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 Build and test prototypes; develop test plans and validation procedures. Use lab equipment (oscilloscopes, audio analyzers, spectrum analyzers, loads). Perform root-cause analysis and drive corrective actions. Cross-Functional Collaboration Work closely with mechanical, firmware, manufacturing, and quality teams.

Support design for manufacturability (DFM), test (DFT), and cost optimization. Assist with production bring-up and field issue resolution. Essential Tasks Provides support for customer problems/complaints. This could be in-house, telephone, modem, on site, etc. Prepare project cost and work-time estimates. Review existing electrical engineering criteria to identify necessary revisions, deletions or amendments to outdated material.

Plan method and sequence of operations for developing and testing experimental electronic and electrical equipment. Proficiency in the use of electronic test equipment, comprehensive understanding of electronic circuitry theory. Comprehensive understanding of mechanical PCB design for audio and power circuitry.
