Principal Software Engineer, Q-CTRL

• This is a hands-on senior engineering role for someone with deep compiler expertise who enjoys solving challenging systems problems and influencing technical direction
• Strong proficiency in Python and C++
• Experience with LLVM, particularly MLIR
• Experience implementing language tooling, parsers or DSLs
• Significant experience designing production compiler systems
• Experience with compiler architectures, intermediate representations, optimisation passes and code generation
• Strong understanding of systems programming and software architecture

Desirable

• As a Senior Software Engineer on the Boulder Opal team, you will lead the design and evolution of the compiler that powers next-generation quantum computing systems. Working closely with researchers and quantum engineers, you will bridge the gap between quantum algorithms and physical hardware by building a high-performance compiler capable of translating pulse-level programs into controller instructions
• Design, implement and optimise compiler infrastructure, intermediate representations, optimisation passes and code generation
• Maintain and evolve our bespoke Python DSL used by researchers to construct pulse-level quantum programs
• Build high-performance software using Python and C++
• Work closely with researchers to translate experimental algorithms into production-quality compiler capabilities
• Run experiments on quantum hardware to validate compiler outputs end-to-end
• Influence technical direction, mentor other engineers and drive engineering best practices
• Other duties within the Employee’s skills and experience, or with reasonable training
