About Dioxycle
Dioxycle is pioneering breakthrough carbon utilization technologies that convert industrial emissions into sustainable chemicals with unprecedented energy and cost efficiency. By displacing fossil fuels for the production of key chemicals, Dioxycle has the potential to ultimately reduce over 800 million tons of CO2 per year, representing over 2% of the world's emissions.
At the core of our process is a novel "carbon electrolyzer", a machine capable of using just electricity and water to convert carbon emissions back into valuable everyday essential chemicals. Our team is innovating across chemical, mechanical and system engineering to turn carbon transformation into an economically feasible, industrial reality through this completely novel technological approach. Having completed our industrial-scale electrolyzer prototype, we are now working with our chemical and downstream offtakers towards First-of-a-kind plant deployment and subsequent commercial roll-out.
We are supported by world-class funders including Bill-Gates-founded Breakthrough Energy Ventures, Lowercarbon Capital and Gigascale Capital and have raised $40M to date. We operate from two centers in Paris and California (so whether you are passionate about outdoors or good food/art scenes, we have a location for you to join!)
Your Mission
Dioxycle is seeking a Product Development Engineer to join our design team. You'll be working on end-to-end development of our electrolyzer stacks, at the intersection of mechanical design, breakthrough electrochemistry, and manufacturing - taking concepts from CAD to physical reality, and iterating fast.
This is a role for someone who thinks rigorously, builds pragmatically, and isn't afraid to get into the details of a component tolerance or a supplier negotiation. You'll have real ownership over a core piece of our technology. The problems are hard, the impact is direct, and the work is never boring.

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 Testing: Design and execute test campaigns to evaluate gas-adsorption capacity, pressure drop across beds, regeneration behavior, and thermal/energy efficiency. * Root-Cause Analysis: Diagnose technical issues, trace failure modes in air/gas handling loops, and convert experimental data into clear mechanical design improvements. * Subsystem Integration: Collaborate closely with mechanical, electrochemical, and controls teams to integrate air systems with cell modules, sensors, and structural housings. * Technical Documentation: Document system architecture requirements, piping and instrumentation diagrams (P&IDs), process concepts, and validation outcomes. YOUR PROFILE * Education: Bachelor’s or Master’s degree in Mechanical Engineering (strongly preferred) or a highly related discipline (such as Process/Chemical Engineering with a heavy, proven focus on physical machine design and plumbing). * Direct Air Capture (DAC) Background: Practical, hands-on experience in Direct Air Capture (DAC), gas-adsorption systems, or closely related gas-purification technologies. * Prototyping & Plumbing Mastery: Strong physical troubleshooting and assembly skills. You must be completely comfortable working with pumps, pneumatic valves, compression fittings, tubing, vessels, and gas sensors in a workshop or laboratory environment. * Analytical Skills: Strong ability to interpret process data, model flow behaviors, and perform thermodynamic or mass-transfer calculations. Experience with MATLAB, Python, or automated control systems is an advantage. * Pragmatic and Autonomous: Highly self-directed, resourceful, and excited to build experimental setups from scratch in a fast-paced hardware scale-up environment. * Communication: Flawless professional English. Able to explain complex air-processing dynamics clearly to cross-functional battery development teams.
