Lead Combustion Engineer
El Segundo, CA
About UsAt 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.
Our Lead Combustion Engineer serves as the technical authority pioneering our rocket-inspired, high-pressure oxy-fuel combustion systems - integral in delivering carbon-neutral and carbon-negative power cycles at scale.
In this leadership role, you'll own the combustion subsystem, guiding a talented team through end-to-end development of breakthrough, high-efficiency devices in a fast-paced, collaborative startup environment. You'll drive strategy from clean-sheet concepts and advanced modeling through hands-on testing, rapid iteration, and performance validation, establishing the technical direction that powers a sustainable future.
You'll mentor junior engineers, align cross-functional efforts with test, analysis, and design teams, and make critical trade-off decisions to accelerate progress while pushing the boundaries of efficiency and reliability.
This is an onsite opportunity in our El Segundo, CA office.
