Senior Staff Post-Silicon Automation Engineer (PAM4 DSP)

Job Title

Senior Staff Post-Silicon Automation Engineer (PAM4 DSP)

Role Summary

Join Marvell's Ethernet PAM4 Validation team to design and implement post-silicon validation and automation for high-speed Ethernet DSP/PHY products. The role focuses on automation, data-driven debug, and device- and switch-level validation to ensure product performance, interoperability, and customer readiness.

Experience Level

Senior-level. Experience guidance: Bachelor's + 3–15 years, or Master's/PhD + 2–10 years (see Education Requirements for details).

Responsibilities

Primary responsibilities include developing automation and validation workflows, executing post-silicon tests, and driving debug and closure of hardware/firmware issues.

• Develop Python, Shell, and automation scripts for test execution, data collection, log parsing, regression coverage, and dashboard reporting.
• Build AI-assisted validation workflows for automated test execution, failure triage, log analysis, anomaly detection, and artifact collection.
• Create intelligent debug agents that analyze telemetry, FEC counters, firmware logs, and register dumps to accelerate root-cause analysis.
• Collaborate with firmware, design, systems, software, and customer engineering teams to define coverage, reproduce failures, verify fixes, and close issues.
• Support customer programs and delivery milestones by improving validation coverage, execution efficiency, and automation quality.
• Develop and execute validation plans for Ethernet PAM4 DSP/PHY, ASICs, cables, optics, and switch-facing products.
• Perform device-level and switch-level post-silicon validation: bring-up, interoperability, performance characterization, stress testing, and link stability validation.
• Debug link-up, link-flap, signal integrity, firmware upgrade, interoperability, and customer-reported issues using lab equipment and logs.

Requirements

Must-have technical skills, working practices, and behavioral expectations.

• Hands-on lab experience with oscilloscopes, BERTs, protocol analyzers, optical switches, traffic generators, temperature chambers, or similar validation equipment.
• Strong automation skills using Python, Shell, or similar scripting languages for test execution, data collection, log parsing, and result analysis.
• Familiarity with Linux environments, device drivers, hardware/software interaction, lab servers, CI systems, and validation infrastructure.
• Strong debugging skills for link-up issues, signal integrity problems, firmware failures, interoperability issues, and customer defects.
• Ability to analyze large volumes of validation data, logs, counters, telemetry, and test results to identify root cause and drive closure.
• Clear communication skills and ability to collaborate with cross-functional teams.
• Ability to work independently in a fast-paced, ambiguous hardware development environment with aggressive timelines.

Education Requirements

Bachelor's degree in Computer Science, Electrical Engineering, Electronics Engineering, or a related field with 3–15 years of professional experience; or Master's/PhD in a related field with 2–10 years of experience. The posting also allows equivalent practical experience in related technical fields.

Nice to Have

Preferred skills and domain experience.

• Experience in validation, bring-up, debug, or characterization of DSPs, PHYs, SoCs, ASICs, or high-speed networking devices.
• Hands-on experience with Ethernet validation, PAM4 signaling, switch-level interoperability, device-level validation, or high-speed SerDes bring-up.
• Knowledge of high-speed interfaces such as Ethernet, PCIe, I2C, MDIO, CMIS, or related control interfaces.
• Experience working with switches, optics, AEC/ACC cables, PHY/DSP devices, firmware builds, and system-level validation environments.
• Experience with C/C++ or low-level software development for hardware control, register access, firmware interaction, or test development.
