Role Summary
We are seeking a Sr. Principal Digital Designer to lead the architecture, implementation, and integration of digital subsystems for Automotive Ethernet PHY products (10BASE‑T1S, 100BASE‑T1, 1000BASE‑T1, and multi‑gig automotive SerDes technologies).
The role involves driving digital micro-architecture, state machines, PCS functionality, safety mechanisms, and end‑to‑end digital design across the PHY.
Key Responsibilities
1. Architecture & Technical Leadership
Define and own digital subsystem micro‑architecture for Automotive Ethernet PHYs, including:
PCS pipelines and encoding/decoding logic
Scramblers/descramblers, CRC engines, alignment & framing
Packet processing, link monitoring, error handling
Interface logic (MII, RMII, RGMII, GMII, XGMII depending on product line)
Processor based SoC design
Perform system‑level partitioning between digital, analog/mixed-signal, and firmware components.
Lead feasibility studies, power/performance trade-offs, and digital architecture exploration.
2. RTL Design & Implementation
Develop high-quality RTL (Verilog/SystemVerilog)



for control, datapath, and protocol logic.
Drive digital front-end flows including:
Lint, CDC/RDC, reset architecture, synthesis guidance
Timing constraints and logic optimization
Work with DV to define coverage goals, corner cases, and feature verification plans.
3. System‑Level Ownership
Translate system requirements, IEEE 802.3 specifications, and architecture documents into robust digital designs.
Work with mixed-signal teams to define:
Control interfaces to analog front‑end blocks
Calibration engines, register programming flows, and digital‑analog interaction models
Contribute to bring‑up sequences, compliance testing, and system validation.
4. Automotive Quality & Functional Safety
Ensure compliance with Automotive Ethernet standards, ISO 26262, and AEC‑Q100 expectations.
Define and implement:
Safety mechanisms (BIST, LBIST/MBIST, error detection schemes)
Diagnostic monitors, timeout reco
