Full Job Description
What you'll be doing:
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.
Ideally you'll have:
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.
Experience with FPGA development (Verilog, VHDL or HLS).
Strong understanding of systems programming and software architecture.
Bonus points (not essential, but exciting if you bring them!):
Experience with quantum control systems or pulse-level programming.
Experience with experimental characterisation of superconducting or semiconductor spin qubits.
Experience with RF signal processing concepts such as IQ modulation.
Experience using laboratory instrumentation (AWGs, digitisers, oscilloscopes, SCPI-controlled instruments).
