Job summary

Join a well-funded pioneering startup building a new software platform for heterogeneous compute. The company is developing a complete compiler and runtime stack that allows AI workloads to run efficiently across different processors without being locked into a single hardware vendor. Its technology spans graph-level optimisation, intermediate representations, code generation, runtimes and low-level performance, bridging modern ML frameworks with GPUs and emerging accelerator architectures. We’re interested in compiler engineers at multiple levels with experience across areas such as: LLVM, MLIR or custom compiler infrastructures Graph compilers, computational graphs and IR optimisation Code generation, instruction selection and backend development Compiler runtimes and heterogeneous execution PyTorch, Triton or other ML frameworks C++ development and computer architecture HW–SW co-design for GPUs or custom accelerators
