Your Role

Key responsibilities in your new role

• Architect and simulate DSP signal chains for automotive Ethernet PHYs: define features, performance targets, and algorithm specs for mixed-signal and digital teams
• RTL Design and Verification
• Develop equalization and adaptation algorithms for wireline channels(e.g., FFE/DFE, adaptive filtering), including fixed-point considerations
• Design and implement timing recovery/synchronization blocks (CDR, tracking loops), including jitter tolerance and stability/latency tradeoffs
• Contribute to detection and coding / FEC integration: soft-information interfaces, performance/complexity tradeoffs, and linkKPIs
• Build bit-true / fixed-point models and reference implementations primarily in C++ and MATLAB (Python optional, not core
• Define verification metrics and stress tests (BER/FER, convergence time, corner case s) and partner with DV to ensure coverage
• Support silicon bring-up and lab debug: correlate model ↔ silicon, root-cause issues, and iterate on algorithms/specs
• Collaborate across architecture, design, verification, and applications to deliver implementable and testable solutions

Your Profile

Qualifications and skills to help you succeed

• B.S. + 10 years (or M.S. + 7 years) in Electrical Engineering, Computer Engineering, or related field
• Strong fundamentals in digital communications and DSP, including probability/statistics
• Practical experience in high-speed wireline DSP, including some mix of: FFE/DFE, adaptation, CDR, MLSD/Viterbi concepts, FEC integration, fixed-point modeling
• Strong C++ and MATLAB skills for algorithm development, modeling, and analysis

• Experience with automotive Ethernet PHY/SerDes constraints(robustness, low latency, interoperability, EMI resilience)
• Familiarity withADC-based receiver architectures and calibration concepts
• Experience translating algorithms into RTL-friendly specs (throughput/latency budgeting, memory/compute sizing, state-machine behavior)
• Knowledge of link startup/training / autoneg concepts and system validation
• Exposure to standards work (e.g., IEEE 802.3) or cross-company technical leadership
