Dioxycle

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 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!)   Your Mission Dioxycle is seeking a hands-on Automation & Electrical Engineer to join our hardware team. You'll be working directly on the control systems that operate our electrolyzer stacks - programming PLCs, maintaining wiring and instrumentation, and helping us build a scalable deployment architecture as we grow from 40 systems to many more.   This is a role for someone who loves being close to the hardware, is comfortable picking up new tools quickly, and wants to see the direct impact of their work on real physical systems. You'll have real ownership over a critical part of our systems, at a moment when the team and the fleet are both growing fast. The problems are hard, the impact is direct, and the work is never boring.    Your key responsibilities will center around: - Program and maintain PLC-based control systems (Beckhoff) on our lab and field electrolyzer units. This covers lab-scale test units of small and medium size but also includes onsite industrial-scale pilots (that are so big you need to lift them with a crane) - Wire, install, and troubleshoot sensors, actuators, and electrical panels - Work with our team to configure new systems and contribute to how we standardize deployments going forward - Collaborate with Dioxycle's software engineers to integrate HMI graphics with control logic - Participate in the retrofitting of legacy systems with new-generation PLCs - Occasionally interface with existing C-based code on older systems   We're open to a few different profiles - what matters is curiosity, hands-on instinct, and a real interest in automation work. Experience with PLCs is a huge plus.
