Power Electronics Engineer Jobs in Miami, FL (NOW HIRING)

We are looking for a Lead Power Electronics Engineer to lead development of Exowatt’s next-generation MW-class multi-port power conversion solution. This person will own system architecture, product and engineering requirements, partner evaluation, development oversight, validation, and certification readiness for a high-power solution using advanced technologies such as SiC, GaN, and/or Solid State Transformer architectures.

This is a senior technical role for someone who has designed, developed, or brought up power conversion systems at the hundreds-of-kW to MW scale. The ideal candidate has practical experience with high-power converter design, grid-interactive systems, controls integration, protection, thermal and mechanical design, EMI/EMC, safety, and certification.

The person in this role will work closely with product, systems, controls, firmware, mechanical, thermal, manufacturing, supply chain, and external development partners to bring a robust MW-level multi-port solution to certification readiness by Q4 2027.

• B.S., M.S., or Ph.D. in Electrical Engineering, Power Electronics, Power Systems, Controls, or a related field

• 10+ years of experience in power electronics, high-power converter development, grid-interactive systems, or advanced energy systems

• Demonstrated experience with power conversion systems in the hundreds-of-kW to MW range; direct MW-class converter experience strongly preferred

• Strong hands-on experience with SiC-based power conversion; GaN experience preferred

• Experience leading high-power electrical products from concept through prototype, validation, and certification or production readiness

• Deep understanding of converter topologies, semiconductor switching behavior, gate drivers, magnetics, DC link design, busbars, protection, filtering, EMI/EMC, and thermal constraints

• Experience developing product requirements, engineering requirements, system specifications, test plans, validation plans, and certification-readiness documentation

• Strong understanding of high-voltage and high-power safety, including isolation, creepage/clearance, grounding, fault containment, arc flash considerations, and lab safety practices

• Ability to evaluate system-level tradeoffs across performance, cost, reliability, manufacturability, scalability, certification complexity, and time-to-market

• Excellent technical communication skills with the ability to influence architecture decisions and align technical and non-technical stakeholders

• Experience with Solid State Transformers, multi-port converters, modular converters, medium-voltage power conversion, or high-power isolated DC/DC architectures

• Development of MW-class inverters, converters, rectifiers, UPS systems, EV fast charging systems, BESS power conversion systems, solar inverters, wind converters, industrial drives, or medium-voltage power electronics

• Experience with grid-tied systems, renewable energy systems, energy storage, data center power, DC microgrids, or hybrid energy systems

• Familiarity with grid-forming, grid-following, droop control, black start, synchronization, fault ride-through, harmonic control, and power quality requirements

• Experience with SiC MOSFET modules, GaN devices, advanced gate drivers, laminated busbars, high-frequency magnetics, and high-power capacitor banks

• Familiarity with simulation tools such as MATLAB/Simulink, PLECS, PSCAD, PSIM, LTspice, SPICE-based tools, or equivalent platforms

• Experience with NRTL/certification labs and standards such as UL 1741, UL 1973, UL 9540, UL 2202, IEEE 1547, IEC 62477, IEC 61000, IEC 61800, or related high-power product standards

• Experience working in a startup or fast-moving hardware product development environment

The right candidate has real MW-class power electronics experience, not just simulation or low-power design experience. They can compare SiC, GaN, Solid State Transformer, modular, isolated, and transformer-based architectures and make practical tradeoffs across performance, cost, reliability, certification, manufacturability, and schedule.

They are comfortable moving from product requirements to engineering requirements, from architecture to prototype, and from test data to root-cause analysis. They also know how to evaluate external partners and hold them accountable while helping Exowatt build strong internal technical capability.
