Location:

Remote/Hybrid (working on-site at our Toronto, Ontario, Canada office 2 days per week)

Role: Compiler Software Engineer, Staff

What You Will Do:

The d-Matrix compiler team is looking for exceptional candidates to help develop the front end of our machine learning compiler. The successful candidate will work on designing, optimizing, and lowering high-level machine learning representations to intermediate representations suitable for further compilation.

We are particularly interested in candidates who can contribute to

• High-level IR transformations (e.g., graph optimization, operator fusion, canonicalization)

• Dialect and IR design for machine learning frameworks

• Lowering and transformation of ML models from frameworks such as PyTorch, TensorFlow, and ONNX to compiler IRs such as MLIR and LLVM

• Performance optimization for compute graphs, including operator specialization, fusion, and memory layout transformations

• Model partitioning techniques, including

  • Graph-based parallelism strategies (e.g., pipelined model parallelism, tensor parallelism, and data parallelism)

  • Automatic partitioning of large models across multiple devices using techniques like GSPMD (Generalized SPMD Partitioning)

  • Placement-aware optimizations to minimize communication overhead and improve execution efficiency on distributed hardware

The successful candidate will join a team of experienced compiler engineers and work closely with ML framework developers, hardware architects, and performance engineers to ensure efficient model execution.

What You Will Bring:

• Minimum Qualifications:
  Bachelor's degree in computer science or a related field with 6+ years of relevant industry experience (or MS with 5+ years of experience or PhD with 3+ years of experience)

• Strong proficiency in modern C++ (C++14/17/20) and compiler development.

• Experience with modern compiler infrastructures such as LLVM, MLIR, or equivalent frameworks

• Experience with machine learning frameworks (e.g., PyTorch, TensorFlow, ONNX).

• Solid understanding of graph-level optimizations and IR transformations in ML compilers

• Experience with model partitioning strategies such as GSPMD, Sharding, and Distributed Execution

Preferred Qualifications:

• Algorithm design experience, from conceptualization to implementation

• Experience with Open-Source ML compiler projects, such as Torch-MLIR, IREE, XLA, or TVM

• Experience with automatic differentiation, shape inference, and type propagation in ML compilers

• Experience optimizing distributed execution of large models on accelerators (e.g., GPUs, TPUs, custom AI hardware)

• Passion for working in a fast-paced and dynamic startup environment
