Overview

Astera Labs Inc. is seeking an experienced and self-driven Hardware Lab Engineer to join our dynamic team in developing world class connectivity products for AI infrastructure.

Job Description

This role will work closely with firmware, system validation, quality, and product engineers to support silicon bring-up, characterization, and debug activities through hands-on lab execution. The ideal candidate will have a deep understanding of circuits, hands-on experience with PCBAs and silicon test environments, and the ability to work on complex, open-ended tasks with minimal oversight.

Key Responsibilities

• Setup and maintain test environments for silicon validation and characterization. Configure and update hardware, software, firmware, and applications. Replicate BKCs.

• Conduct hands-on testing of silicon devices including PCIe Gen5/6/7, CXL, Ethernet, and other high-speed interfaces

• Install and configure servers, including FW, BIOS, OS, and network

• RMA intake/triage: inspection, electrical verification, screening (including CSAM inspection), and prioritization

• Manage logistics and communications with external labs

• Organize, track, and distribute lab equipment, hardware, and peripherals

• Ad hoc PCBA rework and soldering of fine-pitch SMD components

• Develop, document, and maintain lab procedures

Required Qualifications

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

• 5-12+ years of hands-on experience in lab environments supporting silicon validation or hardware development

• Proficiency with high-speed test equipment (oscilloscopes, protocol analyzers, BERTs, multimeters)

• Experience with high-speed interface testing (PCIe, CXL, DDR, Ethernet, or SerDes)

• Strong programming skills in Python for test automation

• Familiarity with Linux operating systems and command-line tools

• Demonstrated experience coordinating with third-party testing laboratories and managing logistics, including sample shipping, chain of custody, and scheduling

• Strong organizational skills for managing multiple RMA cases simultaneously and prioritizing based on severity/impact

Preferred Qualifications

• Experience with post-silicon validation of ASICs, SoCs, or Retimer/PHY products

• Knowledge of analog/mixed-signal circuit testing and debugging techniques

• Experience with JTAG, I2C, SPI, and other embedded interfaces

• Familiarity with PCB design, schematic reading, and signal integrity concepts

• Knowledge of data center systems architecture (servers, AI platforms, networking equipment)

• Understanding of ATE (Automated Test Equipment) systems and production test methodologies

• Experience with defect screening methodologies including visual inspection, electrical testing, and acoustic imaging

• Experience with complete RMA lifecycle management from intake through root cause analysis and corrective action

• Knowledge of common semiconductor failure modes and failure analysis techniques including die attach inspection, delamination detection, void analysis, and crack identification

• Experience with formal compliance testing and industry standards

The base salary range is $160,000.00 USD – $200,000.00 USD. Your base salary will be determined based on your location, experience, and the pay of employees in similar positions.
