Backed by leading European VCs and with commercial agreement from Lufthansa and MB Energy, we are deploying our first commercial facilities to prove commercial viability in the next 12 months.\nOur Process Validation Team scales up the electrolysers that release CO₂ from its captured state. As a working student, you work hands-on at electrolyser and stack level: you build, test and analyse larger-scale hardware that moves our technology toward industrial scale. No sandbox projects, just real hardware and real results.\nHow you'll contribute\nAssemble, disassemble and inspect electrolyser cells and stacks following defined build procedures\nPrepare and run tests on our larger-scale test stands, including pre-test checks such as leak testing\nSupport accelerated stress tests (ASTs) to evaluate electrolyser durability\nRun degradation studies on key stack components such as membranes, electrodes and seals\nPerform post-test teardowns and failure analysis at stack and component level, and document root causes\nAnalyse test data and turn it into clear, actionable findings for the team\nKeep the test area safe, organised and well documented\nYour first 6 months in the roleWeek 1-4: Get to know the team, our technology and our test stand setup. Learn our assembly procedures, safety standards and documentation practices. Support stack builds, test runs and teardowns under supervision.\nMonth 2-3: Assemble and disassemble stacks independently. Run standard test protocols including ASTs, analyse results and maintain detailed test logs. Contribute to failure analysis reports and improve our documentation.\nMonth 4-6: Own a technical workstream, such as AST protocol development, a component degradation study or stack failure analysis. Design hypothesis-driven tests and collaborate with modelling, systems, process engineering and our fundamental lab team. Optionally, scope a thesis project around your work.\nAbout you\nMust-haveEnrolled in a Bachelor’s or Master’s in Chemistry, Chemical, Mechanical or Process Engineering, or a related field\nFirst experience in electrochemistry or electrolyser/fuel cell technology\nComfortable with hands-on mechanical work and handling larger hardware\nStructured and detail-oriented, especially in documentation and systematic failure analysis\nAble to work independently and as part of a tight-knit team of scientists, engineers and technicians\nEager to learn fast and see your experiments make a measurable difference\nFluent English, written and spoken\nNice-to-haveEnrolled in a Master’s program\nHands-on experience with test rigs or hardware assembly, e.g. from lab work or projects like Formula Student\nWhat we offer\nMeaningful work with direct impact on global decarbonisation\nReal hardware and real responsibility from day one\nRoom to grow and shape your role, including the option to write your thesis with us\nFlat hierarchies, no micromanagement and close collaboration across teams\nFounders who invest time in building a healthy, sustainable organisation\nOpen and transparent communication on company development\n20 days vacation plus public holidays to rest and recharge\nNoteworthy points\nThis role is fully on-site at our Essen location. Remote work is not possible, so you should live within commuting distance.\nWorking hours: 20 hours per week during the semester\n Ready to help build the fossil-free future?
