Power Supply & Audio Amplifier Engineer

The Position

The Power Supply & Audio Amplifier Engineer designs, develops, and validates high-performance power and audio circuits for commercial, industrial, or OEM products. The position will blend deep analog expertise with practical, hands-on engineering.

This role is hybrid, requiring 3 days per week in the office, and 2 days remote.

We are looking for qualified candidates in the Elkhart, IN market.

Essential Functions

• Power Supply Design

  • Design and optimize AC-DC and DC-DC power supplies, including linear and switching topologies.
  • Perform schematic capture, simulation, component selection, and PCB layout review.
  • Address efficiency, thermal performance, EMI/EMC, safety, and reliability requirements.
  • Support compliance testing (UL, CE, FCC, etc.)

• Audio Amplifier Design

  • Design and develop audio amplifier circuits (Class A, AB, D, or hybrid).
  • Optimize audio performance: THD+N, SNR, frequency response, stability, and efficiency.
  • Select and evaluate audio ICs, power devices, magnetics, and passive components.
  • Troubleshoot noise, distortion, grounding, and layout-related issues.

• Prototyping & Validation
