Power Electronics Engineer | High Power | Contract
Port Jefferson, New York
Contract | Flexible Structure | On-Site Regularly

Are you a

Power Electronics Engineer

who has designed, built and tested high-power converters? Have you worked with

10–100kW systems, 270–800V DC, PFC or DC-DC conversion ? Would you be interested in a flexible contract where your expertise can immediately help solve challenging power electronics problems? If so, this opportunity may be the right next step for you.

This aerospace and defense organisation is developing advanced power conversion hardware and needs an experienced contractor who can contribute quickly. You'll work directly with the engineering team, getting into the actual hardware rather than operating purely as an advisor.

The

Power Electronics Engineer

will support the design, development and troubleshooting of aerospace power converters operating below 1kV, with particular focus on

10–100kW power levels and 270–800V DC architectures .

As the Power Electronics Engineer your responsibilities will include
Designing and developing

high-power converters

from requirements through hardware validation
Evaluating

PFC, DC-DC and other converter topologies , switching approaches and control loops
Designing and reviewing

transformers, inductors, EMI filter chokes and power magnetics
Supporting

schematic capture, PCB development, prototype bring-up, debugging and testing
Troubleshooting existing hardware and providing practical engineering solutions to accelerate development

As the Power Electronics Engineer you will bring
Hands-on experience designing, building and testing

power converters or power supplies
Experience with

10–100kW systems, 270–800V DC or comparable high-power applications
Strong knowledge of

PFC, DC-DC conversion and power electronics fundamentals
Experience with

SiC/GaN devices, power magnetics, schematic or PCB-level development
Practical experience taking real hardware through

prototype, bring-up, test and troubleshooting

Experience with

EMI filters, conducted-emissions testing, PLECS, LTspice, Ansys Maxwell, MIL-STD-461, MIL-STD-704 or DO-160

would be particularly valuable.

Aerospace experience is

not essential . Engineers from EV, automotive, industrial power, energy, semiconductor equipment, space and defence environments are encouraged to apply.

The

Power Electronics Engineer

will be brought in for technical impact: understanding difficult problems quickly, improving designs and helping get hardware successfully through build and test.
For an experienced contractor or consultant who still enjoys

designing, debugging and getting on the bench , this offers challenging hardware, direct access to the engineering team and a flexible engagement without the commitment of a permanent move.

All successful applicants will be contacted within two working days
