Responsibilities
- 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 stuck-at, transition, path delay, and cell-aware 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, reduce manual effort, and enable reuse across chip generations
- Support silicon bring-up activities by analyzing failure data, performing scan diagnosis, and identifying root causes of manufacturing defects
- Contribute to DFT roadmap planning by evaluating emerging test methodologies and recommending improvements to Meta's silicon test strategy
- Provide technical guidance to peers on DFT best practices, design partitioning for testability, and cross-functional trade-off decisions
Minimum Qualifications
- Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience
- 6+ years of experience in DFT engineering for complex ASIC or SoC designs, including scan insertion, ATPG pattern generation, and MBIST implementation
- Experience with industry-standard DFT EDA tools for scan compression, ATPG, and memory test (e.g., Tessent, Synopsys DFT Compiler, TetraMAX)
- Experience achieving high fault coverage targets across multiple fault models (stuck-at, transition delay, cell-aware) 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
Preferred Qualifications
- Familiarity with IEEE 1500, IEEE 1687 (IJTAG), or IEEE 1149.1 boundary scan standards and their application in infrastructure ASICs
- Background in post-silicon failure analysis and yield improvement using scan diagnosis and statistical defect modeling
- Experience with at-speed test methodologies including launch-on-capture and launch-on-shift for timing-critical paths
- Experience with DFT architecture for high-speed SerDes interfaces, mixed-signal IP, or hierarchical test integration in large multi-die or chiplet designs
