* Generate and deliver ATPG test pattern for stuck-at, transition, cell aware and path delay fault models, drive scan-based diagnosis methodology for Silicon failure debug, and provide post-silicon testing and validation support

* Responsible for evaluating design readiness for scan insertion through RTL and physical design Scan Design Rule Check (DRC) tools

* Integration and verification of Design for Test (DFT) fabrics and IP within Subsystems

* Perform simulation runs and debug for non-timing and back annotated timing (SDF) gate level simulations

* Develop test scripts, automate processes, and analyze data using programming languages such as Python, Tcl, or C++

Minimum Qualifications:

* Bachelors + 8 years of related experience, or Masters + 6 years of related experience, or PhD + 3 years of related experience

* Prior experience working with ASICs

* Prior experience in scan insertion and DFT setup, integration and validation
