About the Role
RadixArk is seeking a Member of Technical Staff — Kernel / Compiler / Communication to push the limits of performance for frontier AI systems.
You will work at the lowest layers of the stack — kernels, runtimes, compilers, and communication libraries — to unlock maximum efficiency from modern accelerators and interconnects.
This role is critical to scaling training and inference across thousands of GPUs, where microseconds and memory bandwidth matter. Your work will directly shape the performance envelope of next-generation AI systems.
This is a deeply technical role for engineers who enjoy working close to hardware and solving performance problems that most engineers never encounter.
Requirements
5+ years of experience in systems, compiler, or performance engineering…
