Required and preferred rules are kept separate and reflect the wording in the original posting.

About the Role

You will validate Scale-Up Ethernet endpoints and switch fabrics from pre-silicon prototypes through silicon integration. You will diagnose performance bottlenecks and data-transfer failures across hardware, firmware, drivers, software, and fabrics. You will build, manage, observe, and test rack-scale systems; automate validation workflows; and evaluate AI workload performance and network interoperability.

Requirements

  • Bachelor's degree in computer science, electrical engineering, or a related field, or equivalent practical experience
  • Understanding of data-center Ethernet networks, switches, lossless networking, and RDMA
  • Experience configuring and debugging network devices or systems in Linux
  • Experience developing or debugging semiconductor system software at register and memory-map level
  • Experience with rack or cluster bring-up, integration validation, and performance analysis
  • Ability to automate testing, device control, and log collection using Python or Shell scripts
  • Experience using AI tools and coding agents and validating their outputs with evidence
  • Ability to develop hypotheses from packets, logs, and performance counters and narrow root causes through reproducible experiments
  • Ability to collaborate across engineering specialties and clearly document validation methods and results

Responsibilities

  • Validate Scale-Up Ethernet endpoint and SoC integration from pre-silicon prototypes through silicon
  • Configure and tune NICs and switch fabrics for workload traffic characteristics
  • Analyze packet captures, device counters, logs, and telemetry to isolate faults and bottlenecks
  • Build clusters for collective communication and LLM inference and training workload evaluation
  • Validate link stability and interoperability across MAC, PCS, FEC, SerDes, optical modules, and cables
  • Design and build rack and fabric management systems
  • Design rack-scale observability, failure detection, isolation, recovery, and reliability validation
  • Configure and validate Scale-Up Ethernet rack systems from link bring-up through rack integration
  • Automate remote console and power control, test execution, and result collection
  • Orchestrate AI agents for equipment bring-up, testing, log analysis, and documentation
  • Apply OCP, UEC, and SONiC Scale-Up standards and collaborate with vendors
