About the company:

At Dioxycle we develop electrolyser solutions for carbon dioxide emissions. Using state-of-the-art technology, we research and provide technology that captures and converts carbon dioxide and ultimately generates valuable chemical products. 

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 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 $37M 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 dynamic Junior R&D Chemical Engineer to join our team at this pivotal phase of transition from R&D to industrial piloting. You will be leading testing and building of larger-scale next-generation electrolysis stacks to optimize them for peak performance and operation. This is a pivotal role at the heart of the engineering team, translating innovations from smaller to larger scale to validate design choices. It's the perfect role for you if you like to get off your computer and enjoy hands-on building, testing and problem-solving!

Key Responsibilities:
- Contribute to retro-planning experimental plans and conducting them
- Mount, assemble, maintain and disassemble novel experimental electrolyzer stacks
- Maintain the balance of plant (pumps, piping, thermal management, etc.) of the electrolyzer stack in collaboration with our System engineers.
- Develop & manage quality control, sensor calibration and testing campaigns
- Troubleshoot processes & optimize novel electrolyzer stacks (large-scale)
- Carry out observation & analysis to develop deeper understanding of stack behaviour (Failure Mode and Effects Analysis (FMEA), Root cause analysis, etc)
- Work with the MEA engineering team to ensure efficiency and durability are maintained in the electrolyzer scale-up(s)
- Work with the Stack design team to communicate experimental findings and ensure optimization of future designs

We seek a Junior R&D Chemical Engineer who is dedicated to advancing our mission and possesses the skills outlined below. We are looking for a recent Master's degree graduate, but are also open to candidates recently graduated from a PhD. Candidates with a minimum of one year of relevant experience are encouraged to apply.

  • 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 12 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

  • 2 x 30 minute intro call with the team to understand your career expectations, and answer your questions 
  • 60-minute technical video call with a presentation about yourself and brief case study, followed by technical questions, with Fanny (Head of MEA Engineering) and David (Co-founder & CTO)
  • Onsite interview to meet the team, see the lab & have lunch with the team!
