The Team
The ML QA team is responsible for validating the machine learning software stack running on Graphcore hardware. The team works across integration testing, feature validation, performance benchmarking, and end-to-end workload testing, covering multiple layers of the software stack including ML frameworks, runtime behaviour, distributed execution, and system-level functionality.
The team collaborates closely with software engineering teams throughout the development lifecycle, helping define validation strategies early and implementing the test coverage required to validate correctness, functionality, scalability, and performance. The ML QA team also owns performance-focused validation, including benchmark execution, regression analysis, and reporting across real-world ML workloads and extracted model subgraphs.
As Technical Product Owner for ML QA, you will help coordinate and prioritise this work, ensuring the team has clear direction, well-defined deliverables, and alignment with wider software roadmap objectives.

Graphcore is a Bristol-based AI semiconductor company founded in 2016 by serial semiconductor entrepreneurs Nigel Toon and Simon Knowles. Toon previously led XMOS and Picochip, while Knowles co-founded Element14 (acquired by Broadcom) and Icera (acquired by NVIDIA for $435M). The company developed Intelligence Processing Units (IPUs), novel AI accelerators designed from the ground up for machine learning workloads, alongside the proprietary Poplar graph programming framework. Graphcore raised $767M in total funding, reaching a $2.77B valuation, with backing from Sequoia Capital, Atomico, Amadeus, Microsoft, and others. In July 2024, SoftBank Group acquired Graphcore for approximately $500M to $600M. The company continues to operate from Bristol with plans to expand its UK headcount to 750.
