System Signal/Power Integrity Engineer

Job Title

System Signal/Power Integrity Engineer

Role Summary

Work on system-level signal and power integrity for high-data-rate SerDes applications (up to 400G). Lead measurement-simulation correlation, modeling, and lab-based debug across silicon, package, and PCB domains.

Collaborate with package, PCB and silicon teams to define SI/PI requirements, perform pre- and post-layout simulations, and deliver validated models and documentation to internal and customer teams.

Experience Level

Senior — the role requires substantial experience (see Education Requirements for degree + years guidance).

Responsibilities

Primary duties include analysis, modeling, measurement, and cross-team coordination to ensure signal and power integrity for high-speed systems.

• Support high-data-rate SerDes system design and debug (up to 400G).
• Perform system-level SI/PI design trade-offs, pre-layout and post-layout modeling, and simulation.
• Develop 3D/2.5D/2D EM models and run field-solver simulations (e.g., HFSS/SIWave); assess model accuracy and trade-offs.
• Run circuit and link-level simulations (e.g., Keysight ADS) and statistical/bit-by-bit SerDes simulations.
• Design and execute high-frequency measurements (VNA/TDR 50+ GHz), capture high-fidelity lab data, and correlate with simulations.
• Evaluate PCB/package materials, laminates, connectors, and PDN solutions for system performance.
• Document and deliver SI/PI models, reports, and requirements to internal teams and customers.
• Support customer analysis and debug efforts; communicate complex results clearly in reports and presentations.
• Manage multiple projects and track deliverables and timelines.

Requirements

Must-have technical skills and experience needed to perform the role; nice-to-have items are listed separately.

• Proven experience in signal integrity for high-speed digital applications, including transmission-line and electromagnetic-field theory.
• Experience with EM field solvers and model development (Ansys HFSS, SIWave, Q3D or equivalent).
• Experience with circuit and link simulation tools (Keysight ADS).
• Hands-on measurement experience with VNA, TDR (50+ GHz), sampling and real-time oscilloscopes, and spectrum analyzers; ability to capture and analyze lab data.
• Knowledge of SerDes metrics and analysis: insertion/return loss, crosstalk, BER, jitter, statistical eye diagrams, phase noise, and jitter sensitivity.
• Power integrity skills: PDN impedance analysis, ultra-low impedance measurements, SMT capacitor behavior, and PDN simulation tools (CPA/SI-Wave).
• Experience collaborating with package and PCB engineers and translating system requirements into package/PCB constraints and deliverables.
• Strong numerical analysis and measurement-simulation correlation skills; ability to determine appropriate model fidelity for design decisions.

Nice-to-have:

• Matlab, Cadence APD/Allegro, Polar, Q3D, Linux, Keysight AEL.
• Familiarity with photonics/optical channel impairments (CWDM, OMA, chromatic dispersion, four-wave mixing).

Education Requirements

BS with 12+ years, MS with 10+ years, or PhD with 7+ years of experience in Electrical Engineering or Physics.
