Job Description

Job Title: Senior Engineer - Quantum Error Correction Libraries. Location

• Santa Clara, California, USA
• Remote options available in Washington, D.C.; Washington; California; New York, New York; and Massachusetts
• Hybrid role

Responsibilities:

• Develop innovative algorithms to accelerate simulation of quantum error correction (QEC) workloads at scale.
• Research, develop, and optimize GPU-accelerated algorithms across multiple hardware generations.
• Develop, scale, and optimize software for quantum computing and quantum system simulations;
• Work closely with NVIDIA Research, Developer Technology, and Product Management teams across quantum computing, HPC technologies, and machine learning.
• Interact with external partners and researchers to understand their use cases and technical requirements.
• Provide technical leadership and mentorship to other specialists.
• Convert mathematical and research-level algorithms into robust, reusable, and well-documented software primitives.
• Apply strong debugging, functional testing, and performance testing practices;
• Contribute to high-performance software and libraries designed to accelerate quantum computing research and development.

Qualifications:

• Excellent modern C++ and Python programming skills, including debugging, functional testing, and performance testing.
• Proven ability to convert mathematical or research-level algorithms into robust, reusable, and well-documented software primitives.
• Expert understanding of QEC and stabilizer formalism, including binary symplectic representations, stabilizer and destabilizer tableaux, Pauli-frame propagation, mid-circuit measurement, and classical control;
• Strong understanding of noise models, including Pauli, correlated, and time-dependent noise, as well as exact and approximate representations of non-Pauli noise.
• Familiarity with the broader quantum software landscape, including Stim, Qiskit Aer, PennyLane, Cirq, cuQuantum SDK, CUDA-Q, or similar development frameworks.
• Strong communication skills and experience collaborating across research, engineering, and product teams.
• PhD or MS degree in Computer Science, Applied Mathematics, Physics, Electrical Engineering, or a related scientific or engineering field, or equivalent experience.
• 8+ years of relevant research or software-development experience.

Preferred:

• Proficiency in near-Clifford or stabilizer simulation techniques.
• Knowledge of QEC code varieties and procedures, including surface codes, subsystem codes, color codes, quantum LDPC, lattice surgery, and logical-state preparation.
• Hands-on experience with QEC decoders.
• Experience developing performance-critical GPU software using CUDA or a comparable environment;
• Proficiency in horizontal scaling across multiple nodes or GPUs using NCCL, MPI, NVSHMEM, or equivalent high-performance communication stacks.
• Aptitude for using agentic or AI-supported development tools while maintaining rigorous validation, testing, and code review standards.

Benefits And Compensation:

• Base salary range of $184,000 to $287,500 for Level 4.
• Base salary range of $224,000 to $356,500 for Level 5.
• Actual base salary is determined by location, experience, and compensation of employees in similar positions.
• Eligible for equity and benefits.
