Power Electronics Engineer — Underwater Maritime Systems

Great Bay Staffing Group•Concord, MA

9d•Hybrid

About The Position

This role involves designing and building power electronics for underwater maritime systems, including unmanned underwater vehicle payloads, electromechanical actuation systems, acoustic communication transceivers, and high-power acoustic transmit arrays. It is a hands-on R&D position where designs progress from schematic to prototype to ocean-ready hardware. The engineer will collaborate with other engineers, scientists, and customers in a small-team environment focused on technical excellence and innovation.

Requirements

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.

Nice To Haves

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.

Responsibilities

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%).
