Rilear Industries is a category-defining, defense-forward startup that is establishing persistent underwater autonomy. We are building the underwater infrastructure that untethered assets need to stay down and stay useful.
The battlefield is increasingly moving subsea, and amid rising geopolitical tension, advancing these capabilities has never been more urgent. Our focus is informed by real operating experience in the U.S. Navy, and our co-founding team combines subsea robotics, power systems, and Navy expertise, with backgrounds from Harvard, Carnegie Mellon, and Georgia Tech.
You will own the electrical design of our subsea power and data transfer system end to end: from the topology through to a pressure-qualified, wet-tested unit deployed at sea.
You will make the architectural calls, build the hardware yourself, take it in the water, find out what broke, and iterate. You will report to our CTO and work closely with our CEO. This is a small team, and your decisions will shape the product and the company.
- Architecture end to end: transfer method, operating frequency, converter topology, and the loss and efficiency budget from source bus to load battery.
- Interface design and FEA (Maxwell/COMSOL) for transfer efficiency, AC and conduction loss, and current and field distribution across the full misalignment envelope, including loss into the surrounding seawater.
- Materials, sealing, and corrosion behavior at the wet interface.
- Power electronics from front-end conversion and drive stage through synchronous rectification, protection, and thermal design in sealed housing.
- One-way telemetry alongside the power transfer: modulation, link budget, and keeping converter switching noise out of the data channel.
- Test the tech in the lab and in the field.
- Deep expertise moving kW-class power across a physical interface: resonant/inductive WPT, high-power direct-contact systems, or both.
- FEA and circuit simulation (Maxwell, COMSOL, or equivalent).
- Full-cycle hardware ownership through layout, bring-up, and debug; strong lab instincts.
- Strong PCB design fundamentals.
- Willingness to travel for sea trials.
This role requires U.S. person status and is subject to export control requirements.
Rilear Industries is an equal opportunity employer.
