Signal and Power Integrity Engineer - 4 to 7 Years - Bangalore

Cisco Systems, Inc; Bengaluru; On-site; INR 1,500,000 - 2,000,000; Full time

Job summary

Cisco Systems, Inc. in Bengaluru is seeking a Signal and Power Integrity Engineer to deliver system-level SI solutions for high-speed boards and packages. You will develop rules, plan tests, and document measurements to improve margins and ensure SERDES performance.

The role requires hands-on lab measurements, EM concepts, and experience with 56G PAM4/25G/10G NRZ Serdes, DDR, and PCB stack-up design. Collaboration with HW, PCB layout, SW, MFG, and ASIC is essential.

Qualifications

• Bachelor's or Master's Degree in Electrical Engineering.
• 4+ 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 analyzer, VNA & TDR.
• Good understanding of EM and transmission line concepts, timing, jitter, crosstalk, noise, channel modeling, channel equalization techniques, power delivery & decoupling.
• Experience with 56G PAM4, 25G & 10G NRZ Serdes technologies, and DDR - simulation, bring up, debug, measurements, and optimization.
• 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.

Responsibilities

• Be responsible for delivering system-level signal and power integrity solutions for large sophisticated high-speed systems, boards & packages.
• Develop SI rules, review design implementation, build test plans, and document characterization & measurement reports.
• Improve & optimize design margins through interconnect, timing and crosstalk analysis, 3D EM & channel simulations for high-speed designs.
• Design & characterize 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 characterization and verification of Transmitter/Receiver SERDES settings to meet industry standards and internal Cisco requirements.
