Phasecraft is the quantum algorithms company. We are building the mathematical foundations for quantum computing applications that solve real-world problems. Founded in 2019 by Toby Cubitt, Ashley Montanaro and John Morton, we are based in London and Bristol, UK. In 2023 we completed a £13m Series A funding round led by leading Silicon Valley deep tech VC, Playground Global, and in 2024 we opened our Washington DC office led by Steve Flammia.

Phasecraft’s unprecedented access to today’s best quantum computers – through partnerships with Google, IBM, Rigetti, and QuEra – provides us with unique opportunities to develop foundational IP, inform the development of next-generation quantum hardware, and accelerate commercialisation of high-value breakthroughs.

As we continue to grow and explore new areas of research, an exciting opportunity has arisen to join our talented team as a Quantum Algorithms Engineer. In this role, the ideal candidate will have experience in implementing advanced quantum algorithms or demonstrate strong potential in this area. A background in quantum computing is not necessarily required, nor is a track record of publishing scientific papers; however, the candidate should show a keen interest in quantum computing through formal or independent studies.

Job Description

1. Implement and evaluate advanced classical and/or quantum algorithms based on research conducted by our Quantum Algorithms Scientists.
2. Collaborate within a small team comprising full-time staff and affiliated PhD students.
3. Perform other activities to support the growth and success of Phasecraft.

Requirements

• Strong understanding of algorithms and their analysis.
• Bachelor's or Master's degree in Computer Science, Mathematics, Physics, or a related field.
• Ability to work independently and flexibly, producing efficient, practical code.
• Exposure to quantum computing and/or quantum information theory through formal or independent studies.
• Experience coding in quantum development environments (e.g., Cirq, Qiskit, QuEST) or implementing quantum or classical algorithms.
• Knowledge of quantum chemistry or materials science, with experience using relevant computational packages (e.g., Wannier90, PySCF), or experience with algorithms and software for combinatorial optimization (e.g., Gurobi, SAT solvers).
