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.

Coordinate Validation Across Teams 

• Work closely with Technical Product Owners, Product Managers, engineering teams, and technical leads to manage dependencies and alignment. 

• Coordinate feature validation planning with teams working across ML frameworks, runtime systems, performance tooling, distributed execution, and infrastructure.   

• Help ensure testing, benchmarking, and integration activities are planned early as part of feature development.   
• Facilitate communication between teams to identify risks, blockers, and changing priorities. 

Enable Effective Technical Collaboration
