Role Overview

We're looking for a Senior Environmental, Health & Safety Engineer to be Arbor's first dedicated EHS hire. You'll build our safety program across our El Segundo shop and lab, our hot-fire test site in San Bernardino, and the first-of-a-kind power plant we are now engineering. At the test site we run a direct-fired supercritical CO₂ combustion loop on natural gas and oxygen. Today, safety at Arbor is owned by the engineers who do the work. We want to keep it that way while giving them the structure, tools, and expertise to do it well as the team grows.

This is a hands-on engineering role. You'll walk systems down before hazardous operations, sit in readiness reviews, write hazardous-operations procedures alongside the test engineers, and help design the controls that let the team move quickly without trading away safety. You co-sign procedures and readiness reviews; the responsible engineer owns the go decision, and you make sure it's made with hazards understood and controls in place. When something can't be done as planned, we'll look to you to help develop a better plan.

You'll report to the Head of Systems Engineering and split your time between El Segundo and the test site, with more time on site during first-time operations and, later, at our first-of-a-kind plant during construction and commissioning.
