Workplace: hybrid
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 in the UK and opened an office in Washington DC in 2024, led by Steve Flammia. In 2025 we completed a $34m Series B funding round co-led by Plural, existing investor Playground Global, and Novo Holdings’ Quantum Fund in its first direct quantum software investment.
Phasecraft’s unprecedented access to today’s best quantum computers – through partnerships with Google, IBM, Quantinuum and QuEra – provides us with unique opportunities to develop foundational IP, inform the development of next-generation quantum hardware, and accelerate commercialization of high-value breakthroughs.
One of the key applications of Phasecraft’s quantum algorithms is to modelling materials and molecular systems, where we have demonstrated significant reductions in cost compared with the state-of-the-art.
On the back of these breakthroughs, we are now looking to hire a Senior Quantum Computational Materials Scientist to join our team in Washington DC. In this newly created role, you will play a key role in guiding and coordinating the materials team’s research efforts in the US, working closely with the Head of the US office and the materials team lead at Phasecraft.
The ideal candidate will have extensive experience of research in the theory and application of computational techniques to materials or chemistry simulation, with an interest in applying algorithms for quantum computers to computational materials science. Their work will contribute to Phasecraft’s goal of developing quantum algorithms for near-term quantum computers, and may encompass topics such as algorithm design, optimization and implementation, resource analysis, classical and quantum simulation benchmarking. They will have the opportunity to direct and grow a portfolio of research activity across the breadth of Phasecraft’s interests.

Designs hardware-efficient quantum algorithms
Phasecraft designs quantum algorithms that reduce the hardware needed to solve hard problems, aiming to move closer to quantum advantage by lowering qubit counts and circuit depth. It tests and refines its algorithms with leading hardware partners such as Google, IBM, Rigetti, Quantinuum and QuEra to co-develop solutions for enterprise clients in fields like materials science, pharmaceuticals and telecommunications. A notable product is THRIFT, an algorithm that speeds up dynamic quantum simulations by about 10x, enabling larger and longer-running runs on near-term quantum processors. Their goal is to bridge the gap between current quantum hardware limits and future fault-tolerant machines by providing practical, hardware-efficient quantum software and intellectual property through collaborations and IP development.
