Theoretical Physicist – Quantum Systems (Many-Body & Open Systems)

About Us

Anyon Systems is building the next generation of superconducting quantum computers. We design and operate full-stack quantum systems, from fabrication and cryogenics to control electronics, calibration, and software. What differentiates Anyon is execution speed, technical depth, and a relentless focus on making quantum hardware work in practice, not just on paper. Our Tel Aviv R&D center is a critical powerhouse driving Anyon Systems’ global quantum roadmap. Far from a traditional satellite office, this strategic hub owns the core pillars of our technology: quantum control, calibration, benchmarking, and AI-first automation. We deliberately anchored this team in Israel to leverage the ecosystem’s unmatched pedigree in deep-tech execution, defense-grade engineering, and rigorous applied research. As a member of this team, you will operate with complete autonomy and high agency, directly shaping the flagship products deployed to our customers worldwide.

Role Overview

This role focuses on understanding complex multi-qubit dynamics, noise, and emergent behavior as systems scale, with an emphasis on models that can inform real systems.

Key Responsibilities

• Model many-body and open quantum system dynamics
• Study thermalization, crosstalk, and non-equilibrium effects
• Develop reduced models usable by AI calibration systems
• Identify scaling bottlenecks and emergent error mechanisms
• Collaborate closely with experimental teams

Qualifications

• PhD in theoretical physics or related discipline
• Expertise in many-body dynamics or open quantum systems
• Strong analytical and numerical skills

What We Offer

• A core technical role in a fast-growing quantum hardware company
• Direct access to real, state-of-the-art quantum processors
• High level of autonomy and technical ownership
• Collaboration with world-class experimental, theoretical, and AI teams across North America and Israel
• Competitive compensation aligned with senior deep-tech roles in Israel - Long-term equity participation
• Flexible work culture with strong emphasis on results, not bureaucracy - Opportunity to influence the technical direction of the company

Security / Defense Backgrounds

Candidates with backgrounds in defense, aerospace, intelligence, secure systems, RF, real-time systems, or classified R&D environments are strongly encouraged to apply. Experience operating complex systems under strict performance, reliability, and security constraints is highly valued.
