Senior ML Systems Engineer - Simulations

We are looking for a Senior ML Systems Engineer to build and validate simulation infrastructure for large-scale machine learning systems.

This role focuses on modelling the compute and communication behaviour of systems used for ML training and inference, and using simulation to guide architecture, performance optimization, and capacity planning.

The ideal candidate combines strong systems experience with hands-on experience in measurement, benchmarking, and performance analysis of modern ML systems.

• Build simulation models for compute, memory, interconnect, and communication behavior in ML systems.
• Develop tools to simulate performance for training and inference workloads.
• Model distributed execution across accelerators, hosts, and network fabrics, including collectives, synchronization, and communication bottlenecks.
• Use simulation and analytical modelling to evaluate tradeoffs, identify bottlenecks, and guide system design.
• Run performance experiments and benchmarks on real ML systems to calibrate and validate simulation models.
• Analyze end-to-end performance, including throughput, latency, scaling efficiency, utilization, and cost/performance tradeoffs.
• Partner with hardware/software/Networking/ML teams to align simulation with real workloads and constraints.
• Create reproducible benchmarking methodologies across models, system configurations, and compare against real system measurements to prove validity.
• Communicate findings through technical reports and design recommendations.

• Master’s, or PhD in Computer Science, Electrical Engineering, Computer Engineering, or a related field.
• Strong experience in ML systems, distributed systems, performance engineering, computer architecture, or simulation.
• Understanding of systems used for machine learning training and inference.
