Power Electronics Engineer — Underwater Maritime Systems

Concord, MA or Groton, CT

$140,000–$180,000 + Full Relocation + Top Benefits & 401(k)

You will design and build the power electronics that drive underwater maritime systems — from unmanned underwater vehicle payloads and electromechanical actuation systems to acoustic communication transceivers and high-power acoustic transmit arrays. This is hands‑on R&D work where your designs move from schematic to prototype to ocean‑ready hardware. You will collaborate directly with engineers, scientists, and customers in a small‑team environment where technical excellence and innovation are the priority.

• Work across a wide variety of multidisciplinary programs spanning cutting‑edge underwater technologies
• Small company environment with direct collaboration alongside colleagues and customers who value creativity
• Full relocation assistance provided
• Competitive compensation with top‑tier benefits and 401(k)

• Design, develop, integrate, and debug complex power electronics systems including DC/DC and AC/DC converters, power amplifiers, magnetics, and energy storage components ranging from 500W to 50kW
• Select components, capture schematics, design PCBs, and run verification testing for harsh underwater operating environments
• Interface power systems with embedded processors and integrate high-power components into larger system architectures
• Troubleshoot electronic systems using oscilloscopes, DMMs, function generators, and digital measurement probes
• Travel to support on‑site testing (up to 25%)

Required:

• B.S. in Electrical Engineering with a concentration in power systems
• BSEE with 4+ years of relevant experience, or MSEE with 1+ years of relevant experience
• Proven track record designing, implementing, and testing high‑voltage/high‑power electrical components for prototype R&D systems
• Experience with high availability power supplies and/or failover systems
• Comprehensive knowledge of power devices including MOSFETs, Schottky Diodes, SiC FETs, and IGBTs
• Hands‑on experience with electromechanical actuators, DC/DC converters, power amplifiers, and magnetics
• Basic MATLAB‑aided data analysis skills
• Proficiency with standard electronic lab test equipment

Preferred:

• Experience designing electronics for underwater maritime systems or acoustic transducers
• Familiarity with power converter topologies (buck, boost, flyback, SEPIC) and their control methods
• Experience designing electric machines and/or drives
• PCB layout experience or vendor management for board layout
• EMC design and high‑power system integration experience
• C/C++ or Python coding for microcontrollers or embedded platforms
• Experience mentoring junior engineers and briefing customers
• Background in R&D environments and small multidisciplinary teams
