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 are looking for a Physical Design CAD Engineer with at least 3 years of hands-on experience in digital implementation flows. The ideal candidate is highly technical, curious, and eager to drive innovation by combining strong physical design knowledge with modern automation and GenAI-based methodologies.

This is a unique opportunity to take on meaningful technical ownership in a new site, implementing the parasitic extraction (PEX) methodologies and flows for chips that power the world's largest AI clusters. As a foundational member of the team, you will be responsible for the accuracy and efficiency of our extraction environment, ensuring that our high-speed designs are modeled with the highest precision from RTL to GDSII.

Key Responsibilities

The Engineer will develop, maintain, and improve CAD flows and methodologies for physical design teams, supporting advanced implementation stages from synthesis through place and route, timing closure, power optimization, and signoff readiness.

Key responsibilities include:

Develop and support physical design CAD flows using industry-standard EDA tools
Build automation infrastructure for implementation, analysis, reporting, and debug
Support design teams in areas such as synthesis, floorplanning, placement, CTS, routing, timing, power, and physical verification
Create scripts and utilities to improve productivity, quality of results, and flow robustness
Support and enhance flows based on Synopsys Fusion Compiler
Explore and integrate GenAI solutions to accelerate debug, automate repetitive tasks, improve reporting, and enhance engineering productivity
Analyze tool results, logs, QoR metrics, timing reports, congestion, utilization, power, and design-rule issues

Basic Qualifications

At least 3 years of experience in Physical Design, CAD, or implementation methodology
Strong understanding of digital physical design concepts, including synthesis, placement, CTS, routing, timing closure, and physical verification
Hands-on experience with Synopsys Fusion Compiler
Experience with scripting languages such as Tcl, Python
Ability to develop automation around EDA tools and large-scale design flows
Good understanding of timing, power, congestion, floorplanning, and QoR analysis
Strong debugging and problem-solving skills
Ability to work closely with multiple engineering teams and support complex design environments
High motivation to learn and apply GenAI technologies in semiconductor design flows.

Preferred Experience

Experience with additional tools such as PrimeTime, StarRC, ICC2, Innovus, Voltus, RedHawk, Calibre, or similar
Knowledge of STA, low-power design, UPF, EM/IR, extraction, or signoff flows
Experience building dashboards, regression systems, flow checkers, or automated report analyzers
Familiarity with LLMs, prompt engineering, AI agents, or GenAI-based coding/debug tools
Experience with Git, CI/CD, databases, or cloud-based compute 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.
