Job Summary
As a Senior Software Engineer in the ML Software Performance Analysis team, you will play a critical role in ensuring end-to-end performance excellence of our proprietary AI hardware and software stack. You will directly report to the Performance Analysis Team Lead and collaborate closely with component teams, including ML Framework developers, Compiler and Runtime teams, Infrastructure engineers, and Product Management. Your work will directly influence the efficiency and scalability of our ML software solutions, significantly impacting our business by enabling reliable and performant AI solutions for customers.
The Team
The ML Software Performance Analysis team is a part of the wider ML Software Engineering organisation, responsible for delivering optimised, proprietary machine learning solutions. Our team consists of experienced engineers and domain experts focused on rigorous performance benchmarking, in-depth analysis, and cross-layer optimization from single chip to large-scale, distributed systems.
We work closely with both internal partners and external collaborators to ensure our solutions meet the highest standards of performance, efficiency, and scalability.
Our core responsibilities include:
- ML Software Stack Performance Reports – We publish regular reports that provide a comprehensive view of the performance status of the ML software stack
- End-to-End Performance Optimization – We take a holistic approach to performance, ensuring that local optimizations do not lead to global regressions. Our work spans component boundaries, enabling balanced and efficient performance across the entire stack
Responsibilities and Duties
- Own performance analysis across the full ML stack, from model execution down to hardware utilization
- Identify bottlenecks and regression trends using profiling, benchmarking, and deep system analysis
- Drive cross-team optimizations involving frameworks, compilers, runtime, and infrastructure
- Design and maintain benchmarking environments for synthetic, focused benchmarks up to large-scale ML workloads
- Produce performance reports that translate low-level findings into actionable insights
- Ensure local optimizations improve global system performance, not just isolated components
- Partner with engineering teams to guide performance improvements and validate impact
Candidate Profile
Essential:
- A passion for your work and the ability to thrive in uncertain and complex environments
- Strong programming skills in Python/C/C++, with a focus on performance-sensitive applications
- Solid understanding of computer architecture, performance profiling, and low-level system behaviour (CPU, memory, I/O)
- Experience with benchmarking and analysing complex, distributed systems
- Familiarity with Linux-based development environments and tools
- Strong problem-solving skills and ability to interpret and communicate performance data clearly
Desirable
- Knowledge of ML frameworks (ideally PyTorch) and their performance characteristics
- Experience with performance analysis in GPU-accelerated environments (CUDA, ROCm, etc.)
- Familiarity of hardware performance characteristics especially in ML context including high-speed networking (e.g. RoCE, RDMA)
- Familiarity with distributed computing frameworks (ideally collectives experience)
- Experience building dashboards or visualizations for performance monitoring (e.g., Grafana, Prometheus, or custom tooling)
- Exposure to performance regression tracking and CI pipelines for performance validation
Benefits
In addition to a competitive salary, Graphcore offers annual leave policy, medical and dental health plans, a gym card, and employee pension (matched up to 4%). We review our benefits on a yearly basis to ensure we offer a valuable and rewarding benefits programme to our employees. We welcome people of different backgrounds and experiences; we’re committed to building an inclusive work environment that makes Graphcore a great home for everyone. We offer an equal opportunity process and understand that there are visible and invisible differences in all of us. We can provide a flexible approach to interview and encourage you to chat to us if you require any reasonable adjustments.
