About Endurance

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, Blue Origin, and Apple. We have completed multiple deep-ocean deployments to subsea volcanoes 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 environmental impact, deployment speed, and cost.

What you'll be doing

As Power Delivery Engineer, you will be Endurance’s principal technical expert on power systems and grid interconnection. You will own the engineering required to get power from our subsea plants to the grid: interconnection strategy, system studies, protection, equipment specification, installation, and commissioning.

This role is for someone who has done this work hands-on and can do it again. On active projects you will bring in and manage an EPC, but you will be the person at Endurance who knows what good looks like, can check the work, and can do it yourself when needed.

Your work will span the full life of a project:

New opportunities. Quick feasibility analysis to determine whether a site or market can work, assessing grid capacity, interconnection pathways, cable routes, and landfall options. You will support business development, regulatory, procurement, and siting efforts, including leasing and permitting.

Projects entering development. Pre-FEED and early FEED power delivery engineering, including transmission architecture trade studies, early system studies, and equipment specifications. This work will support site acquisition and early infrastructure, feed requirements to the generator team, and kick off procurement of long-lead equipment like export cables and transformers.

Projects in execution. Select and engage an EPC for detailed engineering, procurement, and construction, then manage them through commissioning and energization.

Future technology. Advance the grid-tie technologies our future projects will depend on, such as higher-performance wet-mate connectors, subsea electrical equipment, HVDC, and submarine cable improvements. You will work with universities, research labs, vendors, and our internal teams to raise TRL ahead of the projects that need it.

You will be the primary engineer dedicated to power delivery at Endurance, working closely with electrical, mechanical, drilling, offshore operations, supply chain, regulatory, and business teams, and directly with the founding team and engineering leadership. As we scale from demonstration systems to commercial plants in multiple countries, the technical foundation you build will carry into every project we deliver.

Key Responsibilities

Serve as Endurance’s technical lead on power systems, transmission, and grid interconnection

Perform early feasibility analysis for new project opportunities in support of business development, regulatory, procurement, and siting efforts

Lead pre-FEED and early FEED power delivery engineering, including transmission architecture, voltage selection, export system design, and AC/DC trade studies

Take projects through the utility or transmission operator interconnection process, including applications, model submittals, study phases, and interconnection agreements

Scope and review utility interconnection studies, push back where needed, and run independent studies to anticipate results

Perform or direct plant-side power system studies, including load flow, short circuit, grounding, protection coordination, arc flash, harmonics, and cable ampacity

Develop protection philosophy and design protection and control systems for the plant and interconnection, including relay selection, settings, and coordination with the utility

Design or specify control house / E-house infrastructure, including layout, auxiliary power, HVAC, fire protection, and SCADA and communications
