Executive Assistant to the CEO

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.

This is an opportunity to become a trusted working partner to a fast-moving founder and CEO, building and operating the core systems that keep his professional and personal worlds running smoothly as priorities change. This is a hands-on role that offers an unusually close view into building an ambitious hard-tech company and considerable latitude to improve how the CEO operates.

Working closely with the Chief of Staff to the CEO, you will have broad ownership over the CEO’s day-to-day and meaningful freedom to make it work better. You will execute across inbox management, calendaring, travel, coordination, events, external engagements, and personal logistics. The work requires sound judgment at every level and a no-task-too-small mindset.

You may be a career EA, or you may have built the same muscles in another demanding environment. You hold an exacting standard for your work, notice details others miss, and follow through reliably. You combine low ego and high energy with warmth, good humor, and polish. You communicate exceptionally well, handle sensitive information with absolute discretion, and are energized by the pace and variety of the role.

The CEO’s work does not always fit within fixed processes, and the day will not always unfold as planned. Success requires someone who can build useful systems without becoming overly attached to them, and who can persist, redirect, and adapt without creating friction. In return, the role offers remarkable scope, ownership, and proximity to consequential work, along with the opportunity to become indispensable to a founder building something exceptional.
