Design Engineer - Turbomachinery

About Us At Arbor Energy & Resources Corporation ("Arbor Energy"), we’re creating technology to power our lives while protecting the planet that sustains them. Our advanced power systems deliver clean, reliable baseload electricity with zero operating emissions—modular, fuel-flexible, and engineered for the realities of today’s energy demand. At the core is a supercritical CO₂ turbine with integrated carbon capture, designed to bring carbon-neutral power online quickly at meaningful scale. Our team includes aerospace engineers, combustion experts, and systems thinkers with a shared goal: to build technology worthy of the world we want to live in. While many of us began our journeys looking to the stars, we’re applying that expertise here at home to deliver dependable, emission-free baseload power and a future of lasting abundance. If you share our values and are drawn to rigorous work with lasting impact, we’d love to learn more about you. Come build what the future will run on. Steward our planet : We build for tomorrow, ensuring every bolt we tighten and every hand we lend leaves our environment stronger than we found it. Lead with Love : We champion the success of our people, partners, and planet, nurturing excellence through camaraderie and rigor. Explore the Uncharted : We embrace the unknown with curiosity, using courage and discipline to transform uncertainty into opportunity. Role Overview We are seeking a Mechanical Designer who will be responsible for the detailed modeling of components from a multidisciplinary team of engineers, integration of components into assemblies, and interfacing with manufacturing. You will also perform checking duties related to assembly and component drawings, part structures (BOMs) and item specific information for accuracy of design intent and application specific information. Arbor’s team of world-class engineers and scientists are   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 CO₂ 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. This is an onsite opportunity in our El Segundo, CA office.
