Job Description

Role Summary (P17)

The PCB Layout Engineer is responsible for designing multi-layer PCB layouts for power electronics hardware such as AC-DC rectifiers, DC-DC converters, inverters, onboard/offboard chargers, SMPS, gate drivers, and control boards.

The role focuses on high-power, high-voltage, high-frequency layout, ensuring thermal performance, EMI/EMC compliance, safety isolation, and manufacturability.

Key Responsibilities

1. PCB Layout Design (High Voltage / High Current / High Frequency)

- Design multi-layer PCBs (2–12+ layers) for:
– Power stages (MOSFET/IGBT/SiC/GaN)
– Gate driver boards
– HV/LV sensing circuits
– Digital controller boards (MCU/DSP)
– Auxiliary power supplies
- Optimize layout for:
– Low loop inductance
– Controlled impedance traces
– Creepage & clearance for HV designs
– Short gate loops and Kelvin source routing
– High current copper thickness and pours

2. EMI/EMC-Optimized Layout

- Apply best practices for:
– Minimizing switching noise
– Grounding strategy (AGND/DGND/PGND separation)
– Shielding and filtering
– Common-mode noise control




– Differential pair routing (CAN, LVDS, Ethernet)

3. Thermal & Mechanical Considerations

- Design layouts supporting:
– Heat spreading
– Thermal relief, thermal vias
– Heatsink and busbar interface
– Component derating and spacing

- component supports & PCB mounting considering vibration/shock

- Work with mechanical team for 3D integration.

4. Compliance & Safety Layout

- Ensure PCB meets:
– Creepage/clearance per IEC/UL standards
– Insulation requirements for HV (>800 Vdc)
– Automotive or industrial safety rules
- Design as per IPC/IEC standards
- Design isolation barriers with proper spacing and cut-outs.

5. Design for Manufacturability (DFM) & Assembly (DFA)

- Apply DFM/DFA rules with PCB fabs and assemblers.
- Prepare fabrication files Gerber/ODB++, Drill files, Stack-up, Mask files, Assembly drawings, Pick & place data
- Generate 3D models of the PCB
- Perform /coordinate Signal integrity and Power Integrity Analysis

6. Library & Documentation Management

- Create and maintain symbols, footprints, and 3D models.
- Maintain layout documentation, revision control, and release notes.

7. Cross-Functional Collaboration

- Work with:
– Power Electronics/ Hardware circuit designers
– Embedded/control engineers




– Mechanical engineers
– Manufacturing and quality teams
- Participate in design reviews (DR0/DR1/DR2/DFM review).

Required Skills & Qualifications

Technical Skills
