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 Physical Design 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, defining the backend execution and methodologies for chips that power the world's largest AI clusters.

As a Physical Design Engineer, you will be a key architect of our silicon's physical reality. You won't just execute a flow—you will help establish our local execution culture and technical standards, owning the transformation of complex logic into high-performance silicon. You will drive the physical implementation journey from synthesis through signoff, ensuring our connectivity solutions meet the extreme performance, power, and area targets required for next-generation AI infrastructure. If you thrive on solving complex challenges in deep-submicron processes and want to shape the backend methodology for AI infrastructure connectivity, this is your opportunity.

Key Responsibilities

  • Physical Implementation & Execution

    • Be part of the founding Backend team in Israel, playing a critical role in establishing local execution culture and technical standards
    • Take full responsibility for physical implementation journey including Synthesis, Floorplanning, Place & Route, and Clock-Tree Synthesis (CTS)
    • Own macro-level implementation with deep hands-on experience in floorplanning and complex routing

  • Signoff & Design Integrity

    • Drive final stages of design integrity, owning Timing signoff (STA), Physical Verification (DRC/LVS), and Reliability analysis (EMIR)
    • Ensure first-pass silicon success through rigorous signoff flows and analysis
    • Apply Logic Equivalence Checking (LEC) and other verification techniques to guarantee design correctness

  • Methodology Development & Cross-Functional Collaboration

    • Participate in defining and refining Backend methodologies with autonomy to improve workflows and tool automation
    • Work closely with Architecture, Design, and DFT teams to navigate challenges of advanced process nodes and high-speed connectivity
    • Leverage scripting and automation to make engineering environment faster and more robust

Basic Qualifications

  • Bachelor's degree in Electrical Engineering or related technical field
  • 3+ years of hands-on experience in Physical Design at semiconductor companies
  • Proven expertise in the full RTL2GDS flow with deep hands-on experience in macro-level implementation, floorplanning, and complex routing
  • Experience working with advanced process technologies (7nm and below)
  • Solid experience with signoff tools and flows including STA, Logic Equivalence Checking (LEC), DRC, and EMIR analysis
  • Proficiency in TCL or Python scripting to drive EDA tool flows and automate repetitive tasks

Preferred Qualifications

  • Experience with full-chip level implementation and integration
  • Knowledge of Power and Noise analysis (SI/PI) to optimize high-performance silicon
  • Familiarity with Design-for-Test (DFT) requirements and their impact on physical layout
  • Experience with industry-standard EDA tools (Synopsys Fusion Compiler/ICC2, Cadence Innovus)
  • Background in high-speed interface designs or connectivity protocols

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.
