Principal TPIP/HSIO Engineer

Job Title

Principal TPIP/HSIO Engineer

Role Summary

Lead pre-silicon quality and silicon-to-simulation correlation for high-speed I/O subsystems (DDR, PCIe, eUSB, SerDes) across SoC projects. Partner with IP vendors, integration, architecture, validation, DFT and test teams to meet DFX targets from simulation through silicon.

Positions based in San Jose, Austin, Seattle, or San Diego on a hybrid working model. Salary range: $262,700–$355,400 per year.

Experience Level

Senior - typically requires 10+ years of relevant experience.

Responsibilities

Primary duties focus on pre-silicon quality, silicon correlation, and cross-team leadership.

• Collaborate with IP vendors and internal integration/architecture/DV/DFT/PTE teams to ensure silicon quality for HSIO blocks (DDR, PCIe, eUSB, D2D).
• Drive closure on DFX metrics: test coverage, margin analysis, stuck-at/scan coverage, and clock-domain checks.
• Develop and maintain methodologies to validate that silicon behavior matches pre-silicon estimates.
• Analyze silicon measurements (eye diagrams, BER, BIST logs) and correlate results to design and simulation data.
• Chair DDR and PCIe TPIP Councils to harmonize quality criteria, test architectures, and vendor deliverables across projects.
• Partner with Architecture, Integration, Validation, Package, and SIPI teams to anticipate and resolve integration challenges.

Requirements

Must-have skills and experience for this role.

• 10+ years experience in high-speed interface design, validation, or bring-up (DDR, PCIe, SerDes).
• Proven post-silicon characterization experience (BER, margining) and correlating results with pre-silicon simulations.
• Strong scripting skills for data parsing, test automation, and visualization (Python, TCL).
• Experience analyzing silicon measurement data (eye diagrams, BER, BIST logs) and deriving actionable conclusions.
• Excellent written and verbal communication; able to drive technical discussions across vendors and internal teams.
• No relocation package is available for this role.

Education Requirements

Bachelor's or Master's degree in Electrical Engineering or a related technical field.
