About the role
Responsibilities
Design and build APIs and runtime components to orchestrate computation and data movement across heterogeneous ML workloads.
Contribute to compiler infrastructure, including the development of optimizations and compiler passes to support evolving hardware.
Engineer and optimize compute and data kernels, ensuring correctness, high performance, and portability across simulation and production environments.
Profile and optimize system bottlenecks, especially around I/O, memory hierarchy, and interconnects, at both local and distributed scales.
Develop simulation infrastructure to validate runtime behaviors, test training stack changes, and support early-stage hardware and system development.
Rapidly deploy runtime and compiler updates to new supercomputing builds in close collaboration with hardware and research teams.
Work across a diverse stack, primarily using Rust and Python, with opportunities to influence architecture decisions across the training framework.
Requirements
Deep curiosity for how large-scale systems work and enjoy making them faster, simpler, and more reliable.
Proficient in systems programming (Rust, C++) and scripting languages like Python.
Experience in one or more of the following areas: compiler development, kernel authoring, accelerator programming, runtime systems, distributed systems, or high-performance simulation.
Excited to work in a fast-paced, highly collaborative environment with evolving hardware and ML system demands.
Value engineering excellence, technical leadership, and thoughtful system design.
Hands-on technician building, testing, and iterating on robotic hardware prototypes in a fast-paced lab environment. Requires strong electromechanical troubleshooting, fabrication, and cross-functional collaboration skills.
