DDR Memory Interface System Validation Lead Engineer

Job Title

DDR Memory Interface System Validation Lead Engineer

Role Summary

Lead validation engineer responsible for DDR5 and LPDDR5 memory subsystem validation across FPGA programs within the Silicon and Platform Validation organization. Work with architecture, silicon design, board design, firmware, signal integrity, and software teams to ensure quality, reliability, performance, and interoperability of memory subsystems and high-speed I/O.

Hands-on role executing pre- and post-silicon validation, developing test suites and automation, and improving validation methodologies and infrastructure.

Experience Level

Senior — minimum of 8+ years of industry experience in memory subsystem validation, silicon validation, or high-speed interface validation.

Responsibilities

Primary responsibilities include:

• Define and own DDR5 and LPDDR5 memory subsystem validation strategies and execution across multiple FPGA programs.
• Create system-level validation environments and comprehensive test suites for advanced memory interfaces.
• Perform pre-silicon and post-silicon functional and electrical validation of memory controllers, PHYs, and associated high-speed interfaces.
• Develop and execute validation plans for initialization/training, read/write functionality, margining, stress testing, frequency scaling, stability, reliability, and error recovery.
• Perform timing characterization, compliance checks, interoperability testing, and performance validation per JEDEC specifications.
• Analyze signal integrity and timing behavior (eye diagrams, jitter, timing margins) and debug complex silicon, firmware, board-level, and system-level issues.
• Collaborate with board design teams on stack-up, routing, SI/PI, topology optimization, termination, and power delivery; review schematics and layouts.
• Use protocol analyzers, oscilloscopes, logic analyzers, and traffic generators for debug and characterization.
• Develop, standardize, and maintain validation methodologies, automation frameworks, and measurement flows to improve scalability and efficiency.
• Lead root-cause analysis and drive issue resolution across silicon, package, board, firmware, and software teams.

Requirements

Must-have skills and experience:

• Extensive hands-on experience validating DDR5 and LPDDR5 memory subsystems, controllers, and PHYs.
• Strong background in pre-silicon and post-silicon validation for high-speed interfaces and memory controllers.
• Proven ability to perform timing characterization and signal integrity analysis for high-speed memory channels.
• Experience with JEDEC compliance, interoperability testing, and performance validation.
• Skilled in debug using oscilloscopes, protocol analyzers, logic analyzers, and traffic generators.
• Experience developing test automation, validation frameworks, and measurement flows.
• Ability to collaborate cross-functionally with silicon, board, firmware, and software teams to drive resolution.
• Excellent problem-solving and technical communication skills.

Nice-to-have:

• Experience with FPGA platform validation and PHY architectures.
• Scripting and automation skills (e.g., Python, TCL) and familiarity with test infrastructure development.
• Prior experience leading validation teams or mentoring engineers.

Education Requirements

Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Electronics Engineering, or a related technical field (as listed in the posting).
