Senior Compiler Optimization Engineer — AI Accelerators We’re working with an AI hardware company building a new compiler and software stack for high-performance accelerated computing. This role sits in the middle of the compiler, transforming models and computational graphs into efficient programs for a new accelerator architecture. You’ll own optimizations that materially affect workload performance rather than maintaining an established toolchain. What you’ll work on
- 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
- Help define how ML workloads should map onto the underlying hardware What we’re looking for
- 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 Experience with PyTorch compilation, Triton, GPUs, AI accelerators, memory optimization or hardware/software co-design would be particularly valuable. This is an opportunity to shape a compiler while both the software stack and target architecture are still evolving.
