We focus on reducing the cost and complexity of hydrogen production so it can replace fossil-based alternatives across real-world applications. We’re an early-stage team working at the intersection of electrochemistry, manufacturing, and deployment.About The Role\nWe are looking for an engineer with a few years of established experience to own the thermal, fluid, and pressure aspects of our alkaline electrolyser stack and balance-of-plant systems.We are developing enclosed multi-cell modular stack architectures with strong parallels to modern chlor-alkali cell design. As we scale from kW to MW-class systems, we need someone who understands electrolyte circulation, gas-liquid separation, thermal management at 80-100°C, and pressure balancing between hydrogen and oxygen sides.\nThis is a hands-on as much as analytical role. You will model and simulate, but you will also be on the shop floor commissioning what you designed, troubleshooting what didn’t work, and iterating in real time. We need someone equally comfortable with a process simulation and a pipe wrench. We are not looking for another team leader - we need someone who wants to get their hands dirty and go deep on the engineering.\nDirect experience with alkaline water electrolysers or chlor-alkali cell technology is strongly preferred. However, if you bring deep thermal engineering and process design experience from a related field and can demonstrate strong thermofluid fundamentals, we want to hear from you. As we move toward our first pilot deployments - including at international partner sites - you should be comfortable travelling and supporting commissioning beyond the Milton Park workshop.\nVisa sponsorship is available for the right candidate.\nTasks\nOwn thermofluid design of multi-cell alkaline electrolyser stacks: flow distribution, gas management, thermal behaviour\nDesign and optimise electrolyte circulation for uniform distribution across cells in enclosed modular configurations\nDevelop thermal management strategies for operation at 80-100°C\nModel and validate pressure balancing between O₂ and H₂ sides, including differential pressure control and its safety implications\nDesign BOP from P&ID through to component specification: pumps, heat exchangers, separators, valves, piping\nPerform mass and energy balances across operating conditions\nSpecify materials for hot KOH service\nCommission, test, and troubleshoot the systems you design - hands-on on the shop floor\nContribute to HAZOPs and pressure system compliance (PED, PSSR)\nAnalyse test data and feed insights back into design iterations\nSupport the coordination and commissioning of pilot deployments at partner sites, including internationally\nEssential Skills\nDegree in Mechanical, Chemical, Process, or Thermal Engineering\nApproximately 3 to 6 years of relevant experience\nStrong thermofluid engineering fundamentals: heat transfer, fluid mechanics, two-phase flow, thermal system design\nExperience with process design: P&ID development, mass and energy balances, component specification\nUnderstanding of gas-liquid separation and thermal management in process systems\nKnowledge of materials selection for aggressive chemical environments\nHands-on and rig-competent: comfortable commissioning, plumbing, and troubleshooting the hardware you design\nComfortable working with pressurised systems\nDesirable Skills\nDirect experience with alkaline water electrolysers or chlor-alkali cell technology (strongly preferred)\nExperience with multi-cell, bipolar, or enclosed cell stack configurations\nThermal engineering experience: heat exchanger design and selection, thermal transient analysis, cooling system design\nProcess engineering experience in chemical, petrochemical, or energy sectors\nExperience with enclosed or zero-gap cell designs\nProcess simulation or CFD experience (ANSYS, COMSOL, Aspen, or similar)\nPED, PSSR, or EN 13445 compliance\nHydrogen safety, DSEAR, ATEX\nPP, PVDF, or PFA piping for caustic service\nWillingness to travel internationally for pilot commissioning and partner site work\nSpanish language skills \nFull UK driving licence\nYour profile\nYou’ve spent a few years working on alkaline electrolysers, chlor-alkali cells, or in thermal and process engineering in a demanding industrial environment. You understand thermofluid realities - how flow distributes, where heat builds, what happens when a pressure balance shifts. You’re as comfortable with a process model as you are tracing a problem on the shop floor. You want to own the domain in a company where the stack architecture is still being shaped, not execute someone else’s spec. The prospect of helping commission our first pilot systems - including at international partner sites - excites rather than daunts you.Why us?\nOwn the entire thermofluid and BOP domain for a next-generation alkaline electrolyser\nShape stack architecture where design decisions still matter\nYour models get validated on real hardware in the same building\nSmall team, high ownership, direct collaboration with the CTO\nBe involved in our first international pilot deployments\nCompetitive salary and benefits","description_format":"text","description_chars":5222,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[{"language":"Spanish","level":"All levels","optional":true}]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-04T20:21:29Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"evidence":"Licensed UK visa sponsor (Skilled Worker)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Skilled Worker","cap_exempt":false,"checked_at":"2026-10-21T06:25:45+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":7,"band":"cold","label":"Long shot","p_open":1,"p_active":0.24,"p_room":0.28,"age_days":169,"expected_fill_days":22,"reasons":["conf:4","win:tail","crowd:"],"computed_at":"2026-10-21T05:46:15Z"},"pay":null,"html_url":"https://alion.io/job/electrogenos-stack-thermofluidic-engineer","json_url":"https://alion.io/job/electrogenos-stack-thermofluidic-engineer.json","meta":{"generated_at":"2026-10-22T06:05:10Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":811,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-23T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":3910537},"rest":"https://alion.io/mcp/rest/get_company?id=3910537"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Felectrogenos-stack-thermofluidic-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Felectrogenos-stack-thermofluidic-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Felectrogenos-stack-thermofluidic-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/electrogenos-stack-thermofluidic-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Felectrogenos-stack-thermofluidic-engineer"}]}
