Full Job Description
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 cases) and partner with DV to ensure coverage
  • Support silicon bring-up and lab debug: correlate model 14 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
Preferred qualifications
  • Experience with automotive Ethernet PHY/SerDes constraints(robustness, low latency, interoperability, EMI resilience)
  • Familiarity with ADC-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
