Head of Business Development

Endurance is building the world's first modular subsea geothermal power plants, converting vast thermal resources under the ocean into gigawatts of baseload power. Backed by Founders Fund, Felicis, First Round Capital, and Point72 Ventures, our founding team includes veterans from SpaceX, Helion, and Robinhood. We have completed multiple deep-ocean deployments and are launching a long-term demonstration project this fall. By leveraging modular design, manufacturing scale, efficient drilling, and latent cooling on the seafloor, we are pioneering a new category of energy that outperforms traditional sources on both environmental impact and cost.

As the Head of Business Development at Endurance, you will own commercial strategy, customer development, and deal execution across the Pacific Ocean, Endurance's target market, from the first power offtake agreements today to the bankable, multi-gigawatt project pipeline that defines the company's long term commercial trajectory.

You will be in the room with utility executives, hyperscaler infrastructure leaders, sovereign energy authorities, and defense program offices, structuring the deals that translate Endurance's technology into committed contracts, capital, and customers. In the near term, that means driving the commercial thread with hyperscaler partners on subsea pilots, structuring offtake and partnership terms for our first commercial projects, leading commercial work on the US federal lease and Program of Record path, and developing the partnership architecture for our Japan and broader Pacific opportunities.

You will be expected to operate with extreme ownership over Endurance's commercial outcomes. If a customer conversation stalls, a deal structure isn't penciling, a partnership is drifting, or a procurement window is closing, you are the person driving resolution.

At the same time, you will build the commercial organization required to scale Endurance into a world-class energy company. This includes hiring and leading the power sales, offtake, partnerships, and BD operations team, developing the bankability framework that every project opportunity is filtered against, establishing commercial standards and deal-review processes, and defining the eventual commercial architecture of a company selling firm clean power across the Pacific.

The ideal candidate is equally comfortable structuring a power purchase agreement, negotiating a strategic partnership with a hyperscaler, briefing a sovereign energy minister, sitting through a DoD technical exchange, hiring senior commercial talent, and defining the commercial operating system of a future gigawatt-scale energy company.

You will work with the CEO and COO on the highest-leverage commercial conversations, and you will partner closely with the Head of Policy and External Affairs, who runs the regulatory and government relationship layer where commercial and policy work intersect. You will be a peer to the Head of Policy and External Affairs and on the leadership team.
