Are you passionate about decarbonization and looking to help solve climate change? Are you looking for a challenge in a fast-growing DeepTech start-up? Join our team as a Mechanical Engineer in the stacks team.

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.

Our team is innovating across chemical, mechanical and system engineering to turn carbon transformation into an economically feasible, industrial reality by developing a completely novel technological approach. Having completed our medium-scale Proof-of-Concept electrolyzer, we are now working towards a first-of-its-kind large-scale industrial prototype and are assembling key partnerships for future commercial roll-out.

We are supported by world-class funders including Lowercarbon Capital, Breakthrough Energy Ventures and Gigascale Capital and have raised $26M to date. We operate from two R&D centers in Europe and California.

Joining us now is an opportunity to play a fundamental role in the scale up of our transformative technology by working closely with our international founding team. If you are motivated by solving hard problems, meaningfully addressing climate change, and want to join the fastest growing industry of our generation, then this role may be for you!

Dioxycle is seeking a dynamic, hands-on and experimentalist-minded Mechanical Engineer who, in collaboration with our stack team, will be in charge of the development of our electrolyzer products. We are seeking a technically adept individual who is enthusiastic about applying their engineering expertise to foster innovation in electrolysis.

- Mount, assemble and maintain novel electrolyzer stacks. The job is hands-on: it is particularly well-suited to those who like to get off their computer!

- Maintain the balance of plant (pumps, piping, thermal management, etc.) of the electrolyzer stack in collaboration with our System engineers.

- Aid in the mechanical design of the electrolysis stack to improve performance

- Perform experimental analysis: documentation, post-processing and interpretation of electrolyzer performance

- Develop & manage quality control, sensor calibration and testing campaigns

- Work with the R&D team to deepen understanding of, and unlock improvements in, electrolyzer performance

Location: Onsite in Paris, France

- Master's degree in Engineering (Mechanical, or a related field e.g. IUT diploma in Physics).

- Minimum 2 years work experience (3-4 is preferred)

The position offers a clear path for professional growth within Dioxycle, with the possibility to advance into a specialized role focused on technological development (for example, a manufacturing or research-oriented role).
