Team & Role:

You will be joining the Satellite Bus team and working on building the spacecraft bus thermal system. You will own the thermal design and analysis of the satellite bus, ensuring all subsystems operate within allowable temperature limits across mission phases. The role involves developing and maintaining high-fidelity thermal models, defining passive and active thermal control strategies, and supporting integration and environmental testing to deliver a flight-ready spacecraft.

Responsibilities :
- Own spacecraft bus-level thermal design and analysis from concept through flight qualification.
- Define the thermal control architecture for the spacecraft bus (passive and active).
- Develop and maintain Thermal Mathematical Models (TMMs) using Siemens NX Space Systems Thermal (TMG) within Simcenter 3D.
- Perform steady-state and transient orbital thermal analyses.
- Perform first-principles thermal calculations for radiator sizing, heater sizing, and thermal margins.
- Design and implement passive thermal control measures including coatings, MLI, heat paths,



and interface conductance.
- Design active thermal control systems including heater sizing, zoning, redundancy, and control philosophy.
- Define thermal requirements, temperature limits, and verification matrices for spacecraft bus subsystems.
- Work closely with structures, avionics, EPS, propulsion, payload, and AIT teams to ensure thermal compatibility.
- Ensure corroboration of design with thermal vacuum (TVAC) and thermal balance testing.
- Perform thermal analysis for avionics and electronics components where required.
- Investigate and resolve thermal anomalies during integration and environmental testing.

Requirements
Must-have Qualifications :
- Bachelor’s or Master’s degree in Mechanical, Aerospace, or Thermal Engineering.
- 3–6 years of experience in spacecraft or aerospace thermal design and analysis.
- Mandatory hands-on experience with Siemens NX Space Systems Thermal (TMG) within Simce
