Banyu Carbon aims to radically reduce the cost of carbon capture, hasten the transition to a net zero carbon economy, and slow the effects of global warming. To meet this challenge, Banyu Carbon is developing a process to extract CO2 from seawater using light-activated chemicals that is projected to require a fraction of the energy inputs compared to competing carbon capture methods. We are transitioning from prototypes in the lab towards a larger scale pilot and first-of-kind commercial facility. We have secured a carbon removal pre-purchase contract with Frontier, closed an oversubscribed financing round, and are supported by a stellar team of investors.

Banyu Carbon is a fast-paced research and technology development startup located on the campus of a major research university in beautiful Seattle. Gain experience bringing science to market. Put your passion for the planet and for science to work at Banyu Carbon!

Summary: We seek a highly motivated and creative chemist or chemical engineer to help develop and optimize our carbon capture process. The individual must be passionate about applying fundamental chemical and engineering principles to develop scalable industrial processes.  The focus of this position will be developing and evaluating methods for transferring ions between solutions in the absence of applied electric fields. Candidates may have a background in separation processes, analytical chemistry, and/or process engineering. The ideal candidate will have extensive experience in the theory, testing, prototyping, and scaling of ion exchange processes, for example using ion exchange resins. The successful candidate will work collaboratively with a small team of scientists and engineers to advance our carbon capture technology from concept to deployment.

Salary: A starting salary of $110,000-150,000 per year is expected.

Position Type: This is an in-person regular full-time position located in Seattle, WA.

Desired Start Date: As soon as possible.
