Role Overview

Astera Labs is seeking a Quality Engineer to join our Product Quality Engineering team in San Jose, CA. This is an exciting opportunity for an early-career engineer to dive into the heart of AI infrastructure connectivity, working hands-on with cutting-edge semiconductor devices that power the world's most advanced data centers.

In this role, you will be instrumental in driving root-cause analysis of failures across circuit, package, firmware, and protocol layers — directly impacting the reliability and quality of our PCIe and Ethernet connectivity solutions. You'll work with state-of-the-art lab instrumentation, build infrastructure to accelerate failure analysis, and collaborate across engineering disciplines to ensure Astera Labs continues to deliver best-in-class silicon to hyperscale customers. If you're passionate about high-speed SERDES, signal integrity, and solving complex hardware problems at the intersection of AI and connectivity, this is the role for you.

Key Responsibilities

•
Failure Analysis & Root-Cause Infrastructure

• Enable and develop infrastructure such as databases to optimize and reduce time to root-cause failures in circuit, package, firmware, or protocol-level iterations

• Participate in the new product development process to enable improvements and capabilities for failure analysis

• Document product quality engineering processes and methodologies to ensure repeatability and scalability

•
Lab Measurement & Debug

• Perform measurements on high-speed SERDES, PCIe, and Ethernet devices to characterize and debug quality issues

• Set up and use advanced lab instrumentation including BERT, high-bandwidth oscilloscopes, protocol analyzers, VNAs, TDR, and spectrum analyzers to support debug and root-cause activities

•
Cross-Functional Collaboration

• Collaborate with design, validation, hardware, and system engineering teams to resolve quality issues and drive continuous improvement

• Support cross-functional efforts to improve product reliability and manufacturing quality

Basic Qualifications

• Bachelor's degree in Electrical Engineering, Computer Engineering, or a related field

• Understanding of high-speed serial interfaces (PCIe, Ethernet, SERDES)

• Familiarity with lab instrumentation such as oscilloscopes, BERT, TDR, or spectrum analyzers

• Strong analytical and problem-solving skills

• Excellent documentation and communication skills
