Quantum Architect – Simulation

Job Description

Job Title: Quantum Architect – Simulation. Location: Palo Alto, California, United States

Responsibilities:

• Research and develop architectures for fault-tolerant photonic quantum computers, focusing on entanglement generation, encoded logic, and error correction.
• Develop and run large-scale simulations to evaluate performance of quantum methods and integration into full-stack architectures.
• Model generation of entangled qubit resource states using linear optical networks.
• Collaborate closely with optical architecture and fault-tolerance teams to iterate designs in response to evolving technical requirements.
• Design, develop, and maintain robust software tools and infrastructure for simulation of full-stack quantum architectures.
• Profile simulation software, optimize computational techniques, and improve performance;
• Manage simulation data, run analyses, and communicate results effectively.
• Ensure interoperability of simulation tools and modelling frameworks across projects, teams, and departments.
• Interface with software teams to hand over software tasks and propose platform and DevOps improvements.

Qualifications:

• Degree in Physics, Mathematics, Computer Science, or Electrical Engineering is required. Postgraduate degree related to quantum information or technology is preferred.
• Minimum 3 years of collaborative software engineering experience, ideally in an R&D environment.
• Strong knowledge of quantum information and linear optics.
• Familiarity with linear optical quantum computing, quantum error correction, quantum networks, error modelling, graphical calculus (e.g., ZX calculus), and tensor networks is strongly preferred.
• Extensive experience with Python; experience with a lower-level language such as C++ is preferred.
• Experience with collaborative software development tools and best practices (e.g., GitLab, CI/CD);
• Proven team player with ability to collaborate effectively across departments, sites, and time zones.
• Ability to work independently, prioritize tasks, and drive projects to completion in a fast-moving start-up environment.

Preferred:

• Hands-on experience with simulation or modelling of photonic quantum systems.
• Familiarity with full-stack quantum computing platforms.
• Knowledge of scalable software development practices in scientific computing.

Benefits and Compensation:

• U.S. Base Pay Range: $120,000 – $140,000 USD
• Bay Area Pay Range: $155,000 – $170,000 USD
• Full-time roles are eligible for equity and benefits;
• Opportunity to work on cutting-edge quantum computing research with a global impact.
• Collaborative and interdisciplinary environment with exposure to industrial-scale quantum hardware and software projects.
