Role

Role: Compiler Engineer (mid, senior, staff)

About the Company

An AI Infrastructure Start-up (B2B SaaS) are building a next-generation platform and seeking Mid/Senior/Staff Compiler Engineers.

Their LLVM/MLIR-based pipeline delivers lower latency, higher throughput, and improved cost efficiency across GPUs, enabling teams to scale production AI without scaling the bill.

Responsibilities

• Designing and extending MLIR dialects, building conversion pipelines.
• Implementing and optimising passes.
• Extending and maintaining backends, curating and writing custom kernels (CUDA/HIP) with runtime integration for optimal occupancy and bandwidth use.
• Profiling, measuring, and preventing regressions using tools such as nsight-compute, rocprof, vtune, and perf, supported by CI’d performance suites.
• Driving upstream improvements to LLVM/MLIR, authoring RFCs, and reviewing PRs.
• Collaborating with model optimisation and runtime teams on ABI, graph partitioning, and kernel launch strategies.
• Experience with LLVM and/or MLIR.
• 3+ years’ experience in production compiler or toolchain development (LLVM/MLIR, GCC, IREE/XLA/TVM, etc.).
• Expertise in C++17/20.
• Strong understanding of GPU architecture.
• Proven performance engineering skills.

Compiler Engineer Desirable Experience

• Exposure to IREE, OpenXLA/XLA, TVM, TensorRT-LLM, or Glow.
• Knowledge of quantisation (INT8/INT4), dynamic shapes, and autotuning.
• Familiarity with CPU vectorisation (AVX2/AVX-512/SVE), register allocation, or polyhedral techniques.
• Experience with FPGA/HLS flows or custom accelerator backends.

Why Join

• Opportunity to take ownership of critical compiler subsystems with visible upstream impact.
• Work on one of the most complex and valuable challenges in AI, translating FLOPs into real-world performance.
• Contribute to reducing compute costs, lowering CO₂ emissions, and easing demand on the global power grid.
• Competitive compensation* and growth opportunities within a fast-paced, highly technical team.

Seniority and Employment Details

• Seniority level: Mid-Senior level
• Employment type: Full-time
• Job function: Information Technology
• Industries: Software Development
