Principal Compiler Architect - Technical Leadership

Meta is seeking a principal-level Compiler Architect to work across the full compiler stack for MTIA (Meta Training and Inference Accelerator). In this role, you will design and implement compiler infrastructure that enables efficient code generation, optimization, and execution on Meta's custom AI accelerators — from high-level graph transformations through intermediate representations to low-level code generation. You will tackle the hardest compiler challenges spanning ML workload analysis, graph-level optimizations, memory hierarchy management, and hardware-software co-design. This is a role for engineers who build the foundational software stack that unlocks the full performance potential of custom silicon for large-scale AI workloads.
