Mechanical engineer

PpbbMission /b /b /p /ppWe are offering a position as mechanical engineer in the Group of Energy Materials at EPFL, Sion. Our highly interdisciplinary Lab (20 FTE, 1/3rd PhD students, 1/3rd postdocs, 1/3rd engineers) is part of the EPFL Mechanical Engineering Institute and specialised since 30 years in fuel cell and electrolysers, especially for high temperature (600°C, solid oxide ceramics) and more recently also for low temperature (100 °C, protonic and anionic exchange membrane polymers). Our fully equipped diagnostics lab mounts and investigates fuel cells / electrolysers, from components and single cells up to stacks and small systems (10 – 50 kW), testing durability/performance and identifying degradation phenomena. Experimental work is assisted by modeling and simulation on different levels. /p pWe look to complement our engineer team. We design and build stacks, and different customized test benches to characterize our fuel cells, electrolysers, and more complex integrated systems including heat exchangers, chemical reactors, gas recirculation, safety sensors etc. /p pWe are specifically looking for an additional mechanical engineer with a solid experience in computational fluid dynamics and structural mechanics. These competences will be applied during the design of low and high temperature fuel cells and electrolysers, including their balance of plants, under pressurized conditions. /pppbbMain duties and responsibilities /b /b /p /p pMore specifically, within our ongoing projects, you will:  /p lihelp to finalize our main demonstration installation (10/30 kW full seasonal storage) /li lihelp to construct our 30 kW chemical reactor (20 bar) /li lideal with compression of H2, CO2, syngas (20-30 bar), and natural gas grid injection (5 bar)  /li limanage a 100-kW Power-to-Methane project including a novel electrolyser unit /li limaintain and modify existing test benches  /li lisupport the design of new test benches (up to 30-50 kW / 50 bar) /li liparticipate in the design of pressurised fuel cell / electrolyser concepts /li ppbbProfile /b /b /p /p liMSc degree in Mechanical Engineering /li liPrior professional experience with process flow diagrams, PID and HAZOP. /li liPrior professional experience with pressurization. /li liPrior familiarity with fuel cells, electrolysers, chemical reactors is a plus but not a must. /li liGood communication skills and working as part of a team /li liEnthusiasm, curiosity, motivation, reactivity, organizational skills, rigor in experimental work /li liAt least good command of English and preferably also of French (though not mandatory for French) /li ppbbWe offer /b /b /p /p liEmployment at a renowned institution ranked among the leaders in engineering and technology /li liSupport for professional development through training and continuous learning opportunities /li liSupportive and flexible work environment promoting work-life balance /li liLanguage courses relevant to your role /li liInternational multilingual working environment /li liDiscounts on public transport /li ppbbInformations /b /b /p /p pYour application should contain: /p p• A motivation letterbr/• Your detailed CVbr/• Contact information /p p• Names and contact information of 2 or more references willing to write a recommendation letter /p pApplication deadline: Apr 15th 2026br/Contract Start Date: June 1st 2026 or as per mutual agreement /p pActivity Rate Min: 80%br/Activity Rate Max: 100%br/Contract Type: yearly renewedbr/Duration: up to 5 years /p pOnly applications submitted through the online platform are considered. /p pFor more information, please contact: , , , , /p
