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 synthetic organic chemist, physical organic chemist, or scientist with similar skills, to develop and optimize organic photoactive molecules for use in our carbon dioxide removal process. The individual must be passionate about applying chemical principles to uncover structure-function relationships in photoactive compounds to optimize organic molecule performance. The candidate should have experience with and be comfortable with lab-scale organic synthesis as well as the characterization of new compounds. The ideal candidate will also have experience applying the principles of physical organic chemistry to guide molecule development and synthetic approaches. 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 $110,000-140,000 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.

Location: Banyu Carbon is located within CoMotion Labs on the beautiful campus of the University of Washington. This setting unites the fast paced and exciting environment of a startup with the thriving intellectual community and advanced instrumentation of a major research university.
