Principal Engineer DSP PHY Digital Design

Job description

Build the future nobody's dreamed of yet... are you ready to rethink the impossible?

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 ↔ silicon, root-cause issues, and iterate on algorithms/specs
• Collaborate across architecture, design, verification, and applications to deliver implementable and testable solutions 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 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 We are on a journey to create the best Infineon for everyone.

This means we embrace diversity and inclusion and welcome everyone for who they are. At Infineon, we offer a working environment characterized by trust, openness, respect and tolerance and are committed to give all applicants and employees equal opportunities. We base our recruiting decisions on the applicant´s experience and skills.
