We are building the first Neuron performance engineering team in Tel Aviv. As a Machine Learning Performance Engineer, you'll help shape the direction of this team from the ground up - profiling and optimizing workloads across the full ML software stack, writing high-performance kernels, and improving the Neuron SDK that external developers depend on. You'll work at the boundary between software and hardware, collaborating directly with compiler, runtime, and chip design engineers to close performance gaps customers care about.The team is new and small, which means broad scope, direct ownership, and real influence over the technical direction we take.
If you enjoy digging into performance bottlenecks and turning analysis into measurable wins, this role is for you.Key job responsibilitiesDesign and implement high-performance compute kernels for ML operations, leveraging the Neuron architecture and programming models.Profile ML workloads end-to-end to identify bottlenecks - memory, compute, or communication - and drive optimizations through to a measured improvement.Enhance the programming model and tooling that kernel and model developers rely on, improving usability and debugging workflows.Identify and drive optimization opportunities across the Neuron software stack (compiler, runtime, frameworks).Document software designs, operational runbooks, and performance findings so the broader team can build on your work.A day in the lifeYou might start your morning reviewing profiling data from a customer's large diffusion model training job, tracing a utilization gap back to a specific kernel. After a design discussion with compiler engineers about a new operator fusion strategy, you spend the afternoon writing and benchmarking a kernel prototype. Later, you review a teammate's pull request for a runtime optimization and share your findings in a short write-up for the broader Neuron organization.
Your work directly translates into faster model execution and lower cost for AWS customers running ML workloads at scale.Requirements: Basic Qualifications- 3+ years of non-internship professional software development experience.
