Quantum Compiler Engineer (End-to-End)

Silicon Quantum Computing; Sydney; On-site; AUD 150,000 - 190,000; Full time

Job summary

Silicon Quantum Computing Pty Ltd in Sydney is seeking a skilled software engineer for Compiler Services. You will own the compiler stages end-to-end, from logical compilation to physical placement and routing, contributing to a scalable quantum compiler.

You will collaborate with quantum information scientists and the QEC theory team to implement optimisations and device-aware calibration inputs, while shaping the transpilation path from OpenQASM to pulse-level instructions for today’s sub-200

Qualifications

• 4+ years in software engineering with production compiler experience.
• Strong CS fundamentals: algorithms, data structures, complexity, heuristics.
• Experience with graph algorithms.
• Proficiency in a performance-oriented language (Rust or C++) and Python.
• Compiler construction: IRs, passes, dataflow analysis.
• Proven transformation correctness: equivalence checking, differential testing.

Responsibilities

• Build and own stages of the compilation pipeline from logic to physical routing.
• Implement optimization passes for real hardware: gate reduction, depth minimisation, error rate improvement.
• Target the SQC ISA and keep the compiler in step with hardware evolution.
• Handle placement and routing across wafers and chiplets under constraints.
• Implement lattice surgery, bi-layer and future error correction schemes.
• Incorporate noise models and calibration duty cycles into compilation.
