Senior Environmental, Health & Safety; EHS) Engineer

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 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.

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.

• Build and own Arbor's EHS program: site-specific Injury and Illness Prevention Programs, hazard communication, lockout/tagout (including pressurized and fluid energy), hot work, confined space, electrical safety, contractor control, incident investigation, and the training behind them.
• Formalize test-operations safety with the test team: hazardous-operations procedures, exclusion zones and personnel control, pre-test readiness reviews, and post-test debriefs. Be on site for first-time hazardous operations.
• Lead hazard analyses (JHA, What-If, PHA/HAZOP-style) for new hardware and new operations, and manage change so the analysis stays true as things evolve.
• Bring engineering judgment to oxygen, natural gas, high-pressure CO₂, and cryogenic systems—oxygen compatibility, siting and separation, relief and venting, asphyxiation monitoring—and review designs early so controls are engineered in rather than procedural.
• Lead incident and…
