Your missionWe're looking for a hands-on Structural & Thermal Engineer to take full ownership of structural analysis and thermal subsystem design for our instruments. You'll turn CAD into analysis models, tell us whether the design survives launch and orbit, and shape the hardware when it doesn't. From the first FEM mesh to the last thermal-vacuum cycle, this is your domain.What you'll doStructuralDefine requirements and load levels for payload unitsBuild structural FEM models of satellite systems and subsystems directly from CADRun static, modal, random vibration, sine and shock analyses at the relevant qualification and acceptance levelsFeed results back to the mechanical engineers and drive design changes where margins aren't thereOwn, plan and run environmental test campaigns (vibration, shock, thermal cycling, thermal vacuum): test plans, fixtures, facility coordination, execution and test-to-model correlationThermalBuild and run satellite thermal models based on CAD, thermal interfaces and power consumption profilesEvaluate power and heat balance across hot and cold cases and mission phasesFeed results back to mechanical and electrical engineers and drive design changes where margins aren't thereDefine the thermal control strategy, including MLI design, manufacturing and integrationDecide where temperature sensors and heaters go, and size the heater circuitsDocument analyses and test results to support design reviews and launch provider requirementsYour profileBachelor's or Master's in aerospace or mechanical engineering, or a related field4+ years of experience in structural and/or thermal analysis for space hardwareHands-on FEM experience (e.g. NX, Ansys, Femap/Nastran, Abaqus) including modal, random vibration and shock analysisThermal modelling experience with tools such as ESATAN-TMS, Thermal Desktop or SystemaExperience planning and running environmental qualification or acceptance testsWorking knowledge of ECSS standards and launcher environment requirementsComfortable working from CAD (e.g. SolidWorks, Siemens NX) and owning decisions end-to-endFluent EnglishNice to haveFlight heritage: you've seen your hardware through launchExperience with small satellites or airborne payloadsTest-to-model correlation of both structural and thermal modelsScripting (Python) to automate analysis and post-processingOptical or detector thermal stability requirements (e.g. LiDAR, hyperspectral instruments)Why us?Real ownership: the structural and thermal design of our satellites is yoursHardware that flies, on a mission that matters for the climateA small, hands-on team where your analysis directly changes the designBenefits such as Gym and Deutschlandticket subsidy.
