Job Description

Position Summary

We are seeking a Hardware Engineer with strong experience in digital and analog circuit design, including systems powered directly from AC mains. This role focuses on the design and development of mixed-signal hardware platforms that interface with high-voltage AC power, convert and regulate power safely, and integrate precision analog and digital control systems.

The ideal candidate has hands-on experience designing offline power supplies, understanding regulatory requirements, and bringing products from concept through certification and production.

Key Responsibilities
  • Design and develop digital and analog circuits for mixed-signal embedded systems.
  • Design circuits operating from AC mains (120/230VAC), including:
    • AC-DC power conversion (flyback, buck, PFC, isolated/non-isolated topologies)
    • Rectification, filtering, and surge protection
    • Inrush current limiting and EMI filtering
    • Isolation strategies (optocouplers, transformers, digital isolators)
  • Design and validate power supply subsystems (LDOs, DC-DC converters, battery backup systems as applicable).
  • Implement protection circuitry (overcurrent, overvoltage, thermal protection, short-circuit protection).
  • Ensure compliance with safety and regulatory standards (UL, IEC, CE, FCC, etc.).
  • Perform creepage and clearance analysis in PCB layout for high-voltage sections.
  • Develop and review PCB layouts with attention to:
    • High-voltage isolation barriers
    • EMI/EMC mitigation
    • Signal integrity and grounding strategies
  • Design analog front ends (AFEs) including amplifiers, filters, ADC/DAC interfaces, and sensor signal conditioning.
  • Integrate microcontrollers and digital interfaces (SPI, I2C, UART, USB, Ethernet as applicable).
  • Conduct circuit simulations (SPICE) and worst-case/tolerance analysis.
  • Develop and execute hardware validation and compliance test plans.
  • Troubleshoot and debug boards using oscilloscopes, differential probes, current probes, isolation transformers, and other lab instrumentation.
  • Support product certification testing and manufacturing ramp.
  • Create thorough design documentation and support DFM/DFT reviews.
