Meta is seeking an ASIC Engineer specializing in Design for Test (DFT) to join their Infrastructure Silicon team. This role focuses on architecting and implementing testability solutions for complex ASICs used in Meta's data centers. The engineer will define DFT strategies from RTL through silicon bring-up, ensuring high fault coverage and manufacturability. Collaboration with design, physical implementation, and validation teams is essential to meet quality and time-to-market targets.

• 6+ years of experience in DFT engineering for complex ASIC or SoC designs, including scan insertion, ATPG pattern generation, and MBIST implementation.
• Experience achieving high fault coverage targets across multiple fault models on multi-million gate designs.
• Experience supporting silicon bring-up and manufacturing test, including ATE correlation and scan-based diagnosis.
• Experience scripting in Tcl, Python, or Perl to develop and maintain DFT automation flows.

• Define and implement comprehensive DFT architectures including scan insertion, ATPG, MBIST, LBIST, and boundary scan for large-scale infrastructure ASICs.
• Develop and drive DFT methodology and flows from RTL through tape-out, including scan compression, test point insertion, and clock domain handling.
• Generate, simulate, and validate ATPG test patterns to achieve target fault coverage across various fault models.
• Collaborate with physical design teams to ensure DFT structures meet timing, area, and power constraints during implementation.
• Partner with silicon validation and manufacturing test teams to define ATE test programs and support post-silicon debug and diagnosis.
• Perform DFT sign-off including fault coverage analysis, test coverage reporting, and DRC/LVS compliance for testability structures.
• Develop and maintain DFT scripts and automation to improve flow efficiency and enable reuse across chip generations.
• Support silicon bring-up activities by analyzing failure data and identifying root causes of manufacturing defects.
• Contribute to DFT roadmap planning by evaluating emerging test methodologies and recommending improvements.
• Provide technical guidance to peers on DFT best practices and cross-functional trade-off decisions.

• Employees at Meta are often offered comprehensive benefits, including medical/dental/vision coverage, mental-health resources, family planning support (fertility, adoption, surrogacy), and caregiving programs. Financial benefits typically include a competitive retirement plan, equity awards, life insurance, and access to financial coaching and legal support. Time-off benefits commonly feature generous PTO and holidays, unlimited sick time, various paid leaves, flexible “Global Travel Days,” and a 30-day paid break every five years.
