Senior Quantum Software Engineer information

What is the difference between Senior Quantum Software Engineer vs Quantum Software Developer?

AspectSenior Quantum Software EngineerQuantum Software Developer
Required CredentialsBachelor's/Master's/PhD in Computer Science, Physics, or related field; experience with quantum algorithmsBachelor's or higher in relevant field; familiarity with quantum programming languages
Work EnvironmentResearch labs, tech companies, academia; often involved in project leadershipStartups, tech firms, research teams; focused on coding and implementation
Industry UsageUsed across quantum computing, research, and development sectorsPrimarily in software development teams within quantum tech companies

The main difference is that a Senior Quantum Software Engineer typically has more experience, leadership responsibilities, and a broader understanding of quantum algorithms, while a Quantum Software Developer focuses on coding and implementing quantum programs. Both roles require strong technical skills, but the senior role often involves guiding projects and strategy.

Job description

NVIDIA's accelerated computing platform has revolutionized HPC and AI, and we have built the cuQuantum SDK to enable researchers and framework developers in the area of Quantum Computing. This role will be part of an engineering team developing, scaling, and optimizing software to accelerate and scale quantum computing and quantum system simulations. Ideal candidates will have experience building software systems and curiosity about advancing the state-of-the-art in applications of HPC and GPUs to the quantum computing ecosystem. If you are passionate about designing and developing high-performance software and want to help us build libraries to significantly accelerate research and development in this exciting field, we would love to hear from you!
What you'll be doing:
  • Researching and developing and optimizing GPU accelerated algorithms across multiple hardware generations
  • Develop innovative HPC algorithms to scale quantum circuit simulations
  • Working closely with NVIDIA Research, Developer Technology, and Product Management teams in the areas of quantum computing, HPC technologies, and machine learning
  • Interacting with external partners and researchers to understand their use cases and requirements
  • Providing technical leadership and guidance to other engineers
  • Analyzing the performance of GPU, CPU, multi-GPU/multi-node implementations, finding opportunities for algorithmic or implementation-based improvements

What we need to see:
  • Excellent C++ and Python programming and software design skills, including functional and performance test design
  • Experience programming for GPUs, in a multi-threading and multi-node MPI programming model, and expertise in hardware-aware optimization
  • Experience with agentic coding tools
  • Demonstrated ability developing scientific software used in quantum simulations (e.g., circuit simulators, compilers, hybrid-computing)
  • PhD or MSc degree in Computer Science, Applied Math, Physics, or related science or engineering field (or equivalent experience)
  • 8+ years of experience
  • Strong collaboration, communication, and documentation skills

Ways to stand out from the crowd:
  • Experience using one or more quantum computing and deep learning frameworks (e.g., Qiskit, Cirq, Pennylane, TNQVM, TensorFlow, PyTorch)
  • Proven experience with HPC technologies and communication algorithms
  • Expertise in numerical methods, Hamiltonian integrals, quantum simulation techniques
  • Experience working in an agile software development environment within a globally distributed organization

With competitive salaries and a generous benefits package, we are widely considered to be one of the technology world's most desirable employers. We have some of the most forward-thinking and hardworking people in the world working for us and, due to outstanding growth, our best-in-class engineering teams are rapidly growing.
Your base salary will be determined based on your location, experience, and the pay of employees in similar positions. The base salary range is 184,000 USD - 287,500 USD for Level 4, and 224,000 USD - 356,500 USD for Level 5.
