Quantum Scientist

We are hiring a Quantum Algorithms Engineer to join a world-class quantum computing team pushing the boundaries of what’s possible with near-term quantum systems. In this role, you will develop and adapt quantum algorithms to solve real-world problems in collaboration with external users, research partners, and internal technical teams.

This role goes far beyond implementing pre-built tools, we're looking for someone who can contribute original thinking, deep technical insight, and a rigorous scientific approach to solving complex problems with quantum computing.

Key Responsibilities

• Design and prototype quantum algorithms tailored to real-world industrial and scientific use-cases (e.g. QML, combinatorial optimisation, quantum chemistry)
• Engage directly with end users, researchers, and technical teams to co-develop problem definitions and algorithmic approaches
• Translate abstract quantum problems into implementable solutions including hybrid models, variational algorithms, or problem-specific ansätze
• Build demonstrations and proof-of-concept solutions on hardware or simulators, working across the full quantum stack
• Contribute to internal knowledge development and play a role in shaping algorithmic strategy
  
  

Required Qualifications

• PhD in physics, computer science, mathematics, or a related discipline
• Original research or engineering experience in quantum algorithms, particularly beyond textbook or tutorial-level work
• Deep understanding of quantum algorithmic frameworks (e.g., QAOA, VQE, HHL, tensor network methods, quantum-inspired heuristics)
• Strong Python skills with the ability to prototype and iterate rapidly, comfort building beyond standard SDK abstractions
• Ability to communicate complex technical material clearly, especially in collaborative and cross-disciplinary settings
  
  

Preferred Experience

• Domain expertise in areas such as operations research, quantum machine learning, finance, chemistry, or drug discovery
• Experience in benchmarking quantum and classical approaches
• Contributions to academic research or open-source tools at the algorithm or architecture level
• Understanding of near-term hardware limitations and experience adapting algorithms accordingly
  
  

What’s Offered

• The opportunity to work at the forefront of quantum computing applications with real-world impact
• A collaborative research and engineering environment with access to cutting-edge platforms
• Hybrid work structure based in Japan, relocation support provided
• Competitive compensation, benefits, and long-term growth opportunities
