Arbor Energy
El Segundo, CA, USA
Posted on Sep 4, 2025
At Arbor, 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’re drawn to rigorous work with lasting impact, we’d love to hear from you. Come build what the future will run on.
We are seeking a Sr. Turbomachinery Aerodynamics Engineer to define operating characteristics and design high-performance flowpaths, airfoils, and inlet/outlet geometries for a supercritical CO₂-based power cycle.
