You will own the complete thermal architecture of the SAR Antenna Unit, ensuring stability, performance, and reliability from concept definition through on-orbit validation.\nResponsibilities:\nDevelop detailed orbital thermal models (steady-state & transient).\nPerform high-fidelity thermal simulations for gradients, distortions, and thermo-elastic effects.\nConduct coupled thermal-structural analysis for dimensional stability.\nDefine and implement thermal control strategies (MLI, coatings, heaters, isolators).\nEstablish temperature, distortion, and alignment budgets aligned with RF performance.\nSupport deployable antenna design with thermal expansion evaluations.\nDevelop and validate Thermal Mathematical Models (TMM) and correlate with TVAC test data.\nSupport environmental testing (thermal balance, TVAC, vibration-thermal interaction).\nCollaborate with RF, structural, AIT, and Bus teams for compatibility.\nGenerate and present reports for PDR, CDR, TRR, and QR reviews. •Drive root-cause analysis for thermal anomalies and corrective iterations. •Mentor junior engineers in thermal modelling and best practices.\nRequirements\nMust-have Qualifications:\n3-6 years of hands-on experience in spacecraft or aerospace thermal design & analysis. \nStrong expertise in orbital thermal analysis and spacecraft environments.\nProficiency in Simcenter 3D (thermal & coupled thermal-structural analysis).\nDeep understanding of thermo-elastic distortion and dimensional stability.\nStrong knowledge of passive & active thermal control techniques.\nExperience correlating thermal models with thermal balance and TVAC test data.\nSolid understanding of aerospace materials and thermal properties (CTE, conductivity, emissivity).\nAbility to translate RF performance constraints into thermal/mechanical design requirements ( efficient\nthermal dissipation from IC and RF PCBs, EMI/EMC of the enclosure, etc)\nStrong technical documentation and design review participation.\nGood-to-have:\n\nExperience with radar or high-frequency RF payloads.\nFamiliarity with deployable structures.\nWorking knowledge of structural FEA workflows in Simcenter 3D (NX Nastran).\nExperience designing thermal aspects of test support equipment.\nExposure to spacecraft Bus thermal interface design.\nExperience with heater control electronics and sensor placement strategies.\nBackground in thermal-optical property characterization.\nPrior flight hardware qualification experience.\nExperience in fast-paced private aerospace or new-space environments.\nWhat We Look For:\n\nOwnership mindset and ability to lead complex thermal design efforts.\nCuriosity and eagerness to solve multidisciplinary challenges.\nAdaptability to fast-paced start-up environments.\nStrong analytical and problem-solving skills.\nPassion for aerospace and enthusiasm to contribute to real-world satellite missions.\nBenefits\nCompetitive compensation aligned with market standards. \nExperience rapid growth in a start-up culture.\nFlexible working hours.\nOpportunity to work closely with the Founding Team.\nMentorship from advisors with decades of aerospace experience.","description_format":"text","description_chars":3208,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Flexible
