About the Role

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!)
