About the Role

We are looking for a highly motivated Senior SerDes & High-Speed PHY Validation Engineer to play a key role in validating next-generation high-speed connectivity solutions for cloud, AI, and data center networking systems.

In this role, you will lead the validation and characterization of advanced Ethernet SerDes technologies spanning 112G PAM4 and next-generation 224G PHY architectures. You will work at the intersection of silicon design, signal integrity, system engineering, and validation, driving complex technical investigations from first silicon bring-up through compliance and product readiness.

This opportunity is ideal for engineers who enjoy combining deep signal integrity knowledge, hands-on lab ownership, automation development, and cross-functional technical leadership to solve challenging high-speed design and validation problems.

What You'll Do

Lead SerDes Validation and Characterization
- Drive end-to-end validation of high-speed Ethernet SerDes and PHY solutions across silicon, package, board, and system environments.




- Define and execute validation strategies for 112G PAM4 and next-generation 224G technologies.
- Develop characterization methodologies to assess performance, robustness, and design margins across operating conditions.
- Support silicon bring-up activities and root-cause analysis of complex system-level issues.

Execute Advanced High-Speed Measurements

Perform and analyze:
- Eye-diagram measurements
- BER and margin analysis
- Bathtub curve characterization
- Jitter decomposition (RJ, DJ, TJ)
- CTLE and DFE performance evaluation
- TX FIR optimization
- Channel loss and equalization analysis

Debug Complex Signal Integrity Challenges

Investigate and resolve performance limitations across:
- Silicon
- Package
- PCB channels
- Connectors
- Cables
- End-to-end system interconnects

Work closely with design and architecture teams to translate lab findings into actionable design improvements.
