Prototype Technician

About CURA

CURA is a Canadian climate technology company working to change how one of the world’s most essential materials is made. Cement is responsible for approximately 8% of global CO₂ emissions. Our mission is to eliminate those emissions by becoming the default technology for cement production everywhere.

Our electrochemical process splits limestone into lime and a pure stream of CO₂ for storage or use, with the potential to reduce emissions by up to 85% while lowering energy use and manufacturing costs. Designed to be retrofit-ready, it integrates with existing feed stocks, infrastructure and operations. CURA is working toward bringing a 30,000-tonne-per-year commercial demonstration facility online in 2028.

Led by experienced climate technology founders, we collaborate with cement producers, engineers, researchers and industry partners around the world to move breakthrough technology from the lab to industrial scale. We are building a team of curious scientists, inventive engineers and practical problem-solvers who enjoy tackling big challenges together. We combine scientific rigour with an entrepreneurial culture that values collaboration, creativity, learning and fun.

Safety is fundamental to how we work. CURA maintains a strong safety culture, and every team member completes occupational health and safety orientation and role-specific training.

As CURA's Prototype Technician, you are the hands that turn designs into working hardware. You will build, assemble, and instrument the single-cell and multi-cell electrolyzers and test rigs our scientists and mechanical designer put on paper, then run them through the validation and testing that shows whether a design holds up. You'll also prototype and refine components at the bench — fabricating parts, building jigs and fixtures, and adjusting fits — so the team can iterate quickly.

This role exists because our path from lab to commercial scale runs through physical iteration. Someone has to make parts real, get them running, and generate the data that proves or disproves each design decision. If you like working with your hands on real hardware and care about getting both a clean build and a clean test result, this is where that happens.

• Use CAD (Solid Works) to model and detail parts, jigs, fixtures, and prototype components, and produce clean drawings for fabrication.
• Assemble, operate, and maintain single-cell and multi-cell electrolyzer test systems, including preparation of components, electrodes, membranes, electrolytes, and test fixtures.
• Fabricate and prototype parts, jigs, and fixtures through machining, 3D printing, and hand fabrication; refine fits and tolerances at the bench and coordinate parts with outside machine shops and vendors.

• Set up, instrument, and commission electrolyzer test rigs and benches, including fluid handling (pumps, flow controllers, valves), gas handling for the CO₂ stream, sensors, and data acquisition systems.
• Support commissioning and testing of prototype electrolyzer stacks, including startup/shutdown procedures, monitoring, and performance evaluation.

• Execute validation and test procedures — leak and pressure testing, sealing integrity, durability, and behaviour under operating conditions, as well as polarization curves, efficiency measurements, and stability testing.
• Collect, organize, and analyze experimental data to evaluate performance, identify issues and failure modes, and support the next design iteration.

• Develop and maintain test procedures, build records, and documentation so that builds and results are consistent and repeatable.
• Troubleshoot mechanical, fluidic, and assembly…
