MLIR/LLVM Compiler Engineer for AI Accelerators

Oho Group; Toronto; On-site; CAD 120,000 - 180,000; Full time

Job summary

Oho Group is seeking a hands-on compiler engineer to join a well-funded startup building a new ML compiler stack for high-performance accelerators. You will work in the middle of the compiler, transforming models into efficient programs for a new accelerator architecture.

You will own optimizations that affect workload performance, design graph and IR-level optimizations, develop passes, and lower workloads through MLIR-based pipelines while collaborating with architecture and runtime teams.

Qualifications

• Strong C++ and compiler engineering experience.
• Hands-on knowledge of LLVM, MLIR or comparable compiler infrastructure.
• Experience with graph optimization, IR transformations or lowering.
• Ability to reason across compiler decisions and hardware behavior.

Responsibilities

• Design graph and IR-level compiler optimizations.
• Develop transformation, fusion, scheduling and memory-planning passes.
• Lower workloads through MLIR-based compilation pipelines.
• Optimize data movement, parallelism and accelerator utilization.
• Analyze generated programs and eliminate performance bottlenecks.
• Collaborate with architecture, code-generation and runtime engineers.
