High-Speed Digital PCB Layout Engineer Responsibilities Advanced Signal Integrity (SI) Management Impedance Control: Calculate and implement controlled impedance for single-ended and differential signals based on dielectric materials and stackup. Length & Phase Matching: Execute precise delay tuning and "snake" routing for high-speed buses (DDR4/5, PCIe Gen 4/5, USB4) to meet strict setup and hold time requirements. Topology Execution: Implement complex routing topologies including Fly-by, T-topology, and Point-to-Point for multi-drop memory interfaces. Physical Design & Stackup Architecture Stackup Definition: Collaborate with fabrication houses to define layer counts, copper weights, and specialized materials (e.g., Megtron 6, Rogers) to minimize insertion loss. Constraint Management: Set up and manage thousands of high-speed design rules within the EDA constraint manager to automate error checking. Micro-Via Strategy: Utilize stacked and staggered micro-vias, blind/buried vias, and via-in-pad technology for 0.4mm and 0.5mm pitch BGA components. Power Integrity (PI) & Thermal Design Plane Design: Design solid, low-inductance power and ground planes to provide stable voltage to CPUs, FPGAs, and ASICs. Decoupling Optimization: Optimize the placement of decoupling capacitors to minimize the loop inductance of the PDN. Thermal Relief: Work with mechanical engineers to place high-power components and thermal vias to prevent localized "hot spots" on the board. Qualifications MSc or PhD in Electrical Engineering, Electronics Engineering. 5+ years of experience in electronic hardware design, with a strong focus on high-speed digital circuits. Experience in circuit simulation tools is highly valued. Strong understanding of signal integrity and power integrity concepts. Experience with high-speed interface design and testing. Familiarity with industry standards and regulatory compliance (e.g., EMC). Excellent problem-solving and analytical skills. Strong communication and teamwork skills. What Distinguishes You Strong experience and knowledge with PCB layout design tools such as Xpedition, Altium, or equivalent tools. Good experience with circuit design simulator software packages such as HyperLinx, PSPICE, LTSpice, or equivalent simulation tools. Experience in MedTech and/or aerospace industries is highly valued. Languages: fluent in English, other languages are a plus. Stay up-to-date with the latest technologies and industry trends.
