About the Company The open ocean is Earth’s largest and most power-dense renewable energy resource. Panthalassa is harnessing that resource to generate the cheapest energy on the planet. Our mission is to provide abundant and affordable clean energy for everyone.

We are rapidly scaling high-power test infrastructure for compute, power electronics, and turbine systems while bringing online state-of-the-art manufacturing equipment across multiple sites. In this environment, identifying creative, practical solutions that enable the delivery of sufficient power—quickly and reliably—will be a key contributor to the company’s success. Founded in 2016 and based in the Pacific Northwest, our team comes from diverse backgrounds in aerospace, naval architecture, marine operations, hardware, software, and research.

About the Job We are building a core technology designed to operate in the harshest, most unpredictable environments on Earth, the world’s oceans. Delivering on this mission requires not only elite engineering talent but a work environment that runs smoothly, scales intelligently, and frees our team to focus on solving impossibly hard problems. We are looking for an Electrical Infrastructure Engineer to serve as the technical authority for the design and evolution of electrical infrastructure across our facilities.

This role spans existing operations and new build-outs, covering infrastructure upgrades, new facility diligence, design input, installation, commissioning, and long-term system performance. This is a design-forward role for someone who understands how power infrastructure actually gets delivered today, how to source it, design it, and scale it under real-world constraints. You will develop strategies to unlock megawatt-scale capacity quickly by combining traditional and non-traditional infrastructure approaches.

You are comfortable working upstream, shaping electrical architecture, identifying risks early, and translating evolving engineering needs into practical, buildable infrastructure plans that can be executed with quality and speed.
