Twelve is pioneering a new industrial era with carbon transformation. We use electrochemistry to turn CO2 into critical products—fuels, chemicals, and materials—that today rely on fossil fuels. Our mission: to fundamentally change how the world makes its essential goods by transforming CO2 from a liability into a resource, building resilient, fossil-free supply chains, and advancing next-generation industry.
As a critical part of Twelve’s development of a first-of-a-kind process for producing sustainable aviation fuel from CO2, the stack testing program sits at the interface between lab-scale and commercial production units. In this role, you will be a key member in the operation, maintenance, and troubleshooting of Twelve’s CO2 electrolysis systems. You will engage in activities including electrolyzer stack install, start up, operation, and replacement, as well as equipment maintenance and troubleshooting. Additionally, you will monitor and collect data to help maintain and improve performance, and provide feedback to our development teams.
The Stack Operator will be responsible for ensuring that all operations tasks are performed safely and according to the relevant operating procedures. The position will be mainly located in Tulsa, Oklahoma to operate our next generation electrolyzers.
This role is fixed-term with a 4-month employment period.
