Quantum Compiler Engineer

SQC Silicon Quatum Computing; Sydney; On-site; AUD 180,000 - 240,000; Full time

Job summary

SQC Silicon Quatum Computing, based in Sydney, is hiring software engineers for the compiler services team. You will own stages from logical circuit compilation to physical placement, focusing on fidelity and time budgets rather than gate count.

The role involves working with quantum information scientists and QEC researchers to shape the compiler for real hardware. You will contribute to lattice surgery, bi-layer schemes, and error-correction workflows, while translating research papers into

Qualifications

• 4+ years in software engineering with production compiler experience.
• Strong CS fundamentals: algorithms, data structures, complexity and heuristics.
• Experience with graph algorithms and approximations under constraints.
• Proficiency in Rust, C++, and Python; compiler construction experience.
• Proving a transformation correct: equivalence checking and differential testing.
• Experience with Git workflows, code review, CI and testing.

Responsibilities

• Build and own stages of the compilation pipeline, from logical circuit compilation through to physical placement and routing.
• Implement optimisation passes that reduce gates, depth and error rates on real hardware.
• Align compilation with the SQC ISA and evolving control plane.
• Solve placement and routing across wafers and chiplets under connectivity constraints.
• Implement lattice surgery, bi-layer and future error correction schemes with the QEC team.
• Incorporate noise models and calibration duty cycles into compilation for target devices.
• Develop the transpiler path from OpenQASM to pulse-level instructions for sub-200 qubit devices.
• Verify correctness of transformations via equivalence checking and differential testing.
• Benchmark compiler output across fidelity, depth, and runtime metrics.
