Laboratory Technician

CT19 is working exclusively with an early-stage climate technology company based in Paris developing a novel electrochemical process aimed at dramatically improving energy efficiency and cost in carbon management technologies. The team is growing quickly and is backed by experienced advisors and strong technical collaborators. This is an opportunity to join at a formative stage and contribute directly to the development of a breakthrough climate solution.

About the Role The team is recruiting a hands-on Lab Technician to support the assembly, operation, and testing of experimental hardware central to the company’s core technology. Working closely with engineers and scientists, you will help build and maintain electrochemical and mechanical systems, operate test benches, and monitor experiments in a fast-paced R&D environment.

This role requires precision, reliability, and a strong safety mindset. You will work with sensitive instrumentation, pressurised systems, chemicals, and both wet and dry lab procedures. Your work will directly enable rapid experimentation and iteration, and your observations will inform improvements in both product design and lab processes.
