Distinguished Diagnostics Quality Engineer
role at
Astera Labs . Role Overview As a Distinguished Diagnostics Quality Engineer, you will be responsible for ensuring the quality and reliability of Astera Labs’ advanced semiconductor products across their lifecycle — from design through high-volume manufacturing. You will lead the development and implementation of diagnostic test strategies, define diagnostic coverage metrics, and enable robust debug methodologies across leading-edge process technologies (16nm to
Responsibilities Diagnostic Test Development: Define and deploy diagnostic test plans, fixtures, tools, and methodologies for fault isolation of customer returns in PCIe, CXL, UCIe, Ethernet and other high-speed switching products. Scale successful tools for broader use in high-volume manufacturing and troubleshoot NPI qualification failures or field issues. Embedded Silicon Agent Champion: Drive selection or development of embedded silicon agents to monitor temperature, voltage, noise, process, timing, etc., at the block level on chip. Collaborate with design, validation, and firmware teams to debug features in the lab and enable real-time adaptive behavior. Partner with software teams to process data and produce actionable diagnostic conclusions. Design DFT Review: Collaborate with design, operations engineering, and system validation teams to drive early Design-for-Testability (DFT) and diagnostic capabilities, ensuring coverage and applying lessons learned. Advanced Packaging Diagnostics: Develop diagnostic methodologies for MCM, 3DIC, and optical interconnect packages, including die-to-die and heterogeneous integration interfaces. Issue Debugging: Lead debugging of complex hardware, firmware, and software issues during NPI and high-volume production using diagnostic hooks and advanced tools. Advanced Quality Data Analytics: Build data systems to eliminate outliers, predict quality trends, and identify improvement opportunities; develop signature analysis techniques using AI/ML where appropriate. Diagnostic Pattern Improvement: Improve diagnostic efficiency, reduce retest, and boost product yield and quality. Automation & Scalability: Develop and maintain automated diagnostic tools to scale and reuse across product families. Lifecycle Quality: Integrate diagnostics into silicon lifecycle management, firmware release, and reliability tracking to detect degradation or field risks. Interoperability & System Level Support: Ensure interoperability, diagnostic transparency, and robust field debug capability across teams. Skills And Experience Deep experience with digital and Serdes high-speed protocols (PCIe Gen5/Gen6, CXL, UCIe, Ethernet/SerDes) and system-level validation methodologies. Experience with embedded silicon diagnostic agents and product characterization & test planning. Hands-on lab debug tools proficiency (protocol analyzers, oscilloscopes, BERTs, error-injection frameworks). Scripting and software development (Python, C/C++, Java or similar) for diagnostic automation and data analysis. Ability to analyze complex test data, identify root causes, and implement systemic solutions. Familiarity with semiconductor test flows (ATE, system-level test, characterization, production validation). Experience with advanced packaging technologies (MCM, 3DIC, optical) and their diagnostic/test challenges. Strong communication skills to collaborate across design, product, test, and customer teams. Demonstrated ability to influence cross-functional decisions and drive quality improvements. Preferred Qualifications Minimum of 5 years leading a high-caliber product engineering team. Minimum of 10 years within a product or diagnostics engineering team with successful deployment of semiconductor devices into production. Bachelor’s degree in Electrical Engineering required; Master’s preferred. Experience with diagnostic firmware and test development. Knowledge of anomaly detection techniques in diagnostic/test data. Track record of leadership in new product introduction (NPI) for complex, high-speed semiconductor products. We know that creativity and innovation happen more often when teams include diverse ideas, backgrounds, and experiences, and we actively encourage everyone with relevant experience to apply, including people of color, LGBTQ+ and non-binary people, veterans, parents, and individuals with disabilities.
