Phd Electrochemistry Jobs (NOW HIRING)

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 electrolyzer, using 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.

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!)

Dioxycle is seeking a hands‑on Senior Electrochemist to join our Menlo Park‑based electrochemical R&D team. You will develop and test novel, high‑impact electrolyzers and demonstrate state‑of‑the‑art performance metrics across multiple product streams. Your role is instrumental in transforming identified market opportunities into world‑class electrolyzers that economically produce clean chemicals.

To thrive in this role, you should be a hands‑on scientist with a strong understanding of electrochemical kinetics and transport. Ideal candidates can design experimental campaigns that deliver clear answers to key research questions, and can equally approach problems from fundamentals or simple models to guide research direction. If you are comfortable questioning hypotheses and proposing alternative explanations grounded in fundamentals, you will be a great fit for the team.

• Design and execute experimental plans and/or models that provide unambiguous answers to key research questions about our electrolyzers
• Conduct hands‑on experimental work and data analysis to improve electrolyzer efficiency
• Apply electrochemical techniques to evaluate the performance and durability of electrolyzer components, from new electrodes to cell hardware
• Work cross‑functionally with Process Engineering, Design, and other chemistry teams to align on the critical path to product success
• Actively foster a culture of safety in the lab

• PhD in electrochemistry and/or equivalent industry experience
• Expertise in electrochemical testing including EIS, Tafel analysis, cyclic voltammetry techniques, and related techniques
• Experience developing electrochemical kinetics or transport models is preferred, but applicants without this experience are still encouraged to apply
• Fluency in reading and digesting literature, and translating findings into relevant tests
• Strong project management skills: planning, anticipating blockers and removing them before they materialize, and delivering objectives on time
• Comfortable dealing with international and diverse teams
• Hypothesis driven: you rapidly test hypotheses, don't get attached when one is proven wrong, and quickly move on to the next

• CAD experience designing electrolyzer hardware
• Experience troubleshooting instrumentation or electromechanical hardware
• Experience with electrodialysis, salt splitters, or other acid/base generating cells is a plus

• 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

• 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

• 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 followed by a brief case study and technical questions, with Josh (Lead Electrochemist)
• Cofounder interview with David (Co‑founder & CTO)
• Onsite interview with opportunity to see the lab & have lunch with the team!
• A series of reference calls with provided contacts
