Signal Integrity Engineer

About the role

We are looking for experienced Signal Integrity Engineers to join a leading hardware engineering team developing next‑generation networking, server, and storage technologies. The position is permanent and on‑site in either Richardson, TX or San Jose, CA.

Key responsibilities

• Design and validate high‑speed signal paths for digital and analog interfaces on complex multi‑layer PCBs.
• Perform 2D/3D simulations such as 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 teams on board stack‑up, component modeling, and connector selection.
• Drive design decisions that balance performance, manufacturability, and cost.

Required profile

• 5–20+ years of high‑speed signal integrity engineering experience.
• Strong background in PCB signal integrity, both on‑board and off‑board transmission.
• Proficiency with ADS, ANSYS HFSS, Sigrity, Allegro or similar ECAD platforms.
• Experience with single‑ended and differential signaling up to 50 Gbps, including NRZ and PAM4.
• Hands‑on experience with flex circuits, ribbon cables, coaxial interconnects, and board‑to‑board connectors.

Required skills

• ADS
• ANSYS HFSS
• Sigrity
• Allegro (or equivalent ECAD)
• TDR and VNA measurement techniques
• High‑speed signaling (up to 50 Gbps, NRZ, PAM4)
• PCB stack‑up design and impedance control
