About the Company
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.
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.
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.
About the Job
We are developing a core technology, the “Node”, that will operate in the worst conditions the world’s oceans have to offer for years at a time without human maintenance or intervention.
As a Mechanical Engineer, you will support the design of numerous mechanical components and assemblies that must withstand extreme loads and a harsh ocean environment. You will support subsystem design through trade studies, CAD modeling, analysis, lab testing, and deployment preparation. This position requires a highly motivated, hands-on engineer who thrives in ambiguity, can execute with autonomy, and is eager to take on end-to-end ownership, defining requirements and architecture and driving through design, prototype testing, and final build. We expect you to be especially strong in analysis and to gravitate toward first-principles, fundamental-physics approaches to problem solving.
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. You will own your designs cradle-to-grave, from first concept through fabrication and deployment at sea. If you are an excellent engineer, regardless of your background, we want you to apply.
