Senior Electronics Technician

About Endurance

Endurance is building the worlds first modular subsea geothermal power plants converting vast thermal resources under the ocean into gigawatts of baseload power. Backed by 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 our generation pilot this year. By leveraging 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 youll be doing

As a Senior Electronics Technician 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.
