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.

  • 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...
