Senior Electrical Engineer

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. 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 Senior Electrical Engineer, you will work on an interdisciplinary team and be responsible for designing custom electronic hardware, taking system level concepts and requirements and turning those into fully-functional circuit cards that fulfill the system needs. Candidates should have strong interpersonal skills and be able to 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, Stoke, Boeing, Virgin Orbit, Virgin Galactic, Google, Amazon, Microsoft, New Relic, Raytheon, Disney Imagineering, Bridgewater Associates, 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. Responsibilities Be responsible for the design of high-reliability electronics throughout their lifecycle by working with a team of engineers. Specific tasks may include design of: multi-kilowatt load engagement systems; high energy storage battery selection; battery management systems including high precision state-of-charge monitoring and active current limiting; supercapacitor bank design; power electronics system architecture including switch-mode power electronics circuit cards. Candidates should be intimately familiar with requirements capture & refinement, block diagramming, schematic and PCB design, electronics hardware packaging, component selection, circuit analysis, circuit simulation, procurement, prototyping, documentation, manufacturing, unit testing, and deployment. Test and verify the designed hardware in a lab environment, building/integrating multiple systems where the designs are utilized, and transferring test requirements to test engineering for large-scale manufacturing. Create unit and integration test processes to ensure design validity and reliability, and exercise prototypes past their thermal, mechanical, and electrical limits to understand failure modes. Collaborate effectively across interdisciplinary engineering teams. Prepare supporting safety and engineering documentation for your designs and be responsible for the training and safety of any technicians who operate or test it.
