Founded just over three years ago, Graphcore's growth and impact has been little short of staggering. We believe we're in a unique position as a new wave of machine learning technology begins to emerge. We see a world where technology enhances human potential and takes us into a new era of intelligence and progress that everyone can benefit from.

What we can achieve over the next few years will re-shape businesses around the world.

Graphcore has created a completely new processor, the Intelligence Processing Unit (IPU), specifically designed for artificial intelligence. The IPU’s unique architecture means developers can run current machine learning models orders of magnitude faster. More importantly, it lets AI researchers undertake entirely new types of work, not possible using current technologies, to drive the next great breakthroughs in general machine intelligence.


As a Senior Verification Engineer at Graphcore you will be responsible in ensuring that our IPU performs in accordance with its specification and that its implementation is similarly accurate. You will be familiar with modern CPU and ASIC verification methodologies including, but not limited to constrained random test generation and functional coverage.

The Verification team at Graphcore interacts closely with Architects, RTL designers and Software Tool chain engineers, you will be fluent in their languages and work efficiently with them to determine the root causes of complex issues. You will be able to describe these issues accurately and concisely when filing bug reports.

You will be comfortable with working at scale. Not only logically within our IPU but also keeping our large simulation farm busy with a continuous flow of verification tasks prospecting for issues and closing coverage.

Additionally, as a Senior Verification Engineer you will mentor and lead the younger team members and help foster a deep understanding of contemporary verification processes.

Finally you will add value to our verification infrastructure by adding useful features and improving throughput.


  • Verification planning, specification of functional coverage
  • Providing feedback to architects
  • Test generation and failure diagnosis/triage
  • Contributing to shared verification infrastructure
