Quantum Compiler Engineer: OpenQASM & Circuit Optimization

Silicon-Quantum-Computing; Sydney; On-site; AUD 140,000 - 190,000; Full time

Job summary

Silicon Quantum Computing (SQC) is hiring software engineers into Compiler Services based in Sydney. You will own stages from logical circuit compilation through placement and routing, optimizing for fidelity and time budgets on real quantum hardware.

The role involves working with quantum information scientists and the QEC theory team to adapt OpenQASM, ISA changes, and control-plane integration, while turning research results into practical compiler designs.

Qualifications

• 4+ years in software engineering with production work on a compiler, solver, optimiser or comparable transformation system.
• Strong CS fundamentals: algorithms, data structures, complexity, and heuristics for hard problems.
• Graph algorithms and judicious use of approximations under constraints.
• Proficiency in Rust or C++, and Python.
• Compiler construction: IRs, passes, dataflow analysis, and rewriting.

Responsibilities

• Build and own stages of the compilation pipeline from logical circuit compilation to placement and routing.
• Implement optimisation passes to improve fidelity, depth, and runtime on real hardware.
• Target the SQC ISA and keep the compiler in step with hardware evolution.
• Collaborate with QEC theory and control-plane teams to meet hardware constraints.
• Turn research results into implementable designs and document intermediate representations.
