Spacecraft Thermal Engineer - ESATAN-TMS Expert

Redwire Space - External careerpage; Warszawa; Hybrid; PLN 120,000 - 180,000; Full time

Job summary

Redwire Poland is seeking a Thermal Engineer to join our international engineering organisation supporting advanced space systems programmes. The role focuses on spacecraft thermal modelling, analysis, and verification, with collaboration across systems, structural, and mechanical engineering teams to ensure optimal thermal performance throughout the project lifecycle.

Based in Warsaw under a hybrid work model, you will develop Thermal Mathematical Models, run analyses with ESATAN-TMS and ANSYS

Qualifications

• Degree in Aerospace Engineering, Mechanical Engineering, Physics, or another relevant engineering discipline.
• 3+ years of experience in thermal analysis of spacecraft, aerospace systems, or other high-reliability products.
• Hands-on experience with ESATAN-TMS, or strong experience with comparable thermal-analysis tools (such as ANSYS Thermal) and willingness to develop ESATAN-TMS capability.
• Experience developing and maintaining Thermal Mathematical Models.
• Thorough understanding of conductive, radiative, and convective heat transfer, together with the spacecraft thermal environment, including solar flux, planetary albedo and infrared radiation, eclipse conditions, spacecraft attitude, and orbital parameters.
• Good understanding of active and passive spacecraft thermal-control principles.
• Familiarity with thermal-vacuum and thermal-balance testing, including test preparation, predictions, instrumentation, execution support, and result assessment.
• Strong communication skills in English, including technical writing and presentation of engineering results.
• Strong analytical thinking and willingness to learn and develop within the space sector.

Responsibilities

• Develop and maintain Thermal Mathematical Models (TMMs) and Geometrical Mathematical Models (GMMs) for spacecraft, subsystems and equipment.
• Perform spacecraft-, subsystem- and equipment-, and component-level thermal analyses using ESATAN-TMS, ANSYS Thermal, and associated tools.
• Develop and assess representative thermal modelling approaches for advanced spacecraft structures, including sandwich panels and lattice-core structures.
• Perform thermal analyses for hot and cold bounding cases, nominal and contingency mission modes, and relevant operational scenarios.
• Support thermal design trade-offs, thermal budgets, requirements and interface assessments for spacecraft systems, equipment and structures.
• Prepare thermal predictions for TVAC and Thermal Balance test campaigns.
• Support thermal test execution and correlate analytical models with test results.
• Generate temperature maps and provide thermal inputs for thermo-elastic and structural analyses.
• Prepare thermal analysis reports, model documentation, verification evidence, and technical inputs to project reviews.
• Work closely with structural, mechanical and systems engineers, as well as AIT teams, throughout the project lifecycle.
