About the Company The open ocean is Earth’s largest and most power-dense renewable energy resource. Panthalassa is harnessing that resource to generate the cheapest energy on the planet. Our mission is to provide abundant and affordable clean energy for everyone.

We are rapidly scaling our capacity to test megawatts of compute and hydroelectric turbines while bringing online state-of-the-art manufacturing equipment across multiple sites. In this environment, identifying creative, practical solutions that enable the delivery of sufficient power—quickly and reliably—will be a key contributor to the company’s success. Founded in 2016 and based in the Pacific Northwest, our team comes from diverse backgrounds in aerospace, naval architecture, marine operations, hardware, software, and research.

About the Job We are building a core technology designed to operate in the harshest, most unpredictable environments on Earth, the world’s oceans. Delivering on this mission requires not only elite engineering talent but a work environment that runs smoothly, scales intelligently, and frees our team to focus on solving impossibly hard problems. We are looking for a reliable and skilled Facilities Maintenance Technician to support the day-to-day upkeep of an active facility.

This is a steady-state role focused on keeping the site safe, functional, and well-maintained — handling routine maintenance, minor repairs, and the essential day-to-day work that keeps facility operations reliable and uninterrupted. You'll work across a variety of tasks and systems, so range matters, but so does consistency and attention to detail. This role supports a mixed office and light industrial environment with active daily operations, shared workspaces, and evolving operational needs.

The work is highly hands-on and operational, requiring both technical maintenance capability and responsiveness to employee and facility needs. You're the person who notices something is off before anyone else reports it. You close out tickets thoroughly with clear notes, communicate proactively when something is outside your scope, and take pride in a facility that functions the way it's supposed to.

The work is varied and highly operational — adaptability matters. Some days may focus on preventive maintenance and repairs, while others may involve workspace resets, operational support, or rapid-response facility issues during high-intensity work periods. What You’ll Own Facility Operations & Infrastructure Perform routine corrective maintenance across the facility, including minor repairs to fixtures, furniture, hardware, and light mechanical and electrical systems.

Execute preventive maintenance schedules, inspections, and equipment servicing activities to maximize reliability and reduce unplanned downtime. Support the safe operation of building systems including electrical, HVAC, plumbing, and compressed air, escalating to vendors or specialists when issues exceed scope. Troubleshoot and perform minor repairs on plumbing systems including fixtures, valves, toilets, drains, water heaters, and leak investigations.

Perform minor electrical troubleshooting and repairs including lighting, receptacles, switches, breakers, motors, disconnects, and low-voltage control systems within applicable licensing and scope limitations. Maintain and troubleshoot mechanical systems including pumps, fans, blowers, compressors, motors, gearboxes, belts, bearings, chains, and drive components. Support pneumatic and compressed air systems including regulators, valves, filters, air dryers, and distribution equipment.

Monitor infrastructure reliability and flag emerging issues before they become larger problems. Conduct routine inspections of mechanical rooms, electrical rooms, roof-mounted equipment, utility infrastructure, and facility support systems.
