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
