You will be joining the SAR Antenna Unit (SAU) team as a Senior Thermal Design & Analysis Engineer. You will own the complete thermal architecture of the SAR Antenna Unit, ensuring stability, performance, and reliability from concept definition through on-orbit validation.
Responsibilities:
â Own the thermal architecture of the SAR Antenna Unit end-to-end.
â Develop detailed orbital thermal models (steady-state & transient).
â Perform high-fidelity thermal simulations for gradients, distortions, and thermo-elastic effects.
â Conduct coupled thermal-structural analysis for dimensional stability.
â Define and implement thermal control strategies (MLI, coatings, heaters, isolators).
â Establish temperature, distortion, and alignment budgets aligned with RF performance.
â Support deployable antenna design with thermal expansion evaluations.
â Develop and validate Thermal Mathematical Models (TMM) and correlate with TVAC test data.
â Support environmental testing (thermal balance, TVAC, vibration-thermal interaction).
â Collaborate with RF, structural, AIT,
and Bus teams for compatibility.
â Generate and present reports for PDR, CDR, TRR, and QR reviews.
â Drive root-cause analysis for thermal anomalies and corrective iterations.
â Mentor junior engineers in thermal modeling and best practices.
Requirements
Must-have Qualifications:
â 3–6 years of hands-on experience in spacecraft or aerospace thermal design & analysis.
â Strong expertise in orbital thermal analysis and spacecraft environments.
â Proficiency in Simcenter 3D (thermal & coupled thermal-structural analysis).
â Deep understanding of thermo-elastic distortion and dimensional stability.
â Robust knowledge of passive & active thermal control techniques.
â Experience correlating thermal models with thermal balance and TVAC test data.
â Solid understanding of aerospace materials and thermal properties (CTE, conductivity, emissivity).
