Quantum Compiler Test Engineer - 739

Quantinuum • Broomfield, CO

32d • $130,000 - $145,000

About The Position

We are seeking a Quantum Compiler Test Engineer in our Broomfield, CO location to design and execute testing strategies that validate the behavior, correctness, and performance of our quantum compiler stack. This role focuses on black-box validation of compiled quantum programs, ensuring the compiler generates correct, efficient, and hardware-compatible circuits. This role will also contribute to quantum benchmarking and validation frameworks, particularly as the system evolves toward Quantum Error Correction (QEC). If you want to work at the intersection of modern software engineering and cutting-edge quantum computing technology, please apply!

Requirements

• Bachelor’s degree in physics, Quantum Computing, Computer Science, or related field
• 5+ years of collegiate and/or industry software development experience
• 3+ years of post-graduate experience in Python, Qiskit, Cirq, pytket, Guppy, Q#, QASM, or other scientific programming language.
• Due to national security requirements imposed by the U.S. Government, candidates for this position must not be a People's Republic of China national or Russian national unless the candidate is also a U.S. citizen.

Nice To Haves

• Advanced degree (Master's/PhD) in Quantum Physics, Quantum Computing, Computer Science, or related field preferred.
• Familiarity with quantum benchmarking techniques (e.g., randomized benchmarking, cross-entropy benchmarking).
• Understanding of quantum error correction (QEC) concepts and protocols.
• Experience analyzing circuit scheduling, routing, or hardware constraints.
• Excellent communication skills, especially in explaining technical concepts to non-technical stakeholders

Responsibilities

• Design and implement black-box testing frameworks to validate quantum compiler behavior.
• Develop test plans and test scripts to detect unwanted behaviors such as invalid or inefficient qubit transportation operations, missed parallel gate execution opportunities, incorrect gate scheduling or routing.
• Validate compiled circuits against expected logical and physical constraints of the hardware architecture.
• Analyze compiled circuits for metrics such as circuit depth, parallelism, transportation overhead, resource utilization.
• Develop validation tests for QEC readiness such as logical qubit operations, and error-correction cycles.
• Identify and triage compiler misbehaviors, producing actionable reports for compiler engineers.

Benefits

• Flexible work schedule
• Employer subsidized health, dental, and vision insurance
• 401(k) match for student loan repayment benefit
• Equity, 401k retirement savings plan + 12 Paid holidays and generous vacation + sick time
• Paid parental leave
• Employee discounts
