About the Role

We are looking for a hands-on ETH SerDes Validation Engineer to lead and execute 112G and next-generation 224G SerDes validation activities.

The role involves deep lab work with Keysight test equipment, automation development, and direct execution of compliance and characterization tests according to industry standards.

This position is ideal for an engineer who combines strong signal-integrity fundamentals, standards expertise, and automation-driven validation in high-speed silicon and system environments.

Key Responsibilities

• Perform end-to-end validation of 112G / 224G SerDes PHYs at silicon, package, and system levels

• Execute compliance, characterization, and stress tests for high-speed serial links

• Operate and configure Keysight high-speed test equipment, including:

• BERTs, oscilloscopes, AWGs, jitter sources, channel emulators (variable ISI)

• Develop and maintain automation frameworks for SerDes validation:

• Test setup control

• Data collection

• Result analysis and reporting

• Python

• Shell scripts under Ubuntu

• SQL skills for data analysis

• Execute and analyze:

• Eye diagrams, jitter (RJ/DJ/TJ), BER, bathtub curves

• CTLE/DFE behavior

• TX FIR optimization

• Channel loss and margin analysis

• Debug signal-integrity issues across:

• Silicon

• Package

• PCB

• Connectors and cables

• Work according to industry standards, including:

• IEEE (112G / 224G PAM4)

• Ethernet (802.3ck / 802.3db and beyond)

• Collaborate closely with:

• Design teams (SerDes / PHY)

• SI/PI engineers

• System and board design teams

• Document test methodologies, results, and recommendations clearly

Required Qualifications

• B.Sc. or M.Sc. in Electrical Engineering or equivalent

• 5+ years of experience in high-speed SerDes validation or signal-integrity roles

• Hands-on experience with 112G PAM4 SerDes validation

• Strong working knowledge of Keysight validation platforms (BERTs, scopes, automation APIs)

• Proven ability to write automation scripts

• Python

• Shell scripts

• SQL for Data Analysis

• Deep understanding of:

• PAM4 signaling

• Jitter decomposition

• BER and margining techniques

• Channel loss and equalization

• Solid understanding of high-speed standards (Ethernet, IEEE, OIF)

• Comfortable working independently in the lab and driving issues to closure

Preferred Qualifications

• Experience with 224G SerDes validation or early silicon bring-up

• Familiarity with Keysight N5991 / 8040 / 8160 / PNA / M8040A platforms

• Experience validating:

• 112G / 224G Ethernet

• Experience with compliance test specifications and interoperability testing

What We Offer

• Work on cutting-edge 112G / 224G SerDes technologies

• Direct impact on next-generation silicon and systems

• Advanced lab environment with state-of-the-art Keysight equipment

• Highly technical, expert-level team

• Competitive compensation and benefits

• Location in Kiryat Gat with access to major semiconductor programs
