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 independently.

- Experience debugging issues across hardware, firmware, and software.

- Experience validating high-speed interfaces such as PCIe, Ethernet, SerDes, CXL, or DDR.

- Hands-on experience working in a hardware or system validation laboratory.

- Strong communication and cross-functional collaboration skills.

Preferred Qualifications:

- Experience with PVT validation, silicon corner testing, characterization, qualification, and margin analysis.

- Experience with server, storage, networking, or AI infrastructure products.

- Familiarity with PCIe/CXL architecture and high-speed SerDes technologies.

- Experience with oscilloscopes, BERTs, protocol analyzers, traffic generators, or similar lab equipment.

- Working knowledge of Python, firmware, Linux, and system-level software debugging.

- Experience developing automated validation and regression environments.

- Familiarity with Git and software development practices.

- Experience with pre-silicon validation, emulation, or hardware prototyping.

- Experience with system performance, throughput, latency, power, and stability testing.
