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.

This role provides direct support to a fast-moving CEO, designing and administering the core systems that keep his world running smoothly in a rapidly changing environment. This is a hands-on, high-trust role. Your job is to ensure nothing gets dropped and that the CEO is responsive, on time and prepared, and free to focus on the highest-leverage work.

This is a no-task-too-small role that requires sound judgment at every level. You work closely with the Chief of Staff to the CEO and own the CEO’s day-to-day, including inbox, calendar, travel, coordination, events, and external engagements, while also managing personal logistics to make his life run more efficiently. 

The work requires speed, discretion, strong writing, practical problem-solving, and context switching between professional and personal support throughout the day. You should be equally enthusiastic about coordinating a board meeting and picking up dry cleaning. 

You should be fastidious about excellence, extremely organized, attentive to detail, and motivated by the service function itself. You have low ego, strong follow-through, high personal energy, and the ability to be warm and good-humored while maintaining polish. You communicate clearly and effectively in writing and in person and handle sensitive information with absolute discretion. You are energized by the dynamic nature of the role. 

This is not a role for someone who needs a rigid operating system, a predictable workday, or a principal whose working style always follows a set process. This role requires a great degree of flexibility, and in return offers unusually valuable experience for someone wanting to sharpen their judgment in a high-dimensional environment while making a large impact.
