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 Principal 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 Principal DFT Engineer, you will provide technical leadership across the full DFT lifecycle—from architecture and specification through implementation, verification, and silicon bring-up. You will define and drive DFT strategy, establish robust methodologies, and lead execution to ensure high test quality and manufacturability. This role requires deep expertise, cross-functional influence, and the ability to drive DFT excellence across projects and teams.

This is a critical leadership position with high impact on first-pass silicon success and production quality for next-generation AI connectivity solutions.

Key Responsibilities

DFT Architecture & Technical Leadership

• Define and own DFT architecture for complex SoCs, including Scan, MBIST, LBIST, JTAG/iJTAG, and ATPG strategies
• Lead DFT planning, specification, and quality tracking across the project lifecycle
• Provide technical leadership and drive DFT sign-off readiness to ensure successful tapeout
  
  

• Lead DFT implementation, integration, and verification at block, full-chip and chiplet levels
• Own end-to-end DFT activities from specification through silicon bring-up and production support
• Ensure high test coverage, robust pattern generation, and alignment with manufacturing requirements
  
  

• Develop and drive scalable DFT methodologies, flows, and automation frameworks
• Collaborate closely with RTL, Physical Design, STA, and Test Engineering teams to ensure design-for-test readiness
• Optimize DFT integration across front-end and backend flows to improve quality, PPA, and turnaround time
  
  

• Bachelor’s degree in Electrical Engineering or related technical field (Master’s preferred)
• 12+ years of experience in DFT design, implementation, and verification for complex ASIC/SoC designs
• Proven experience in leading DFT activities across full chip development cycles
• Deep expertise in DFT techniques including Scan, MBIST, LBIST, JTAG/iJTAG, and ATPG
• Strong understanding of DFT and Physical Design flows, including timing implications and integration challenges
• Experience with industry-standard DFT tools (Siemens Tessent, Synopsys TestMAX or equivalent)
• Solid experience with DFT verification methodologies and coverage analysis
• Strong scripting skills (Tcl, Python, or Perl) for automation and flow development
  
  

• Experience with advanced process nodes (7nm and below)
• Background in high-speed connectivity designs (PCIe, Ethernet, CXL, or similar)
• Experience with hierarchical DFT methodologies and large multi-die or chiplet-based systems
• Knowledge of silicon bring-up, production test flows, and yield optimization
• Familiarity with STA, low-power design, and CDC as it relates to DFT integration
• Strong leadership and communication skills, with ability to influence cross-functional teams globally
