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 highly organized Senior Lab Technician to scale our lab operations and capabilities as we develop our novel catalysis technology. We are seeking a positive, hard-working and meticulous individual who is excited about using their energy to make our analysis pipeline runs smoothly and timely so that the Dioxycle team can drive further innovation in electrolysis and have a tangible impact on global emissions.

Key Responsibilities:

• Prepare samples for characterization on a daily basis
• Perform routine chemical and physical characterization, such as NMR, titration, DLS, compression tests, on a daily basis
• Prepare pilot-scale chemical feedstocks
• Carry out certain electrochemical characterization and contribute to development of new methods
• Take care of waste and gas management
• Ensure cleanliness and tidiness of our work spaces and help with daily cleaning
• Ensure sufficient consumable and lab supplies at all times
• Ensure safety rules are followed and assist in writing new rules, standard operating procedures and risk assessments
• Manage all collaborations with external laboratories for characterization techniques and write reports to share with the team
• Production of electrodes & carry out general lab operations (e.g. inventories, maintenance, quality control and testing) and automate tasks wherever possible
