Job Title

Senior PHY System Engineer

Role Summary

Join the End-to-End (E2E) physical-layer performance team in Post-silicon to lead link-level performance characterization, verification, and debugging for NVIDIA electro-optical and electrical products. The role focuses on silicon bring-up, lab measurements, and driving products to mass production with first-class performance.

Experience Level

Senior — 5+ years of experience in high-speed system engineering roles.

Responsibilities

Primary responsibilities include hands-on testing, debugging, and driving cross-team validation of PHY-level performance.

• Own link-level performance characterization, verification, and debugging.
• Debug system-level link issues across hardware and firmware/software.
• Characterize electrical and optical performance using lab instruments (oscilloscopes, VNAs, spectrum/network analyzers, pattern generators).
• Lead silicon bring-up activities and manage end-to-end testing of new ASICs toward production readiness.
• Define test requirements from electrical and optical specifications.
• Set up and validate complex lab testbeds for electro-optical and high-speed electrical measurements.
• Collaborate with test teams to monitor test flows and resolve issues.
• Lead data-driven reviews on product functionality and improvement areas.

Requirements

Must-have technical skills and experience required to perform the role; followed by desirable qualifications.

• 5+ years of proven experience in high-speed system engineering.
• Strong debugging, problem-solving, and analysis skills; demonstrable examples required.
• Basic software/firmware debugging abilities.
• Basic understanding of PCB layout and high-speed board design issues.
• Strong collaboration and interpersonal skills; ability to guide and influence cross-functional teams.

Nice-to-have:

• Experience with customer technical support and industry specifications (IEEE, OIF).
• Hands-on lab experience with high-speed electro-optical designs and associated equipment.
• Familiarity with optical assembly components (high-speed cables, lasers, diodes).
• Basic scripting skills (Python, MATLAB) for data analysis and automation.
• Experience establishing complex lab setups using optical and electrical high-speed instruments.

Education Requirements

B.Sc. degree in Electronic Engineering required.
