Jobs at Endurance

Responsible for planning and executing complex integration and test campaigns for subsea energy hardware, collaborating across teams to ensure reliable field deployments and operational readiness.

Design and own subsea power conversion and distribution systems from concept to offshore deployment. Responsibilities include topology selection, magnetics and high-power PCBA design, layout and EMI/thermal control, protection strategy, lab bring-up, validation testing, failure analysis, production release, and cross-functional integration with mechanical, controls, and offshore teams.

In this role, you will design, build, and maintain electrical systems for subsea geothermal power plants, focusing on high-quality harnesses and debugging.

Own the general ledger and audit readiness, review monthly close produced by an outsourced firm, run balance sheet reconciliations, manage accounting policies and CFO/board reporting, support payroll and vendor setup, lead NetSuite migration and consolidation, and prepare controls for audits, investors, and lenders.

Assemble, plumb, instrument, and test complex mechanical and fluid systems to create pressure-tight, leak-free, instrumented hardware. Perform tubing/piping integration, install sensors, execute pressure and leak testing, support system bring-up and debugging, document builds and ensure safe repeatable processes to meet aggressive hardware milestones.

Owns policy, permitting, environmental, and external-affairs workstreams for subsea geothermal energy projects. Responsibilities include tracking legislation and agency actions, drafting regulatory materials, supporting NEPA and permitting processes, coordinating technical contributors, managing consultants and counsel, preparing executives for stakeholder engagements, pursuing government funding, and representing the company in Washington. The role requires regular travel to Seattle and periodic travel to international deployment sites.

Build and maintain test infrastructure for subsea geothermal systems: design HITL/SITL simulations, automated test frameworks, DAQ/PLC/VFD integration, data acquisition and visualization, and hands-on lab validation. Partner with cross-disciplinary engineers to scale test systems from component rigs to full system validation and help shape the growing test infrastructure team.

Endurance Energy is seeking technically excellent engineers to work on clean energy systems. Responsibilities include hands-on work with large-scale systems and contributing to power generation solutions.

The Senior Mechanical Engineer will design hardware for seafloor geothermal plants, creating systems that endure harsh conditions, leading the complete development from concept to deployment.

Lead design, analysis, and optimization of high-speed turbines and pumps for compact power cycles. Perform 1D/2D sizing, high-fidelity 3D CFD and structural FEA, testing and validation, rotor and seal integration, and develop internal modeling processes and standards to scale production and subsea deployments.
