Thermal Design Engineer - SAR
On-siteBengaluru, Karnataka, India
Job Summary
Develop the thermal architecture for the SAR payload to ensure compliance with mission and instrument thermal requirements. Perform thermal analysis for all mission phases, including launch, ascent, orbital operation, eclipse, and safe modes. Design passive thermal control systems such as multilayer insulation, thermal coatings, radiators, and conductive interfaces. Evaluate active thermal control needs including heaters and temperature control electronics. Develop detailed thermal mathematical models and perform steady-state and transient simulations to evaluate payload performance under expected orbital environments. Collaborate with structural, mechanical, RF, electronics, systems, and mission engineers to deliver a reliable, flight-qualified payload. Support thermal design optimization, environmental testing, and in-orbit commissioning from a thermal engineering perspective.
Required Qualifications
- Bachelor's or master's degree in mechanical engineering, Aerospace Engineering, or a related field
- 4+ years of experience in thermal engineering for aerospace, spacecraft, or high-reliability systems
- Strong understanding of heat transfer principles, including conduction, convection, and radiation
- Experience developing thermal mathematical models for complex engineering systems
- Knowledge of spacecraft thermal environments and orbital heat loads
- Experience with thermal control materials and hardware used in spacecraft
- Familiarity with thermal design verification and environmental testing
- Strong analytical, problem-solving, and technical documentation skills
Desired Qualifications
- Experience in spacecraft payload thermal design
- Knowledge of Synthetic Aperture Radar (SAR) payload architecture and operational requirements
- Experience with spacecraft thermal analysis software such as Thermal Desktop, FlowTherm, ICEPACK, or equivalent
- Familiarity with finite element analysis (FEA) tools for coupled thermal-structural analysis
- Experience with thermal vacuum (TVAC) and thermal balance testing
- Experience in thermo-elastic analysis and dimensional stability assessment
