Product Development Engineer (Paris)
About the Company
This is a climate-tech company developing electrochemical technology that converts industrial CO2 emissions into sustainable chemicals, aiming to displace fossil fuels in chemical production. Their team works across chemical, mechanical, and systems engineering. Having completed their industrial-scale prototype, the company is now moving toward first-of-a-kind plant deployment and commercial roll-out.
The company is backed by climate-focused investors and has raised venture funding to date.
The Mission
The company is seeking a Product Development Engineer to join its design team, working on end-to-end development of 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. The role carries real ownership over a core piece of the company's technology.
Key responsibilities:
- 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, chemistry, and scale-up teams
- Lead manufacturing planning, procurement, and supplier relationships for the stack product
Abilities and expertise sought
- 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, and solid mechanics (compression, material resistance) is a nice to have
- Good knowledge of suppliers for prototype component manufacturing
- Experience in electrolyzer or fuel cell stack design (e.g. hydrogen electrolysis or chlor-alkali electrolysis) is a nice to have but not a requirement
- English is the daily working language
Mindset sought
- Strong work ethic and self-driven attitude
- Resourceful problem-solver who finds a way with the means available
- Committed to a kind, high-performance, and fun on-site work culture
- Passion for innovation
- Willing to go the extra mile on deliverables
- Humble, low-ego, and curious
