Hardware Design Engineer

We are looking for an experienced Electronics Hardware Design Engineer to develop PCB designs for charge controllers used in EV chargers and power management systems. The ideal candidate will have expertise in high-speed PCB design, CAN communication, and other serial interfaces. This role involves schematic design, PCB layout, prototyping, and testing, ensuring compliance with industry standards.

KEY RESPONSIBILITIES

1. Hardware Design & PCB Development:

• Design schematics and multilayer PCBs for EV charge controllers using tools like Altium Designer, KiCAD.
• Optimize PCB layouts for power handling, EMI/EMC compliance, thermal management, and signal integrity.

2. Communication Interfaces & Protocols:

• Integrate CAN (Controller Area Network), UART, RS-485, SPI, and I2C for reliable data exchange.
• Develop robust communication bus architectures for real-time monitoring and control of charge controllers.

3. Power & Analog Circuit Design:

• Implement current sensing (shunt, Hall sensors), RCD (Residual Current Device), and fault detection mechanisms.
• Design DC-DC converters, SMPS, power monitoring circuits, and charger protection systems.

4. Prototyping, Testing & Validation:

• Conduct PCB bring-up, debugging, and hardware validation using oscilloscopes, logic analyzers, and network analyzers.
• Perform EMI/EMC testing, surge protection testing, and thermal analysis.

5. Compliance & Safety Standards:

• Ensure PCB designs meet IEC, UL, and ISO safety standards for EV charging applications.
• Implement ESD protection, isolation techniques, and regulatory compliance in hardware designs.

6. Collaboration & Documentation:

• Work with cross-functional teams (firmware, mechanical, and power electronics engineers) to ensure seamless system integration.
• Prepare detailed design documentation, BOM (Bill of Materials), and test reports.

REQUIRED QUALIFICATIONS

• Education: Bachelor's/Masters in Electronics Engineering, Electrical Engineering, or Embedded Systems.
• Experience: 0-6 years in hardware design, PCB development, and EV charger electronics (preferred).
• PCB Design Tools: Altium Designer, KiCad, Eagle, ORCAD, PADS, etc.
• Communication Protocols: CAN, CAN FD, UART, SPI, I2C, RS-485, MODBUS.
• Power Electronics: Experience with DC-DC converters, SMPS, surge protection, relays/contactors.
• Testing & Debugging: Hands-on experience with oscilloscopes, multimeters, CAN analyzers, EMI/EMC compliance testing.
• Experience in EV charging systems (AC/DC chargers, OCPP integration).
• Familiarity with microcontrollers (STM32, TI, NXP) and real-time systems.
• Hands-on experience with thermal management and reliability testing.
