Overview
Senior Back End DFT Engineer at Graphcore.
We are looking for an experienced Back End DFT Engineer to join our Product Test and Diagnosis Department. The role requires an understanding of DFT structures and strategies used in next-generation AI processors, as well as generating test patterns to meet coverage, quality, and power budget targets. Test patterns will be targeted at a range of target test systems throughout the product life cycle: Wafer Sort, Final Test, Board Test, System Test and In-Field. The ideal candidate will have a DFT or ATE Test Engineering background and a pragmatic, hands-on approach in a fast-changing environment.
The Product Test and Diagnostics team detects and manages hardware defects that arise from manufacture and use of our products, spanning chips, boards and finished systems, across manufacturing sites and in the field.
Responsibilities
* Working with the Silicon and DFT teams to define manufacturing test solutions.
* Understanding top level DFT strategies within multi-die product.
* Generation and retargeting of structural test vectors, fault coverage analysis and improvement.
* Use of Tessent for pattern debug/diagnostics on the bench.
* Conversion of patterns to a variety of test platforms.
* Work with the product and test engineering teams to ensure successful silicon bring-up and help identify any silicon failures to enhance yield learning and improvement.
Candidate Profile
* Essential
* A pragmatic approach, the ability to improvise, pitch in, and get the job done.
* Very good knowledge of Digital Integrated Circuits and Systems.
* Very good understanding of DFT components like JTAG (IEEE 1149.x), IJTAG (IEEE P1687), Core Test (IEEE P1500), Die Stack Test (IEEE-1838), SSN (Streaming Scan Network), Test Compression, OCC, etc.
* Experience in Scan based testing and industry standard ATPG tools.
* Exposure to silicon bring-up, post-silicon testing and tester pattern debugging.
* Experience in Production Test and ATE test.
* Ability to work within high pressure cross-department and cross-company teams.
* Ability to mentor junior members of the team.
* Strong scripting and debugging skills using programming languages like Python, TCL, Perl, Shell, etc.
* Degree level qualifications in Electronics or a related field.
* Good communication skills.
Desirable
* Experience of SSN and multi-core parallel testing.
* Experience of pattern conversion to ATE platforms.
* Experience of Advantest or Teradyne test systems.
