About the Job

Requirements

  • A Bachelor's degree and 5 years of related experience, a Master's degree and 3 years of related experience, a PhD and 0 years of related experience, or equivalent related work experience.
  • Experience with ASIC DFT implementation or validation.
  • Experience with industry DFT tools such as Siemens Tessent, Synopsys DFT Compiler/TestMAX, or equivalent.
  • Experience with scan architecture, scan compression, ATPG, MBIST, OCC, and test-mode controls.
  • Experience with stuck-at and transition fault models.
  • Experience debugging DFT rule violations, scan-chain issues, ATPG coverage gaps, and pattern simulation failures.
  • Scripting experience using Tcl, Python, Perl, or shell.

Responsibilities

  • Support DFT implementation for ASIC / SoC blocks and subsystems.
  • Implement and validate scan insertion, scan compression, OCC, MBIST, boundary scan, and related DFT logic.
  • Run DFT rule checks and debug scan, clock, reset, and test-mode issues.
  • Generate and validate ATPG patterns for stuck-at, transition, and other required fault models.
  • Analyze test coverage, pattern count, compression results, and ATPG reports.
  • Debug DFT DRC violations, ATPG coverage holes, chain failures, and pattern simulation issues.
  • Work with RTL and verification teams to ensure DFT requirements are correctly implemented.
  • Support block-level and full-chip DFT integration activities.
  • Assist with hierarchical DFT flows, pattern retargeting, and validation where applicable.
  • Develop and maintain Tcl, Python, Perl, or shell scripts to automate DFT flows and reporting.
  • Support silicon debug, diagnosis analysis, and yield-learning activities as needed.
  • Document DFT implementation results, known issues, waivers, and signoff status.

Desired Qualifications

  • Experience with hierarchical DFT methodology and block-level signoff.
  • Exposure to IJTAG / IEEE 1687, IEEE 1500, boundary scan, or SSN-based flows.
  • Experience with MBIST insertion, memory test validation, or BISR flows.
  • Familiarity with gate-level simulation, SDF timing, and pattern validation.
  • Exposure to silicon bring-up, ATE pattern delivery, failure diagnosis, or yield debug.
  • Experience working on advanced-node ASICs, networking ASICs, or high-performance SoCs.
  • Ability to improve automation, regression checks, and DFT reporting dashboards.
  • Experience with clocking, reset, timing constraints, and multi-clock-domain scan implementation.
  • Scripting experience using Tcl, Python, Perl, or shell.
  • Experience troubleshooting problems related to ASIC DFT and working with cross-functional teams.

About the Company

Cisco

Makes networking gear and security software

Cisco makes the switches and routers that connect offices, data centers, and cloud services, and it also sells cybersecurity tools and Webex video meetings to businesses and governments. It was one of the first companies to sell routers that let different kinds of computer networks exchange data, and in 2000 it briefly became the world's most valuable company. Customers run its network gear, from Wi-Fi access points to AI data center systems, with Cisco software that sets up and secures the network, while its Splunk unit searches computer logs to catch outages and attacks. Cisco earns money from hardware sales, software subscriptions, and support contracts. It was founded in 1984 and is based in San Jose, California.
