Principal DFT Engineer

Astera Labs is seeking a hands-on Principal DFT Engineer to drive DFT architecture and execution for its signal-conditioning products that enable high-speed connectivity in rack-scale AI infrastructure. This is an individual-contributor role focused on technical ownership and delivery.

The role can expand into a people-management path for the right candidate. We are advertising at the Principal individual-contributor level and remain open to discussing a management track where it is a strong fit.

You will own day-to-day DFT work while partnering with design, verification, physical design, packaging, product engineering, and manufacturing teams. The focus is advanced multi-die designs, with emphasis on test coverage, diagnostics, yield, and production readiness for high-speed PCIe and Ethernet products. You will diagnose complex DFT integration and tool-related issues, reason through unfamiliar problems, and help the Toronto team build capability for future multi-die programs.
