We are looking for an experienced Silicon Test Engineer to join our Product Test and Diagnosis Department. The role involves implementation of all stages of the silicon test flow for next‑generation AI processors. Working closely with a cross‑functional team you will play a key role in developing ATE test capability in the UK. The ideal candidate should have a focus on quality, demonstrate a good understanding of the importance of production test on the success of a product, a proven ATE test engineering background, and a pragmatic, hands‑on and flexible approach to a fast‑changing environment.

The Product Test and Diagnostics team’s role is to detect and manage hardware defects that arise from the manufacture and use of our products. This covers chips, boards and finished systems and takes place both in the manufacturing sites and in the field.

• Working with the Silicon and DFT teams to define manufacturing test solutions.
• Understanding of top‑level DFT strategies within multi‑die product.
• Defining test fixtures; for ATE Test Solutions: load boards, probe cards, sockets, cooling systems.
• Writing Production, Engineering and Characterisation Test Programs on advanced ATE platforms.
• Producing tests for other stages in the test flow; board, blade, and in‑field test.
• Correlation to bench measurements.
• Transferring test solutions to the far east.
• Work collaboratively with other engineering teams to ensure successful silicon bring‑up and help identify any silicon failures to enhance yield learning and improvement.

• A pragmatic approach, the ability to improvise, pitch in, and get the job done.
• Strong knowledge of digital integrated circuits and advanced test techniques.
• Very good understanding of DFT components such as JTAG (IEEE 1149.x), IJTAG (IEEE P1687), Core Test (IEEE P1500), Die Stack Test (IEEE‑1838), SSN (Streaming Scan Network), Test Compression, BIST, MBIST, etc.
• Understanding of the latest scan test fault models.
• Experience in transferring to volume manufacture in far‑east OSATs.
• 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.
• Proven competence on Advantest A93K testers.
• Experience of SSN and multi‑core parallel testing.
• Experience of thermal control of high‑power devices in a production environment.
• Experience of high voltage stress testing.

In addition to a competitive salary, Graphcore offers flexible working, a generous annual leave policy, private medical insurance and health cash plan, a dental plan, pension (matched up to 5%), life assurance and income protection. We have a generous parental leave policy and an employee assistance programme (which includes health, mental wellbeing, and bereavement support).
