About the role
- •We are seeking a Principal Compiler Engineer to join Quantinuum’s quantum software team in Tokyo.
- •As a Principal Compiler Engineer, you will help design, build, and evolve the compiler and programming language infrastructure that enables quantum-classical software development.
- •You will work on novel quantum-classical programming languages, functional type systems, multi-level compiler architectures, and full-stack software systems that connect high-level developer tools to quantum and classical execution backends.
- •This role will collaborate closely with compiler teams in the UK and USA, with some international travel expected.
- •You will also work with scientific, product, and engineering teams to translate research ideas, customer needs, and platform requirements into robust, production-ready software.
- •This is a senior individual contributor role.
- •You will lead complex technical projects, mentor junior developers, set high engineering standards, and contribute to research and publications where appropriate.
- •Key Responsibilities Compiler and Language Engineering Design, implement, and evolve compiler infrastructure for quantum-classical programming workflows, including language front ends, type systems, intermediate representations, optimization passes, lowering pipelines, runtime interfaces, and backend integration.
- •Work on novel programming language features for quantum software, including functional type systems, semantic analysis, program transformation, static analysis, and correctness-oriented compiler design.
- •Develop production-quality software primarily in Python and Rust, contributing across the full stack from research prototypes to maintainable product systems.
