Role Overview

Astera Labs is establishing a strategic R&D center in Israel to drive the development of complex semiconductor chips that solve the critical 'data bottlenecks' enabling the future of AI at scale. As we expand our presence in Israel, we're seeking a visionary Senior DFT Engineer to help build our local engineering powerhouse from the ground up. This is a unique opportunity to take on meaningful product ownership in a new site, ensuring the reliability and testability of chips that power the world's largest AI clusters.

As a Senior DFT Engineer at Astera Labs, you will be at the intersection of architecture, design, and production. You won't just run tools—you will be a foundational member of the team responsible for the entire lifecycle of our silicon's reliability. From defining initial DFT architecture to supporting post-silicon bring-up, your work ensures that the backbone of AI infrastructure connectivity is flawless and scalable. If you thrive on solving complex challenges in deep-submicron processes and want to establish world-class DFT methodologies, this is your opportunity.

Key Responsibilities

  • DFT Architecture & Strategy

    • Own the DFT journey from high-level architecture definition and RTL design to backend implementation and post-production support
    • Develop comprehensive Design-for-Testability (DFT) strategies for next-generation connectivity platforms, ensuring chips meet the highest quality standards
    • Define DFT architectures including JTAG/iJTAG, MBIST, Scan, and ATPG methodologies

  • Test Pattern Development & Optimization

    • Generate and optimize high-quality test and debug patterns for production
    • Perform Static Timing Analysis (STA) for DFT modes and conduct gate-level simulations to ensure robust performance
    • Drive test coverage and quality metrics to meet stringent manufacturing requirements

  • Cross-Functional Collaboration & Methodology Innovation

    • Act as a multidisciplinary bridge, collaborating closely with Architecture, Verification, and Backend teams to ensure seamless integration and optimal QoR
    • Participate in developing and maintaining cutting-edge DFT implementation flows
    • Automate and improve methodologies using advanced scripting and tools

Basic Qualifications

  • Bachelor's degree in Electrical Engineering or related technical field
  • 3+ years of hands-on experience in DFT roles at semiconductor companies
  • Deep expertise in DFT flows and architectures including JTAG/iJTAG, MBIST, Scan, and ATPG
  • Proficiency with industry-standard EDA tools from Synopsys (TestMAX) or Mentor (Tessent)
  • Strong understanding of logic design, verification, debug, and Static Timing Analysis (STA)
  • Scripting proficiency in Tcl, Perl, Python, or Shell for automation and innovation

Preferred Qualifications

  • Master's degree in Electrical Engineering or related field
  • Knowledge of high-speed interface protocols (PCIe, Ethernet, CXL, UALink) and their specific test requirements
  • Experience in chip bring-up and mass production activities
  • Background in advanced process technologies (7nm and below)
  • Excellent communication skills with ability to work effectively in global team environments

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.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
