Sr. Process Engineer (El Segundo)

Sr. Process Engineer

We are seeking a Senior Process Engineer to develop and own process engineering deliverables for modular process units such as biomass gasification, oxy-combustion, supercritical CO2 power generation, CO2 purification and liquefaction, and wastewater treatment. As a process engineer at a fast-paced company developing novel technology, you'll participate in a wide range of activities from conceptual studies through plant commissioning, startup, and troubleshooting. As projects move into the detailed engineering and construction phases, you will be responsible for managing EPC process engineering efforts to ensure successful project execution.

This Senior role also involves the establishment of internal documentation, standards, and work processes. The ideal candidate has experience across the project lifecycle from conceptual design through detailed design, commissioning, and operation. Hands-on experience with construction or field troubleshooting is also highly valued.

Arbor's team of world-class engineers and scientists is developing a scalable, low-cost approach to Bioenergy with Carbon Capture and Storage (BECCS) based on modern rocket engine technology. BECCS is a carbon dioxide removal (CDR) approach that uses biomass to produce energy and remove CO? from the atmosphere and store it permanently underground, while ensuring food security, rural livelihoods, and biodiversity are not affected. Our modular technology leverages the power density of supercritical CO2 to enable compact gasification, oxy-combustion, and high-pressure turbo-expansion to convert abundant waste biomass into clean electricity, water, and high-purity CO2, capturing and sequestering all emissions from the process. Our team brings together a passion for science, technology, and global stewardship to make low-cost, high-quality carbon removal and baseload power a reality.
