• Fluency in test scripting languages. Including Pyhton and LabView
• Self-starter
• Strong written and oral communications, team-working and interpersonal skills

Desirable

• We are looking for a high-quality Test Development Engineer to complement our existing team
• You will be working closely with the hardware and software development teams to develop and maintain test systems in support of preproduction test solutions
• You will report to the Hardware test team lead, the test team is embedded within the Hardware team
• We want people who work collaboratively and proactively within our teams
• Our engineers are not siloed, and they are trusted and encouraged to take ownership of their tasks and develop test solutions that meet our requirments
• We value team players and the right characteristics are more important than academic qualification or specific experience
• Candidates will be expected to work closely both with other teams within Graphcore and with 3rd party support engineers/contractors, ensuring good communication between all parties, and to contribute meaningfully to the overall efficiency and success of the Hardware Team
• The Hardware test team are part of a larger Hardware team that consistest of Signal Integrity (SI), Mechanical, layout, package and Hardware engineers
• The Hardware team is responsible for delivering state of the art accelerators for machine learning and collaborates with the Silicon, Firmwear and Production teams during product development
• A successful candidate will work within Hardware Engineering Team to define test methods, specify suitable test equipment and automate test systems
• The team is currently responsiable for testing, debugging and characterising high speed serial links, power suppies that can deliver high current and adapt to fast transients
• We also debug and characteratize slower speed protocols like JTAG , I2C I3C and low level PCBA debug
• Developing a deep understanding of Graphcore hardware and software products and how to operate them in a test environment is essential for this position
• You will be expected to understand relevant industry performance test standards, data analysis and presentation systems
• Contributions are expected to span multiple areas and involve:
• Manual testing and debug of complex high speed SERDES which include PCIe Gen 6 and 112/224Gb PAM4 ethernet. This will require the use of high bandwidth oscilloscopes, BERTs and VNA’s, and the ability to understand complex IEEE standards
• Designing and developing graphical user interfaces for controlling our products in a test environment
• Development of test systems for Graphcore’s Machine Learning Accelerator products at a system and board level
• Transfer of preproduction test system knowledge to the production test team
• Test coverage analysis and improvement
• Maintaining and development of our characterisation systems
• Automating tests In either Python or LabView
