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 Electromechanical Technician to join our systems team. You'll be working directly on the systems that operate our electrolyzer stacks in a hands-on role assembling, maintaining and troubleshooting automated test benches. You will apply mechanical, electrical, and software skills in your every day work, contributing to continued improvement and operation of our extensive electrolyzer test systems.   Your key responsibilities will center around: - Maintain and trouble-shoot PLC-based control systems (Beckhoff) on our lab and field electrolyzer units.  - Wire, install, and troubleshoot sensors, actuators, electrical panels, valves and pumps - Troubleshooting and maintenance of test benches, including instrumentation and controls - Testing and validation of the sub-systems through the implementation of test protocols - Implementation and tuning of PID controllers - Writing of documentation - Benchmark suppliers and contact them - Maintain inventory and improve the inventory system
