Hardware Engineer (Digital & Analog Circuit Design – AC Mains Systems)

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.

Qualifications :

Required Qualifications

• Bachelors or Masters degree in Electrical Engineering or related field.
• 5 years of experience in digital and analog hardware design.
• Hands-on experience designing circuits powered from AC mains.
• Experience with offline AC-DC power supply design and switching regulators.
• Strong understanding of:
  • High-voltage safety practices
  • Isolation techniques
  • Creepage/clearance requirements
  • EMI/EMC design principles
• Experience with schematic capture and PCB design tools (e.g. Altium OrCAD Cadence KiCad).
• Proficiency in SPICE-based simulation tools.
• Strong hands-on lab debugging skills.
• Working knowledge of regulatory and safety standards for mains-powered equipment.

Preferred Qualifications

• Experience with power factor correction (PFC) design.
• Familiarity with surge immunity and ESD standards.
• Experience participating in UL/IEC certification processes.
• Experience with thermal design and power dissipation analysis.
• Knowledge of embedded firmware interaction and system-level integration.
• Experience supporting products from prototype through mass production.

Key Competencies

• Strong understanding of safe high-voltage design practices
• Analytical and detail-oriented
• Structured problem-solving approach
• Ownership mindset from concept to production
• Effective cross-functional collaboration
