Electrical System Engineer

pOur IOD mission is on the clock and the electrical power system needs a dedicated owner. Some architectural decisions have been made, but everything from supplier selection to harness design to qualification is ahead of you. You'll be the only electrical engineer on the team, working within a broader engineering group that supports you, but the EPS is yours to drive from the decisions already taken through to flight-ready hardware. /p h3You will own /h3 pSize and specify the Electrical Power System: solar arrays, battery pack, and Power Converter Units, building on existing architectural choices and taking them to flight /p pDefine the power architecture in full: generation, storage, conversion, distribution, including redundancy philosophy, protection, and power modes /p pProduce and maintain the power budget, power margins, and operating scenarios /p pManage electrical interfaces between all subsystems: connectors, pinouts, ICDs, grounding, and return paths /p pDefine and design the spacecraft harness, including routing constraints, shielding, segregation, drawings, and manufacturing documentation /p pManage EPS component suppliers end to end: specification, procurement, technical follow-up, acceptance, and non-conformance handling /p pContribute hands-on to AIT and test campaigns: troubleshooting, functional tests, environmental testing support /p h3What we are looking for /h3 p2+ years of proven experience in spacecraft EPS, avionics power, or high-reliability embedded power systems (space preferred) /p pDegree in Electrical Engineering, or equivalent experience that tells the same story /p pExperience sizing and selecting solar arrays, batteries, PCUs/DC-DC converters, and power distribution and protection elements /p pAbility to create and maintain power budgets, margins, and mission power mode concepts /p pExperience with harness design and documentation: connectors, pinouts, routing constraints, manufacturing drawings /p pFamiliarity with EMC/EMI and grounding principles for mixed RF, power, and digital subsystems /p pHands-on experience with integration and testing, including lab equipment (PSU, electronic load, oscilloscope, DMM) and troubleshooting /p pUnderstanding of space constraints: thermal, radiation context, reliability, derating, workmanship /p pFluent English (our working language) /p pNice to have: experience with ECSS standards or similar space product assurance processes, battery safety and qualification exposure (cell selection, protection, charge management, abuse cases), experience defining EGSE and writing test procedures, TVAC and vibration test support from an electrical perspective, French language skills. /p h3You will fit if /h3 pYou want to be the single point of ownership for a spacecraft electrical system, not a contributor to one piece of it. /p pYou're as comfortable negotiating specs with a supplier as you are routing a harness or debugging a power anomaly in the lab. /p pYou make decisions with incomplete information when the timeline demands it, and you know how to protect margins while doing so. /p pYou care about robustness and simplicity over clever design, because what you build has to work where nobody can fix it. /p pThis is fully on-site in Villeneuve (VD). You'll be the only electrical engineer, which means the scope is wide and the decisions are yours. Some architectural choices are already made, others are open, and supplier selection is entirely ahead of you. The timeline is tight and real. What makes that worth it: every watt generated, stored, and distributed on our IOD spacecraft will run through a system you selected, specified, and qualified, and you'll watch it power a mission on the most ambitious space programme in Switzerland. /p #J-18808-Ljbffr
