Job Description:

The Power / Class-D Amplifier Engineer will design, develop, test, and optimize audio power amplifiers and associated power electronics. This includes Class-D amplifier architecture, circuit design, prototyping, performance validation, and troubleshooting. The ideal candidate has hands-on experience with audio amplifier hardware and power electronics and can work independently in a dedicated home laboratory environment.

Job Duties:

  • Design, develop, and optimize Class-D audio power amplifiers and associated power supply circuits.
  • Develop amplifier schematics, select components, and support PCB design and layout.
  • Perform circuit simulation, design analysis, and engineering calculations to validate proposed designs.
  • Build, test, and validate amplifier prototypes, identifying opportunities to improve performance and reliability.
  • Measure and optimize THD+N, signal-to-noise ratio, frequency response, output power, efficiency, and distortion.
  • Troubleshoot amplifier circuitry, switching power supplies, grounding, noise, EMI/EMC, and thermal issues.
  • Evaluate output stages, gate drivers, feedback networks, protection circuits, and power management solutions.
  • Collaborate with firmware, DSP, mechanical, manufacturing, and quality teams during product development and validation.

Job Requirements:

  • Bachelor’s degree in Electrical Engineering, Electronics Engineering, or a related field.
  • 5+ years of relevant experience in audio electronics, power amplifier design, power electronics, or hardware development.
  • Demonstrated hands-on experience designing or developing Class-D audio power amplifiers.
  • Strong knowledge of analog circuit design, switching power supplies (SMPS), feedback control, and power conversion.
  • Experience with schematic capture, PCB design, circuit simulation, and hardware debugging tools.
  • Proficiency with SPICE-based simulators, Altium Designer, KiCad, or similar engineering tools.
  • Hands-on experience with oscilloscopes, electronic loads, power supplies, and audio measurement equipment.
  • Understanding of EMI/EMC mitigation, thermal management, electrical protection, and product reliability.
  • Excellent analytical, troubleshooting, documentation, and communication skills.
  • Dedicated home laboratory setup with suitable electronic test equipment for prototyping, measurement, and troubleshooting.
