## Description

The Product Operations team within the Core Routing Business Unit (CRBU) plays a critical role in delivering Cisco’s next-generation hardware products at scale. Working at the intersection of engineering, supply chain, and manufacturing, the team ensures seamless product lifecycle execution,from new product introduction to high-volume production and customer delivery.

As a Hardware Engineer, you will work across a broad spectrum of the Cisco portfolio,including system and board design, signal integrity, power design, and validation. You will collaborate with multi-functional teams and external partners to optimize performance, cost, and quality.

Responsibilities:

- Silicon, Package & Board Characterisation: Validate high-speed channels from silicon die through the PCB interface using advanced time-domain and frequency-domain techniques. Partner with layout engineers to optimise routing and define manufacturing test requirements.

- PCIe Gen 6 Validation: Execute physical layer compliance and characterisation for PCIe Gen 6/7 protocols, utilising PAM4 signalling, multi-tap equalisation, and advanced clocking architectures.

- High-Speed Measurement Execution: Operate precision lab instrumentation, including multi-port Vector Network Analysers (110GHz+), high-bandwidth Oscilloscopes, Bit Error Rate Testers (BERTs), and Time Domain Reflectometers (TDRs).

- Measurement-to-Simulation Correlation: Extract S-parameters and utilise tools such as Ansys HFSS, Keysight ADS, or Cadence Sigrity to correlate lab data with simulation models. Drive root-cause analysis based on these findings.

- Root-Cause Debugging: Troubleshoot complex signal and power integrity anomalies, such as insertion/return loss, crosstalk, jitter, and noise, to ensure robust product performance.

- Lab Automation: Develop and maintain Python or MATLAB scripts to automate instrument control, streamline data collection, and process complex validation datasets.

Minimum Qualifications:

- Bachelor's degree and 5+ years of related experience, or Master’s degree and 3+ years of related experience, or PhD plus 1+ years of related experience.

- 5+ years of applied experience with VNA to measure multiport S Parameter (insertion loss, return loss and X talk)

- Capability to set up TDR setups to locate impedance discontinuity, trace routing mismatches, structural damage in PCB, cables and connectors

Preferred Qualifications:

- Prior experience with micro probing station, high bandwidth differential probes, calibration methodology.

- Basic scripting skills in Python or MATLAB to parse data and analyse data.

The starting salary range posted for this position is $138,100.00 to $196,500.00 and reflects the projected salary range for new hires in this position in U.S. and/or Canada locations, not including incentive compensation*, equity, or benefits.
