About Dioxycle
Dioxycle is developing next-generation electrified chemical manufacturing technologies that produce cheaper, cleaner and sovereign critical chemicals, key to mining, energy infrastructure, pharmaceuticals, agriculture and consumer goods. Our technology uses electricity and widely available feedstocks (CO, CO2 emissions, salt streams) rather than fossil fuels, de-linking the production of critical chemicals from fossil-linked supply chains exposed to chokepoints, export bans, and price volatility.
We focus on chemicals where our direct electrified pathway simplifies complex multi-step fossil-fuel-based processes into fewer simpler steps; delivering a process that is both cleaner and cheaper. Having validated the superiority of our technology at our industrial module scale, we are now preparing for commercial deployment.
We are supported by world-class funders including Lowercarbon Capital, Breakthrough Energy Ventures 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.
Your key responsibilities will center around:
- Design new electrolyzer stacks using CAD software, from early concept to detailed drawings
- Dimension and validate components (manifolds, bipolar plates, sealing systems, compression systems) using theoretical calculations and computational simulations
- Own innovative product design initiatives in close collaboration with the stack team, chemistry team and scale-up team
- Lead manufacturing planning, procurement, and supplier relationships for your stack product
Abilities and expertise we are looking for
- 4+ years of hands-on experience in mechanical design
- Strong knowledge of mechanical parts and computer-aided design (CAD) is a requirement
- Solid experience in Product Lifecycle Management for design documentation and revisioning
- Manufacturing experience is strongly appreciated
- Solid theoretical knowledge in fluid mechanics, thermal management, solid mechanics (compression, material resistance) is a nice to have
- Good knowledge of suppliers for prototype components manufacturing
- Experience in electrolyzer or fuel cell stack design such as from hydrogen electrolysis or chlor-alkali electrolysis is a nice to have but not a requirement
- English is our daily work language.
Mindset we are looking for
- Exemplary work ethic and self-driven attitude: you get things done fast and to a high standard and you don't drop the ball
- "Street-smart": you don't take no for an answer and will figure out a way to solve anything with the means available
- Commitment to the mission and ambition and to creating a kind, high-performance and fun atmosphere at work (100% on-site role)
- Passion for innovation and problem-solving attitude
- Dedication to investing time and effort for the betterment of the team
- Going the extra 20% that makes a good deliverable into an outstanding deliverable
- Humble, low-ego and curious
What we have to offer
- Unique journey: We are an early-stage company with a world-class team and a flat structure.
- Impact: We are building a product that will reshape century-old industrial processes to build a better, more sustainable and resilient world
- People-first: We love our people. We are excited to see one another every morning when coming to work. We choose people and they choose us to share a similar excitement.
- Feedback over ego: We are self-improving whilst helping others grow. We are no-ego doers and we are all responsible for shaping the company.
- International team: We are an international team made up of over 17 nationalities, and hopefully many more soon!
- Fun: We constantly strive to cultivate a great work atmosphere and organize regular team events.
- Competitive compensation packages
- Generous Employee Stock Ownership plans
- Health Insurance: Medical, dental, and vision coverage.
- Ergonomic work stations & state-of-the-art equipment
Our process
- An initial video call with Grace, Director of People, to discuss Dioxycle's mission, get to know you, understand your career expectations, and answer your questions (30 mins)
- Expert screening call with Jan, Lead Stack Design Engineer (30 mins)
- Technical deepdive interview/case study with Jan, Lead Stack Design Engineer and Luc, Chief Stack Architect (1 hour)

The Company
What We Do
Dioxycle is a French-American technology startup that develops breakthrough electrochemical electrolysis technology to recycle industrial carbon emissions into sustainable chemicals, most notably ethylene. By replacing legacy fossil fuel-based crackers with a proprietary carbon electrolyzer powered by renewable electricity, the company aims to decarbonize heavy industry. This process has the potential to abate up to 800 million tonnes of CO2 annually, representing 1-2% of global emissions.
