Experience Level
Desired Skills
Software Engineering
  • BS or MS degree in EE, ECE or CS
  • 5+ years of practical experience in silicon/system bring-up and debug
  • Demonstrated experience with high-speed Ethernet subsystem bring-up [minimum 56G PAM4, 100G/200G ports]
  • Understanding of embedded/system FW and PHY drivers for triage and diagnostic tooling
  • Excellent debugging skills at both SoC and system level
  • Strong programming and scripting skills (C/C++, Python, bash, etc.)
  • Self-starter and ability to drive tasks to completion with minimal guidance
  • Develop and execute post-silicon bring-up and validation plan (characterization, stress test, functional and performance validation) for Ethernet physical layer(L1) in the SambaNova DataScale® system
  • Provide leadership and domain expertise for Ethernet physical layer up to 100G PAM4, 400/800G ports , FEC, MAC/PCS
  • Perform system-level debug and root-cause analysis through bring-up, validation, and production phase
  • Partner with system, product, and software teams on product test deployment, RMA debug, and product release
  • Collaborate with design, verification/emulation and software to ensure bring-up readiness (e.g. power-on sequence, debug tool and script, contingency planning)
  • Engage in pre-silicon verification, emulation and software development effort related to Ethernet L1 layer
  • Drive technical innovation in post-silicon infrastructure including tools and script development, technical and procedural methodology enhancement, and ongoing monitoring and other cross-functional technical initiatives
Desired Qualifications
  • Familiarity with pre-silicon validation/emulation
  • Ability to isolate/triage electrical vs functional issues
  • Working knowledge of Ethernet architecture (MAC/PCS/FEC) and experience engaging with architects and vendors on these issues
