Serious engineering, real responsibility, and problems worth solving.
At Arbor, we’re focused on one of the defining energy challenges of this century: delivering fast, emissions-free baseload power to meet the world’s growing needs.
Joining Arbor means working alongside engineers, operators, and builders who pair technical excellence with genuine care for the world around them.
We champion the success of our people, partners, and planet, nurturing excellence through camaraderie and rigor.
We build for tomorrow, ensuring every bolt we tighten and every hand we lend leaves our environment stronger than we found it.
We embrace the unknown with curiosity, using courage and discipline to transform uncertainty into opportunity.
I’ve worked with many caring and talented people in my career, and this team truly stands out.
In Japanese, there’s a word, ikigai—a sense of purpose. Arbor has given me that feeling.
Working at Arbor has truly been the most satisfying two years of my career.
With a culture that values not just the planet, but each person on it, the insane amount of experience and technical talent, and the ‘mission-critical’ problems we’re addressing, I’ve thoroughly enjoyed the opportunity to work with this team on such an important goal.
A big part of what drew me to Arbor was the opportunity to apply my relatively niche rocket propulsion engineering expertise toward developing a system that can simultaneously generate baseload power while durably sequestering carbon.

Piece by piece, ATLAS is coming together.
Last week at our test site in San Bernardino, the team installed the turbocompressor onto ATLAS, our 1-megawatt pilot system, and completed its integration with CHAD, the CO₂ Heat Addition Device that brings carbon dioxide to turbine-ready conditions.
With these major subsystems now connected, we’re getting ready for the next round of integrated testing.
Last week, the team spun the turbomachinery in ATLAS, our 1-megawatt pilot system, to ~35,000 RPM on cold CO₂.
ATLAS is the first full-stack system we’re building to validate Arbor’s approach to clean, dependable baseload power. In this run, the gaseous CO₂ bearings behaved as designed, the shaft was thrust-balanced in fluid CO₂, and the system held steady throughout. These initial tests set the foundation we need before moving toward hot-fire operation.
There are still details to refine, but this run cleared an important technical gate.
