We are seeking a detail-oriented and experienced PCB Layout Engineer to join our power electronics R&D team. You will focus on the physical design of PCBs (including control boards, power supply boards, and high-power boards) for various power electronic products in new power distribution systems. You will be a critical link in achieving high performance, reliability, and manufacturability, directly impacting the product's electrical performance, thermal management, and EMC performance.

Key ResponsibilitiesPCB Physical Design:

• Independently complete the layout and routing of multi-layer boards based on design specifications provided by hardware engineers.
• Responsible for designing all types of PCBs, including control boards (high-speed digital/analog signals), power supply boards (medium power), and high-power boards (high voltage, high current).

Collaborative Design & Rule Definition:

• Work closely with hardware engineers to understand and interpret requirements, and jointly define detailed PCB layout and routing constraint rules.
• Provide optimal placement and routing strategies considering safety, signal integrity, power integrity, and thermal management requirements.

Power Electronics-Specific Design:

• Power Loop Design: Optimize the layout of high-voltage and high-current paths to minimize parasitic inductance and loop area.
• EMC & Safety Design: Strictly ensure creepage and clearance distances in the layout; enhance EMC performance by optimizing ground planes, shielding, and filter placement.
• Thermal Design: Design effective thermal dissipation paths for power devices and heat-generating components, including thermal pads, via arrays, and interface coordination with heat sinks.
• Signal Integrity: Ensure the integrity of critical sensitive signals (e.g., sampling, gate drive signals) and avoid interference.

Design Output & Documentation:

• Generate all necessary production files (Gerber, drill files, assembly drawings, solder paste stencil files, etc.).
• Create and maintain component footprint libraries, ensuring their accuracy and manufacturability.
• Prepare PCB layout design documentation.

Design Verification & Support:

• Participate in PCB design reviews; support SI/PI/thermal simulation engineers in pre-layout and post-layout simulations.
• Assist in resolving PCB-related technical issues encountered during prototyping, mass production, and testing.

• Design Tools: Proficiency in mainstream EDA design tools such as Cadence Allegro.
• Professional Knowledge: Deep understanding of PCB manufacturing processes (lamination, hole plating, surface finishes, etc.) and SMT assembly processes.
• Electrical Knowledge: Familiarity with IPC standards; solid fundamental circuit knowledge and the ability to understand schematics.
• Specialized Skills: In-depth understanding of layout and routing for high-speed digital, analog, power, and RF circuits; ability to independently solve related SI, PI, EMC, and thermal design issues.

Personal Attributes:

• Strong sense of responsibility, patience, and a meticulous, rigorous work attitude.
• Excellent communication skills and teamwork spirit, enabling effective collaboration with hardware engineers.
• Strong problem-analysis and problem-solving abilities, with the capacity to work under pressure.

Preferred Qualifications

• Familiarity with common safety standards for power electronics products (e.g., UL 60950-1, UL 1741) and their requirements for PCB layout.
• Priority given to candidates with experience seeing PCB design projects through their complete lifecycle.
