Staff Power Electronics Engineer

Overview

The Power Electronics Engineer is responsible for creating and implementing electronic hardware products for QSC. The Engineer will design and develop audio specific power supplies and amplifiers with power levels ranging from several watts to tens of kilowatts. A successful candidate needs a broad technical background designing, simulating, fabricating, and testing both switch mode power supplies (SMPS) and class D audio power amplifiers.

Typical responsibilities include analog and digital circuit design, architectural design, schematic capture, circuit modeling and simulation, PCB layout, timing and signal integrity analysis, components evaluation and selection, solving EMC and regulatory issues, bringing up prototypes and troubleshooting, test and validation of the designs.

Engineer is responsible for delivering product design that meets all safety, regulatory, and performance requirements. In addition, the QSC Power Electronics Engineer will provide guidance to junior team members and technicians.

The position requires the individual to work well within a small, cross-functional team consisting of mechanical, software, and firmware engineers, as well as product managers, program managers, manufacturing engineers, and NPI engineers. The role requires someone who is self-motivated, has excellent problem-solving skills, possesses a keen attention to detail, works well within a small team, and can produce results.

Base Salary Range 132,000 - 190,000

The above reflects the pay range that QSC reasonably expects to pay for this role. This pay range also depends on various factors such as job duties and requirements, relevant experience and skills and geographic location. In addition to the base salary range, QSC offers a comprehensive package including but not limited to health benefits, 401K or Roth retirement plans and generous time off.

We will be accepting applications until a final candidate is identified.
