Signal and Power Integrity Engineer

At Cisco, Bangalore, the Network Hardware Engineering (NHE) architects, designs, builds, and delivers world-class Access, Edge, Aggregation, and Core routers that cater to the growing bandwidth demands of leading service providers and large enterprises.

As Signal and Power Integrity Engineer in this team of outstanding engineers from a diverse group of backgrounds, you will be responsible for delivering system-level signal and power integrity solutions for large sophisticated high-speed systems, boards & packages.

Key responsibilities:

• Develop SI rules, review design implementation, build test plans, and document characterisation & measurement reports.
• Improve & optimise design margins through interconnect, timing and crosstalk analysis, 3D EM & channel simulations for high-speed designs.
• Design & characterise test structures & channel models to correlate simulations with measurements for Serdes and interconnects.
• Collaborate with multi-functional teams - HW, PCB Layout, SW, MFG, ASIC.
• Be responsible for electrical characterisation and verification of Transmitter/Receiver SERDES settings to meet the industry standards and internal Cisco requirements.

Minimum qualifications and expectations:

• Bachelor's or Master’s Degree in Electrical Engineering,
• 7+ yrs of demonstrated ability in hardware design with emphasis on Signal and Power Integrity
• Hands on exposure to lab measurements including real-time scope, sampling scope, Spectrum analyser, VNA & TDR.
• Good understanding of EM and transmission line concepts, timing, jitter, crosstalk, noise, channel modelling, channel equalisation techniques, power delivery & decoupling.
• Experience with 56G PAM4, 25G & 10G NRZ Serdes technologies, and DDR - simulation, bring up, debug, measurements, and optimisation.
• Thorough knowledge of PCB stack-up design - standard processes, performance vis-à-vis PCB materials, surface finishes, vendor capabilities, and manufacturing trade-offs.
• Proficiency with simulation and analysis tools like ADS, HFSS, HSPICE, Cadence Allegro, PowerSI, MATLAB, and Hyperlynx.
• Excellent oral and written communication skills and capability to present concepts, analysis, and updates to larger teams and forums.
