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
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.
Please message Harry Hansford if you’d like further information or a confidential discussion.

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
- 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
