Key skills for this role
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 Naval Architect, you will be a critical contributor to the design and delivery of the Node’s hull - performing stability, weights, and seakeeping analyses; developing structural and mechanical designs; and driving drawing releases that keep fabrication on track.
Your work will ensure our ocean-deployed systems are seaworthy, fabrication-ready, and high-performing in the harshest marine conditions.
You will apply the lens of naval architecture across the Node program, driving requirements for stability, seakeeping, and marine operations.
You will also contribute to hydrodynamic analyses and lead multidisciplinary investigations into hydrodynamic loads.
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.
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.
