About the Role

We are building an MLIR-based compiler and inference stack for custom AI silicon used in telecommunications baseband processing. The compiler takes ML models from StableHLO through orchestration, tiling, memory planning, and code generation onto a multi-core processor architecture with custom accelerators. This is a small team building something real, not a research project. You will design and implement MLIR passes, debug IR transformations, optimize for real hardware constraints, and contribute wherever the hardest problems are, whether that is model import, scheduling, memory allocation, or code generation. You will work directly with hardware architects, runtime developers, and AI researchers, and you will help shape the compiler as it matures.

Responsibilities

Design and implement MLIR transformation passes, dialect conversions, and lowering pipelines
Work on tiling, scheduling, vectorization, and memory-planning problems specific to the target hardware
Debug numerical correctness issues across compiler transformations
Develop and maintain compiler testing and validation infrastructure
Contribute to hardware-software co-design discussions as the compiler matures
Profile, analyze, and optimize compiled workloads on silicon
Own the design and implementation of significant compiler subsystems

Requirements

Strong C++ development experience
Hands-on experience with MLIR, LLVM, or another production compiler framework
Experience implementing compiler passes or transformations at production quality
Understanding of intermediate representations and compiler pipelines
Ability to work across abstraction layers, from ML operator semantics to hardware constraints
Track record of owning technical work end-to-end, from design through delivery
StableHLO, XLA, JAX, PyTorch, or ONNX model lowering
Custom MLIR dialect development
DSP, VLIW, or AI accelerator compilation
Static scheduling or software-managed memory
Tiling, loop transformations, or data-layout optimization
Quantization or mixed-precision lowering
Bare-metal or embedded runtime integration
Strong compiler engineers who can learn new problem domains quickly
