Overview: Astera Labs is seeking a motivated Senior System Validation Engineer to join our growing post-silicon validation team in Israel and support next-generation connectivity products for AI and data-center applications. In this role, you will perform system-level post-silicon validation, characterization, and debug across silicon, hardware, firmware, and software. You will support silicon bring-up and PVT/corner testing, develop and execute functional and system validation tests, analyze results, and work with cross-functional teams to identify and resolve complex system issues. This is a highly hands-on lab position. The primary location is Haifa , with temporary support at the Ramat Gan lab as needed. Key Responsibilities: • Develop and execute post-silicon functional and system validation from silicon bring-up through production readiness. • Run PVT, silicon corner, stress, characterization, and qualification testing across a wide range of operating conditions. • Develop validation tests to verify functionality, performance, stability, power, and operating margins. • Debug issues across silicon, hardware, firmware, drivers, and system software. • Validate high-speed interfaces such as PCIe, CXL, Ethernet/SerDes, and DDR, as well as common system interfaces. • Develop Python scripts and automation to improve validation coverage, regression, and test efficiency. • Analyze validation data, identify issues and trends, and drive problems to root cause and closure. • Work closely with hardware, architecture, firmware, software, design, and DV teams to investigate and resolve issues. • Support the transition of new silicon from initial bring-up to a qualified, production-ready product. • Operate system platforms and laboratory equipment to support validation and debug. • Document test results, issues, root cause, and recommendations and communicate findings clearly. Basic Qualifications: • B.Sc. or M.Sc. in Electrical Engineering, Computer Engineering, Computer Science, or a related field. • 6+ years of experience in post-silicon, system, hardware, or product validation. • Hands-on experience with SoC/silicon bring-up, functional validation, and system-level debug. • Experience developing and executing validation plans, test cases, and characterization experiments. • Strong Python scripting and test automation skills. • Strong hardware debugging, analytical, and problem-solving skills with the ability to work independent
