Role Overview

This role will lead day-to-day DFT architecture and execution for Astera Labs' signal-conditioning products, helping deliver highly testable, high-quality silicon for rack-scale AI infrastructure. You will partner with design, verification, physical design, packaging, product engineering, and manufacturing teams to improve coverage, yield, diagnostics, and production readiness across advanced multi-die products.

As Astera Labs scales its purpose-built connectivity platform, you will help establish practical DFT methods for high-speed PCIe and Ethernet signal-conditioning products, with a strong focus on SerDes physical-layer performance, signal integrity, and production robustness. The role offers hands-on technical ownership, opportunities to mentor engineers, and direct influence on products that keep next-generation AI systems connected, observable, and reliable.

Key Responsibilities

• DFT Architecture & Planning

  • Define DFT plans for signal-conditioning products supporting high-speed PCIe and Ethernet connectivity and advanced multi-die packaging configurations.

  • Develop test-access, coverage, observability, and diagnostic strategies for die-to-die interfaces, interposers, and package-level integration.

  • Partner with design and physical design teams to balance DFT area, timing, routing, and manufacturability.

• DFT Implementation & Silicon Readiness

  • Drive scan insertion, ATPG, compression, MBIST, LBIST, JTAG/IJTAG, and high-speed SerDes BIST requirements.

  • Establish coverage targets and review ATPG results, pattern quality, test time, and ATE cost.

  • Support tape-out, wafer sort, packaged-device test, silicon bring-up, characterization, and production ramp.

• Quality, Yield & Diagnostics

  • Collaborate with product, manufacturing, assembly, and test engineering on yield learning, failure analysis, and root-cause resolution.

  • Develop pre-bond, post-bond, and package-level test approaches for known-good-die screening and advanced packaging.

  • Improve diagnostic capabilities for silicon, package, and system-level issues.

• Technical Leadership & Collaboration

  • Mentor DFT engineers and coordinate execution across product development milestones.

  • Partner with OSATs, ATE vendors, packaging partners, and internal stakeholders to resolve technical issues and maintain schedules.

  • Communicate risks, trade-offs, and recommendations clearly to cross-functional teams.

Basic Qualifications

• Bachelor’s degree in Electrical Engineering, Computer Engineering, or a related field.

• 10-15 years of experience in Digital Design engineering or related semiconductor design and test work.

• Hands-on experience with scan, ATPG, compression, MBIST, LBIST, JTAG, and/or IJTAG methodologies.

• Understanding of the ASIC design flow from RTL through GDS and DFT signoff.

• Experience with DFT EDA tools such as Synopsys DFT Compiler, TetraMAX, DFTMAX, Siemens Tessent, or equivalent.

• Understanding of high-speed signal conditioning, SerDes physical-layer behavior, signal integrity, die-to-die connectivity, or advanced packaging test requirements.

Preferred Qualifications

• Master’s or PhD in Electrical Engineering, Computer Engineering, or a related field.

• Experience with 2.5D or 3D integration, silicon interposers, TSVs, hybrid bonding, micro-bumps, chiplets, or known-good-die strategies.

• Knowledge of IEEE 1838, IEEE 1149.1, IEEE 1687, and relevant JEDEC standards for multi-die testing.

• Experience with PCIe, Ethernet, UALink, and high-speed SerDes physical-layer validation or test.

• Familiarity with ATE platforms, wafer probe, OSAT engagement, production test economics, and yield analysis.

Salary range is CAD $198,000 to CAD $220,000 depending on experience, level, and business need. This role may be eligible for discretionary bonus, incentives and benefits.
