PHY Algo ASIC Engineer

Описание

As a PHY Algorithm Engineer, you will contribute directly to the modeling, simulation, and performance optimization of advanced physical layer (PHY) and modem algorithms for Cisco's flagship Silicon One ASICs.

Responsibilities

• Model & Develop PHY Algorithms: Design, simulate, and analyze digital signal processing (DSP) and modem algorithms for high-speed SerDes physical layer architectures
• Build High-Fidelity Simulation Models: Develop and maintain comprehensive MATLAB and Simulink models to evaluate bit error rates (BER), equalization tradeoffs (CTLE, FFE, DFE), and noise performance
• Optimize Modem Parameters: Characterize and tune algorithm configuration parameters to enhance receiver sensitivity, link robustness, and hardware implementation feasibility
• Support Hardware & Software Integration: Collaborate closely with digital ASIC design, firmware, and systems engineering teams to ensure accurate fixed-point translation and RTL implementation of algorithm models
• Perform Lab Validation & Debug: Participate in hands-on silicon bring-up, lab measurements, and data collection to correlate simulation predictions with real-world silicon behavior

Requirements

• Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or a related technical discipline
• 2+ years of hands-on experience in PHY algorithm development or related high-speed communication systems, with a broad system-level orientation and perspective
• Hands-on MATLAB experience for algorithm development, simulation, and testing
• Solid theoretical foundation in digital signal processing (e.g., adaptive filtering, equalization, clock and data recovery, modulation)
• Practical understanding of communication systems and receiver/transmitter modem architectures

Nice to have

• Experience with high-speed SerDes systems, wireline communications, or high-speed optical/electrical PHY architectures
• Hands-on experience with lab test equipment (high-bandwidth oscilloscopes, BERTs, spectrum analyzers) for silicon characterization and signal integrity validation
• Familiarity with fixed-point modeling, C/C++, or Python scripting for simulation flow automation
• Background in algorithm tuning, parameter optimization, or link-budget analysis
• Strong analytical mindset, proactive problem-solving skills, and a collaborative team orientation

We offer

• Opportunities to grow and build are limitless
• Work as a team, collaborating with empathy
• Benefits designed to support every aspect of your life: from your well-being to your time away to your family
