Product Development Engineer

Ore Energy B.V. Product Development Engineer - Air Systems Amsterdam Full-time Permanent employee Apply for this job The role At Ore Energy, we are on a mission to fundamentally expand the amount of energy society can reliably harness and use, helping move civilization toward a more abundant energy future. We are doing this by developing long-duration, utility-scale iron-air batteries that provide safe, low-cost, multi-day energy storage for electricity grids and data centers. We are expanding our product development capabilities and are looking for a Product Development Engineer - Air Systems to join our team in Amsterdam. Our iron-air batteries "breathe" air, meaning that conditioning and purifying incoming air and managing gases internally is a critical subsystem of our product. In this role, you will lead the design, process calculation, prototyping, and validation of our air-processing and gas-management support systems. We are looking for a highly resourceful, hands-on Mechanical Engineer who has practical experience in Direct Air Capture (DAC) or advanced gas-adsorption technologies. You will bridge the gap between process concepts (mass balance, pressure drop, sorbents) and physical mechanical reality, building functional physical systems that protect and optimize our battery chemistry. This role reports directly to the Chief Product Officer (CPO) . Key responsibilities - System Design & Sizing: Design and develop active air-treatment, gas-separation, and humidity/temperature conditioning subsystems. Perform key process calculations, mass balances, flow dynamics, and system sizing. - Component Selection: Evaluate, specify, and source active mechanical components, including sorbents, filters, gas membranes, reactors, valves, pumps, and blower systems. - Hands-on Prototyping: Build, plumb, and wire laboratory-scale proof-of-concept units and pilot-scale air-handling rigs from scratch. - Experimental Testin...
