PHY Algorithm Engineer at Cisco

Cisco Silicon One Israel is seeking PHY Algorithm Engineer, Cisco Silicon One Israel

Meet the Team

You will join the Ser Des System Algorithm team within Cisco Silicon One in Israel, part of Cisco's silicon development organization. The team works across modem technology, system modeling, and signal processing for high-speed Ser Des devices.

Cisco Silicon One is at the center of Cisco's ASIC group, building next-generation network devices for AI networks, the 5G era, and the future of routing. Our design center brings silicon hardware and software disciplines together in one site, combining a small-team startup atmosphere with the scale and stability of Cisco.

Your Impact

As a PHY Algorithm Engineer, you will develop, model, configure, and optimize algorithms for advanced Ser Des modem systems. You will work with the latest silicon technologies and processes to help build large-scale, complex devices at the edge of feasibility.

Your work will contribute to Cisco Silicon One, a unified and programmable silicon architecture designed for service provider and web-scale markets. The role requires technical depth in digital signal processing, modem behavior, using MATLAB for algorithm development from the idea to advanced Ser Des systems.

• Research, design and develop PHY and modem algorithms for high-speed Ser Des devices.
• Build and use system models to analyze modem behavior, signal-processing performance, and algorithm tradeoffs.
• Configure, tune, and optimize modem behavior to improve performance, robustness, and implementation feasibility.
• Use MATLAB for algorithm development, simulation, testing, and data analysis.
• Collaborate with silicon hardware and software teams to move algorithms from modeling into practical implementation.
• Support lab-based validation and debug activities when required.

Minimum Qualifications:

• Bachelor's degree or higher in Electrical Engineering or a related field.
• 3+ years of experience in electrical engineering, algorithm development, modem systems, or related high-speed communication systems.
• Experience with modem technologies, modem behavior, and relevant communication protocols.
• Strong background in digital signal processing, including digital signal analysis and algorithm development.
• Hands-on MATLAB experience for algorithm development, simulation, and testing.

Preferred Qualifications:

• Experience with modem configuration, optimization, and performance tuning.
• Experience with Ser Des systems, PHY development, or high-speed silicon devices.
• Experience with lab work, validation, measurement, or debug of communication systems.
• High attention to detail and a disciplined approach to accuracy and precision in algorithm development.
• Adaptability in evolving project requirements and strong collaboration in a small-team engineering environment.
