Twelve

Transforming CO2 into valuable products, making essential chemicals and fuels from air.

Company Profile

Twelve (formerly Opus 12) is a pioneering climate tech company dedicated to transforming carbon dioxide into essential products. Founded in 2015 as a spin-out from Stanford University, their mission is to create a fossil-free future by making CO2 a valuable resource. Twelve's proprietary technology uses electrolysis to convert CO2 emissions, water, and renewable electricity into a wide range of critical chemicals, materials, and fuels that are currently derived from fossil sources. This process, which they call 'carbon transformation,' offers a pathway to decarbonize hard-to-abate industries like aviation, plastics, and automotive.

The engineering culture at Twelve is highly interdisciplinary, bringing together electrochemists, chemical engineers, materials scientists, mechanical engineers, and software developers. It's an environment of rapid experimentation, scientific rigor, and practical application. Engineers are encouraged to innovate, optimize processes, and scale up complex electrochemical systems from laboratory to industrial scale. There's a strong emphasis on safety, efficiency, and developing robust, commercially viable solutions. The team is driven by a shared commitment to addressing climate change through innovative chemical engineering and sustainable manufacturing.

Twelve has achieved significant milestones, including successful demonstrations of their technology to produce various chemicals and fuels, partnering with major industrial players, and securing substantial funding. Their unique value proposition lies in their ability to create high-value products from a waste stream (CO2), offering a circular economy solution that reduces both emissions and reliance on fossil fuels. For job seekers, Twelve offers the opportunity to work at the cutting edge of sustainable chemistry and industrial decarbonization. It's a chance to apply scientific and engineering expertise to a tangible solution for climate change, contributing to a new paradigm of manufacturing.

Their tech stack involves complex electrochemical reactor design, process control systems, materials science for catalysts and membranes, and data analytics for process optimization. Software development focuses on automation, sensor integration, and data management (Python, MATLAB, LabVIEW, various SCADA systems). Working at Twelve means joining a passionate and brilliant team dedicated to building a sustainable industrial future. It's an ideal place for individuals who are excited by the challenge of scaling novel chemical processes, want to make a direct impact on reducing carbon emissions, and thrive in a fast-paced, innovative R&D and manufacturing environment.
