Job Description

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 Chief of Staff to partner closely with our CEO and executive leadership team. This is a high-impact, strategic role designed for someone who thrives in a dynamic, fast-paced environment and has a proven ability to drive clarity, alignment, and execution across an organization.

This role manages the company’s operating cadence, drives communication from the executive team to the broader organization, and ensures leadership focus is consistently directed toward the initiatives that matter most.

• Ensure cross-team visibility through concise status updates, risk registers, and dashboards that inform action.
• Act as a connector across teams, ensuring alignment between leadership and functional leads, and proactively removing roadblocks.
