Compiler Engineer

As a Senior/Principal Compiler Engineer you will help design and implement a greenfield compiler stack for a novel photonic accelerator. You will bridge software and hardware by building representations, lowering and optimization passes, and ensuring production-quality code. You’ll integrate with ML frameworks and cryptography tools, shaping how high-level workloads map to our proprietary target. This role offers technical leadership and influence over the software architecture in a cutting-edge hardware platform. You will collaborate across hardware, simulation, cryptography and algorithms teams to deliver performant, privacy-preserving workloads.

• Design and implement core components of a greenfield compiler stack
• Develop intermediate representations, lowering pipelines and transformation passes
• Build hardware-aware compiler optimisations
• Integrate with technologies such as Google HEIR, PyTorch and ONNX Runtime
• Translate high-level workloads into efficient code for a novel accelerator
• Collaborate with hardware, simulation, cryptography and algorithms engineers
• Benchmark, profiling and debugging of generated workloads
• Influence the technical direction and architecture of the software platform

• Strong professional experience with modern C++
• Hands-on compiler development experience at the IR, middle-end or back-end level
• Experience with MLIR, LLVM IR or another compiler/framework IR
• Knowledge of compiler passes, lowering, optimisation and code generation
• Experience targeting a processor, accelerator or custom architecture
• Interest in hardware-software co-design and building production-quality systems
• MLIR experience ideal but not essential; open to MLIR learners
• Experience with GPU, NPU, DSP, FPGA or custom-silicon compilers
• Cryptography or Fully Homomorphic Encryption experience useful but not required

• collaboration across cross-functional teams
• strong problem-solving and analytical thinking
• effective communication and technical leadership
• modern C++
• compiler development (IR/middle-end/back-end)
• MLIR / LLVM IR
