About the role
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, 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. What you'll be doing As an Electronics Specialist at Endurance Energy, you will work alongside electrical and firmware engineers to design, build, debug, and maintain the electrical systems that power our test infrastructure and offshore deployments. You will be responsible for building high-quality harnesses, assembling and wiring PLC and power cabinets, performing PCBA rework and debugging, and ensuring our lab operates at a professional, high-performance standard. You are expected to take full ownership of the electronics lab: organization, tooling, standards, and capability expansion. You should have strong opinions on how things should be built and continuously push
the team toward higher quality and faster execution. This is a critical position where your craftsmanship, speed, and judgment directly impact our ability to execute hardware milestones on aggressive timelines. Key
Responsibilities Build high-reliability wiring harnesses for test systems and subsea deployments Assemble, wire, and debug PLC cabinets and electrical control panels for test infrastructure Perform precision soldering, PCBA rework, and board-level debugging Support bring-up and debugging of electrical systems alongside engineers Read and interpret schematics, wiring diagrams, and system layouts Select connectors, wire types, shielding, and routing strategies appropriate for harsh environments Implement best practices for grounding, EMI mitigation, and signal integrity Maintain and enforce high standards for harnessing, labeling, documentation, and workmanship Own the electronics lab: organization, cleanliness, inventory, and tool readiness Identify gaps in capability and drive procurement of new tools, test equipment, and infrastructure Support rapid prototyping and test readiness under tight timelines Document builds, issues, and fixes clearly for engineering and QA traceability Troubleshoot electrical issues across test systems and deployed hardware Contribute to safe electrical practices across the lab and test environments
