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.

About The Job

We are seeking a Lead Fluids Engineer to join our team and provide technical leadership for the mechanical design and development of our core technology, the "Node." The Node is a device designed to produce energy in the harshest ocean conditions for extended periods without maintenance. This role is crucial to the success of our mission. Fluids are at the core of how our node operates. You will be responsible for the designs and eventually the team that designs all fluid systems in our nodes.

This is a role that requires extensive design and analysis experience, abilities to make outstanding technical contributions, and leadership abilities that are effective in a humble and high performance culture. While defining the design for our Node fluid systems, you will build and manage a team to support the future iterations of our Nodes. The ideal candidate is a technical expert and a practical builder comfortable with personally conducting detailed design work, values working alongside our manufacturing team, and is a skilled leader who has well developed interpersonal skills and a passion for developing others. You must thrive in a creative, scrappy, and collaborative environment.

Our staff have worked at organizations such as SpaceX, Blue Origin, Stoke, Boeing, Virgin Orbit, Virgin Galactic, Google, Amazon, Microsoft, New Relic, Bridgewater, 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. If you are an excellent engineer and technical leader, regardless of your background, we want you to apply.
