Security Architect, Full-Time, Bristol or Cambridge

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.

We believe our IPU technology will become the worldwide standard for artificial intelligence compute. The performance of Graphcore’s IPU is going to be transformative across all industries and sectors whether you are a medical researcher, roboticist or building autonomous cars.

Our team is at the forefront of the artificial intelligence revolution, enabling innovators from all industries and sectors to expand human potential with technology. What we do, really makes a difference.

Graphcore is seeking to hire a Security Architect based in Bristol or Cambridge to join the System Architecture team to define, design and validate security, encryption and root-of-trust hardware and software inside Graphcore’s market leading IPU Machine Intelligence accelerators and within the software and systems around them.
