Graphcore’s Hardware Engineering Team creates both products for sale in volume production and hardware test & validation systems based on Graphcore’s IPU processor. These systems allow Graphcore’s customers to develop leading-edge machine-learning solutions for training and inference.

What you’ll be doing (production systems):

• Circuit design, requirements analysis, functional definition, and component selection.
• PCB Layout constraint definition, and support of PCB CAD layout team.
• Circuit validation and verification.
• Design and running of tests to validate circuit performance and margin.
• Debugging and optimisation, in collaboration with the firmware team, of the correct system performance of microcontroller hardware control code.
• Support of transfer to mass production.

What you’ll bring:

We appreciate not everyone will meet all of the criteria. If you meet most of the requirements below and believe you can bring value to this role, we’d love to hear from you.

• Essential experience:
• Knowledge of DCDC voltage (including multi-phase) regulators, linear regulators and PCB design requirements for efficient power delivery.
• Processor system development, as STM32, with experience in processor interfaces such as Ethernet, PCIe, DDR, FLASH, USB, I2C, SPI, JTAG etc.
• Experience in SERDES (eg 112Gbps, PAM4) a benefit.
• Other experience required:
• Demonstrable experience in digital circuit development and validation.
• Familiar with bringing up, debugging and validating designs.
• Knowledge and use of high‑speed digital oscilloscopes, logic analysers and signal generators.
• Experience in scripting (Linux, Python, Bash) of tests and Excel to analyse results.
• Experience of document management and record keeping.
• Experience in Mentor (or similar) PCB design flow for schematic capture, design constraints, PCB layout.
