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 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
QUALIFICATIONS
- 5+ years of hands-on experience as an electronics technician, electrical technician, or similar role
- Demonstrated experience building and troubleshooting complex wiring harnesses and electrical systems
- Strong soldering skills including fine-pitch work and PCBA rework
- Experience assembling and wiring control panels, PLC cabinets, or industrial electrical systems
- Ability to read and interpret electrical schematics and wiring diagrams
- Deep practical understanding of connectors, crimping, shielding, grounding, and cable management
- Experience debugging electrical systems using oscilloscopes, multimeters, and other lab equipment
- Strong craftsmanship and attention to detail in physical builds
- Track record of maintaining a clean, organized, and high-functioning lab environment
- High ownership mindset and ability to operate independently with minimal supervision
- Comfortable working in a fast-paced, prototype-driven environment where designs evolve rapidly
- Strong communication skills and ability to work closely with engineers
PREFERRED SKILLS
- Experience with subsea, marine, aerospace, or other harsh-environment systems
- Background as an electrician or experience with high-power electrical systems
- Familiarity with industrial controls, sensors, and data acquisition systems
- Experience with EMI/EMC best practices and debugging
- Ability to perform basic mechanical fabrication to support electrical builds
- Experience setting up and scaling electronics lab infrastructure from scratch
- Familiarity with standards for labeling, documentation, and traceability in high-reliability systems
COMPENSATION, BENEFITS, & PERKS
As a pre-revenue startup, Endurance Energy offers competitive base salaries and generous equity packages for full-time employees. Final base salary will be determined by an array of factors including internal equity, job-related knowledge, skills, and work experience.
A key aspect of our compensation philosophy is that value creation should be aligned with rewards. Right now this means equity is a significant portion of every full-time employee's compensation. As the company matures, there will be continued evolution and changes to the total rewards and total compensation package. What will always be true is that if we win, we win together. Equity is granted to every full-time employee as a meaningful piece of ownership. We believe the people building the company should share directly in the value they create.
In addition to a competitive base salary and equity, employees will receive all of our other great benefits and perks, including:
- Benefits: Health, Dental, and Vision insurance coverage
- Time Away: Flexible PTO including 12 paid company holidays
- Global Fieldwork: Travel to fascinating deployment sites along oceanic ridges in locations like the Pacific Northwest, Hawaii, Iceland, Japan, New Zealand, and the Azores
- Hands-on Experience: Participate in sea trials and deployment operations in partnership with leading oceanographic institutions
- Cutting-edge Development: Work with technology that spans high-power electronics, marine systems, and clean energy
- Impactful Work: Help solve one of the world's most pressing challenges
- Dive Certification: Company-sponsored recreational dive certification
- Other Perks: Access to the company boat, free meals and snacks, and the list goes on!
