Sr. Heat Exchanger Engineer

<div class="content-intro"><h2><span style="color: rgb(0, 0, 0);">About Us</span></h2> <p><span style="color: rgb(0, 0, 0);">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. </span></p> <p><span style="color: rgb(0, 0, 0);">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.  </span></p> <p><span style="color: rgb(0, 0, 0);">If you share our values and are drawn to rigorous work with lasting impact, we’d love to learn more about you.
