You will own specific electromechanical hardware end to end, including electronics cooling, enclosures, busswork, connectors, actuators, and mechanisms. You will design, build, test, and deploy hardware for subsea geothermal power plants.
What you will do
- Own specific electromechanical hardware end to end
- Design high-power electrical interfaces
- Design subsea packaging for high-power electronics
- Design electronics cooling and thermal management
- Design subsea actuators, motors, pumps, and mechanisms
- Translate electrical requirements into mechanical designs
- Design and build test setups for high voltage under hydrostatic pressure
- Lead root-cause investigations on failures and implement corrective actions
- Define interfaces with valves and primary structures
- Work with machine shops, molders, and specialty suppliers
Required qualifications
- Bachelor's degree in mechanical engineering, electrical engineering, or a related engineering discipline
- 6+ years of professional experience designing electromechanical hardware for demanding environments
- Ownership of at least one electromechanical component from concept through qualification and fielded use
Nice to have
- Experience designing subsea electrical connectors, penetrators, busswork, or actuators, or equivalent experience with spacecraft mechanisms, downhole tools, or power electronics packaging for aerospac
- Hands-on experience with dielectric fluids, pressure compensation, and sealing high voltage against seawater
- Experience with dynamic and rotating seals, magnetic couplings, and the failure modes of mechanisms in long-duration service
- Experience with thermal management of power electronics, including liquid- or immersion- cooled systems
- Working knowledge of high-voltage design and test: creepage and clearance, insulation resistance, partial discharge
- Experience sizing motors and actuators and integrating electronics into mechanical assemblies
- Experience at a small or fast-moving hardware organization
- A track record of taking on increasing responsibility and delivering something difficult early in your career
- Experience on an engineering competition team (Formula SAE, Baja SAE, RoboSub, rocketry, or similar) or an equivalent self-directed hardware project
Benefits
- Health, Dental, and Vision insurance coverage
- Flexible PTO including 12 paid company holidays
- Travel to deployment sites along oceanic ridges
- Participate in sea trials and deployment operations
- Company-sponsored recreational dive certification
- Access to the company boat
- free meals and snacks
