Lead Mechanical Engineer, Motor/Generator

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. 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 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. As the Lead Mechanical Engineer, Motor/Generator, you will lead the technical vision, execution, and continuous improvement of the rotating machinery that turns mechanical power into electrical power and vice versa. You will be responsible for the end-to-end development, from conceptual design through manufacturing, assembly, and test. You will work closely with our in-house electromagnetics, electrical engineering, fluid dynamics, manufacturing, and testing teams to drive the development, fabrication, and testing of the generator and/or motor, ultimately ending in its deployment in the Node at sea. This is a roll-up-your-sleeves leadership role in which you'll prototype, build, and troubleshoot alongside world-class engineers and technicians. Candidates should have strong interpersonal skills and thrive in a creative, scrappy, and collaborative environment in which the best ideas change the company's direction on a regular basis. If you are an excellent engineer, regardless of your background, we want you to apply. Our staff have worked at organizations such as SpaceX, Blue Origin, Boeing, Tesla, Apple, Virgin Orbit, Astra, Google, Amazon, Microsoft, New Relic, Bridgewater, Raytheon, Disney Imagineering, and the US Army and Air Force, as well as research universities, startups, and small companies across a range of industries. We are organized as a public benefit corporation and are backed by leading venture capital firms, private investors, philanthropic investors, and endowments. We strive to be the best engineering team on the planet, and we compensate our engineers accordingly.
