Signal Integrity Engineer

Responsibilities

• Design and validate high-speed signal paths for digital and analog interfaces
• Perform 2D/3D simulations including S-parameters, eye diagrams, crosstalk, and impedance control
• Conduct lab measurements using TDR and VNA and develop custom test fixtures
• Collaborate with hardware, layout, and system engineering teams on board design and stack-up
• Evaluate and model component-level behavior using Touchstone files
• Drive design decisions balancing performance, manufacturability, and cost
• Support signal integrity across complex PCBAs, connectors, flex circuits, and cabling

Requirements

• 5 to 20+ years of experience in high-speed signal integrity engineering
• Strong background in PCB signal integrity for on-board and off-board transmission
• Proficiency in ADS, ANSYS HFSS, Sigrity, and Allegro or similar ECAD platforms
• Experience with single-ended and differential signaling up to 50Gbps (NRZ and PAM4)
• Deep understanding of PCB design fundamentals, crosstalk, impedance, and loss modeling
• Skill in generating and analyzing eye diagrams in time and frequency domains
• Familiarity with PCB stack-up design, fabrication limitations, and high-frequency materials
• Hands-on experience with flex circuit design, ribbon cables, coax, and board-to-board connectors

Preferred Qualifications

• Master’s Degree in Electrical Engineering
• Experience leading design reviews or acting as a technical mentor
• Exposure to hardware platform development for networking or data center products
• Strong communication skills for working with cross-regional teams
