
- Basic knowledge of coating materials, emissivity/absorptivity trade-offs, and implementation of passive control components (MLI, isolators).
Good to have
- Experience designing for both optical stability and electronics survivability in LEO satellite missions.
- Experience contributing to or executing TVAC test campaigns, thermal correlation, and post-test analysis.
- Basic understanding of multiple domains of satellite engineering, such as in-orbit operations, and the effect of thermomechanical distortions on image quality.
- Experience with thermal-structural coupling in systems involving optics and large thermal swings.
