Grant & Proposal Writer

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.

In this role, you will translate complex energy systems, engineering processes, and regulatory requirements into clear, accurate documentation for a variety of audiences— from technical specialists to community members. This is an excellent opportunity for a detail-oriented communicator eager to build a career at the intersection of energy, science and technical writing. Experience in the environmental, geology, energy generation, maritime, or utilities sectors is highly prioritized.
