We are looking for a highly motivated Power Electronics Engineer to join our Sensing and Communications Department in Concord, MA or Groton, CT. Successful candidates will have a BS, MS, or PhD in Electrical Engineering with a focus in power systems design. You will support the design and development of a wide variety of underwater maritime systems including electromechanical actuation systems, payloads for unmanned underwater vehicles, acoustic communication transceivers, motor systems, and high-power acoustic transmit arrays. Candidates must have a proven track record of designing, implementing, and testing high voltage/high power electrical components of prototype R&D systems. Experience designing energy storage system components, DC/DC converters, power amplifiers and magnetics, and interfacing with embedded processors is required. Previous experience laying out boards and/or managing layout vendors is highly desired, as is experience designing for EMC and integrating high power components into larger systems.
Job Responsibility:
Design, development, integration, and debugging of complex power electronics systems
Travel to support on-site testing (up to 25%)
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
Experience with power system design: circuit analysis and simulation, component selection, schematic capture, PCB design, and verification testing
Design of DC/DC and AC/DC power systems ranging from 500W to 50kW for harsh operating environments
Experience with high availability power supplies and/or failover systems
Comprehensive knowledge of electronic power devices including MOSFETs, Schottky Diodes, SiC FETs, and IGBTs
Proven experience designing with electromechanical actuators, DC/DC converters, power amplifiers, and magnetics
Experience troubleshooting electronic systems
Basic understanding of MATLAB-aided data analysis
Proficiency with electronic laboratory test equipment: DMM, oscilloscope, function generator, digital voltage and current measurement probes
Experience or familiarity with electronics assembly, wiring, crimping, and soldering is a plus
Nice to have:
Prior experience designing electronics for underwater maritime systems
Prior experience designing electric machines and/or drives
Experience working with acoustic transducers
Familiarity with power converter topologies (buck, boost, flyback, SEPIC, etc.) and their control methodologies
Experience with or oversight of electronic layout, bill-of-materials, and assembly processes
Experience creating technical content for new products, proposals, or business development pursuits
Experience working in an R&D environment and in small multidisciplinary teams
Experience mentoring junior EE staff on electronics design, PCB implementation, and board troubleshooting
Experience briefing customers
Experience with C/C++ or Python coding for microcontrollers or similar embedded platforms
