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.
