Panthalassa is a renewable energy and ocean technology company that builds autonomous, ocean-powered nodes that generate electricity from wave energy and run AI computing onboard.
<h4><strong>About the Company</strong></h4> <p>We are a renewable energy and ocean technology company committed to rapidly developing and deploying technologies that will ensure a sustainable future for Earth by unlocking the vast energy potential of its oceans. Our focus is on capturing civilizational levels of ultra-low-cost renewable energy for applications including computing and affordable renewable fuels delivered to shore. Our core technology is the node, a device that produces energy in the ocean’s harshest conditions for years at a time without human maintenance or intervention.</p> <p>The company is a public benefit corporation headquartered in Portland, Oregon, and backed by leading venture capitalists, philanthropic investors, university endowments, and private investment offices. We operate as an idea meritocracy in which the best ideas change the company’s direction on a regular basis.</p> <h4><strong>About the Job</strong></h4> <p>We are building hardware that has to survive real ocean conditions.
