Software Engineer, Quantum Architecture (Remote, US or Canada)

We are seeking an expereinced Software Engineer for a leading Quantum Computing company. This team is responsible for building the core software and data systems that underpin the study and simulation of quantum computer architectures.

This role defines and evolves the architectural foundations of the quantum R&D stack - spanning high-performance computing, data platforms, and scientific workflow integration. This team builds and supports the internal software platforms that enable these efforts - developing and maintaining simulation frameworks, data systems, and computational tools used to evaluate and explore architectural concepts.

You ll work directly with physicists, software engineers, and researchers to turn computational ideas into sustainable, high-value software systems that drive the simulation and exploration of quantum architectures.

This is a 6 month project (extensions or conversion to FTE possible), 40 hours per week, Remote in the US or Canada.

This is a w2 role in the US as a Stage 4 Solutions employee, with Healthcare benefits and 401K offered.

Responsibilities :

• Design, develop, and maintain core software infrastructure used across quantum architecture, linear optics, and fault-tolerance R&D teams.
• Build and evolve data pipelines and platform components to support high-performance simulations and experimental workflows.
• Collaborate closely with researchers and computational scientists to translate experimental and modeling requirements into robust, usable software systems.
• Develop efficient Python modules and C++ bindings, ensuring high performance and seamless integration between computational layers.
• Design, implement, and maintain performant C++ components and interfaces that underpin core simulation and computation workflows, ensuring robust integration with Python-based systems
• Improve existing codebases through refactoring, testing, and modernization - balancing innovation with stability and long-term maintainability.
• Contribute to CI / CD workflows and deployment systems, ensuring reliability and reproducibility of R&D software environments.
• Model complex scientific domains in software through well-structured, typed, and testable components.
• Participate in cross-functional reviews to drive best practices in testing, versioning, and reproducibility for scientific workloads.
