Compiler Engineer

Senior / Principal Compiler Engineer

 Bristol preferred | Fully remote within the UK considered
 Exceptional candidates elsewhere in Europe may also be considered
 Photonic computing | C++ | MLIR | LLVM

I’m supporting a well-funded UK deep-tech company developing a proprietary photonic computing platform for high-performance, privacy-preserving workloads.

They’re looking for a Senior or Principal Compiler Engineer to help build a new compiler stack targeting their novel hardware architecture. You’ll work across compilers, machine-learning frameworks and hardware, translating high-level workloads into efficient code for a proprietary execution target.

What you’ll be doing:

• Designing and implementing core components of a greenfield compiler stack
• Developing intermediate representations, lowering pipelines and transformation passes
• Building hardware-aware compiler optimisations
• Integrating with technologies such as Google HEIR, PyTorch and ONNX Runtime
• Translating high-level workloads into efficient code for a novel accelerator
• Working closely with hardware, simulation, cryptography and algorithms engineers
• Benchmarking, profiling and debugging generated workloads
• Influencing the technical direction and architecture of a growing software platform

What they’re looking for:

• 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 intermediate representation
• Knowledge of compiler passes, lowering, optimisation and code generation
• Experience targeting a processor, accelerator or custom architecture
• An interest in hardware-software co-design and building production-quality systems

MLIR experience would be ideal, but it isn’t essential. Strong LLVM back-end or intermediate-representation engineers who are interested in learning MLIR are encouraged to apply.

Experience with GPU, NPU, DSP, FPGA or custom-silicon compilers would be particularly relevant. Previous cryptography or Fully Homomorphic Encryption experience is useful but not required.

This is an opportunity to build a compiler around genuinely novel hardware and have significant influence over the software architecture at an early stage.
