About The Position

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’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. Mechanical Engineer (Gasification) to take ownership of the development, testing, and optimization of our novel biomass gasification systems, solids feed and removal systems, and feedstock pretreatment systems to enable reliable, high efficiency conversion as we scale from demonstration to pilot and beyond. As a core member of a small, hands-on gasification team, you’ll guide daily operations, exe
