Senior Process Engineer

Are you excited by the potential of large-scale carbon removal? If so, Captura Corp. is seeking a Senior Process Engineer. Captura is an early-stage technology start-up with the mission to develop globally scalable carbon removal to support a sustainable future for the world's climate. Captura's unique technology was developed and proven in Caltech's laboratories and uses established electrochemical concepts to enable gigaton-scalable solutions for removing carbon dioxide (CO2) from the atmosphere via direct ocean capture. We capture carbon dioxide using only renewable electricity and seawater, creating no byproducts. CO2-depleted seawater is returned to the ocean to absorb CO2 that comes from the atmosphere. Job Overview We are seeking a highly skilled and experienced Senior Process Engineer to join our growing startup at a pivotal early stage in our polymer production operations. This is a unique opportunity to help shape and build our production capabilities from the ground up. The ideal candidate will have strong hands-on technical expertise, a proven track record of driving process improvements in a production environment, and the ability to work effectively with cross-functional, diverse teams. They will take full ownership of critical projects in a fast-paced setting, playing a key role in ensuring smooth, efficient production operations while driving continuous improvements in both process performance and safety. Key Responsibilities Process Engineering & Technical Operations Select and specify appropriate pumps for chemical systems including monomers, polymers, and slurries. Design and size key equipment such as condensers, heaters, and chillers. Develop and maintain detailed Standard Operating Procedures (SOPs) for processes such as polymerization, precipitation, and drying. Perform chemical usage and cost calculations per batch for accurate budgeting and forecasting. Conduct complete mass balance calculations for all production processes. Oversee chemical ordering and inventory management to maintain supply continuity while minimizing overstock. Develop and manage a list of critical spare parts and oversee their procurement and inventory. Maintenance & Equipment Plan and execute proactive maintenance programs to maximize production up time.
