Job description
At d-Matrix, we are focused on unleashing the potential of generative AI to power the transformation of technology. We are at the forefront of software and hardware innovation, pushing the boundaries of what is possible. Our culture is one of respect and collaboration.
We value humility and believe in direct communication. Our team is inclusive, and our differing perspectives allow for better solutions. We are seeking individuals passionate about tackling challenges and are driven by execution. Ready to come find your playground? Together, we can help shape the endless possibilities of AI.
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
