Compiler engineer in Luton

A deep tech start-up are seeking to bolster their team with a talented frontend compiler engineer.

Responsibilities:

• Design and implement front-end compiler modules (parsers, ASTs, semantic analyzers, type systems) using or extending Clang/LLVM.
• Implement language features, ISA extensions, and front-end mechanisms to detect parallelism (loops, vectorization, task/thread-level parallelism).
• Translate high-level code into intermediate representations (LLVM IR or custom IR) optimized for Flow’s PPU-enabled backend.
• Collaborate across teams to ensure front-end output aligns with backend requirements, including instruction selection and code offloading.
• Develop diagnostics, error/warning messages, benchmarking, and tooling to improve usability, reliability, and performance of the compiler.

Requirements:

• Strong experience in compiler front-end development: parsing, ASTs, type checking, semantic analysis, IR generation.
• Proficiency with LLVM/Clang front-end and understanding of how front-end maps to back-end via IR.
• Solid understanding of CPU architectures, SIMD/MIMD, vectorization, and exposing parallelism in software.
• Familiarity with ISA extensions or custom instruction sets (e.g., RISC-V) for heterogeneous CPU + PPU targets.
• Strong software engineering skills: debugging, testing, cross-team collaboration, and delivering production-quality front-end compilers.
