PCB Layout Engineer
Fremont CA (Onsite)
Key Responsibilities
- Own the end-to-end PCB layout process for complex, high-density server and compute boards.
- Develop high-speed PCB layouts supporting DDR4/DDR5, LPDDR5, HBM, PCIe Gen5/Gen6, USB 3.2+, and other high-speed interfaces.
- Apply controlled impedance routing, length matching, differential pair routing, and crosstalk mitigation techniques.
- Design multilayer HDI PCBs utilizing blind, buried, and microvia technologies.
- Collaborate with electrical engineers to review schematics, optimize component placement, power distribution, and signal integrity.
- Work closely with mechanical engineers to resolve board outline, connector placement, thermal, and enclosure constraints.
- Create and maintain PCB stack-ups, design rules, constraint files, and footprint libraries using Cadence Allegro Constraint Manager (CES).
- Conduct Design for Manufacturability (DFM), Design for Assembly (DFA), and Design for Test (DFT) reviews with fabrication and manufacturing partners.
- Support prototype bring-up by providing layout documentation, net tracing, ECO implementation, and design revision analysis.
- Ensure PCB layouts meet performance, quality, manufacturability, and reliability requirements.
Required Qualifications
- Bachelor's degree in Electrical Engineering, Electronics Engineering, or a related field.
- 10–14 years of PCB layout and CAD experience.
- Strong expertise with Cadence Allegro PCB Designer 23.1 or later.
- Extensive experience designing high-speed, high-density PCBs for server or compute hardware.
- Hands-on experience with HDI technology, including blind, buried, and microvias.
- Strong understanding of high-speed interfaces including DDR4/DDR5, LPDDR5, HBM, PCIe Gen5/Gen6, USB 3.2+, Ethernet, and other high-speed protocols.
- Experience with Constraint Editor (CES) and constraint-driven PCB design methodologies.
- Strong knowledge of PCB stack-up development, power integrity (PI), signal integrity (SI), controlled impedance, and differential routing.
- Experience with DFM, DFA, and DFT principles for high-volume manufacturing.
- Excellent communication, collaboration, and problem-solving skills.
Preferred Qualifications
- Experience designing Intel-based server motherboards or complex SoC/FPGA platforms.
- Experience working on AI, data center, networking, telecom, or high-performance computing hardware.
- Familiarity with SI/PI analysis tools and PCB fabrication processes.
- Experience supporting prototype builds through production release.
