Role Overview

As the HSIO Architect, you will own the high-speed interface architecture across the various product families. You will drive decisions from SerDes architecture to UCIe die-to-die integration, working directly with the Head of Engineering, digital leads, and analog teams. You will also serve as the technical interface to key IP vendors (UCIe PHY, SerDes), foundry partners and anchor customers.

This is not an IP integration role. We need someone who can define the architecture, validate the tradeoffs, and guide execution through tape-out.

What You’ll Do

Architecture & Definition

Define high-speed IO architecture for PCIe/Ethernet-224G/448G scale-up fabric/CPO-optics to electrical interfaces
Define die-to-die interface architecture for UCIe integration: flit formats, credit-based flow control, sideband management, and latency targets
Architect the SerDes-to-photonics interface, retimer integration, and co-packaged optics (CPO) readiness
Own the signal integrity budget: TX/RX equalization, channel loss allocation, crosstalk margins,



and jitter decomposition across the full channel
Implementation Oversight
Guide SerDes PHY selection and evaluation; assess vendor IP (custom vs. licensed), and establish integration requirements
Define and review UCIe PHY integration: bump map, power domain partitioning, analog/digital co-design requirements, and pad ring architecture
Collaborate with digital architecture lead on protocol bridge design — PCIe TLP ↔ UCIe flit conversion, flow control, error handling
Drive DFT and compliance test architecture for PCIe certification and UCIe conformance testing
Establish PVT margin strategies and power management per-lane DVFS, shutdown sequences, and IVR chiplet coordination

Customer & Ecosystem Engagement

Serve as primary technical interface to anchor customers and engaging hyperscaler architecture teams (AWS, Google, Microsoft, Meta) to validate product definition against platform requirements
