Senior Quantum Applications Architect at PsiQuantum (Daresbury, UK)

Job Description

PsiQuantum is hiring a Senior Quantum Applications Architect in Daresbury, UK, to lead research into quantum algorithms for fault-tolerant computers and to show, with benchmarks, where they can go beyond what classical computers can do.

At a glance

• Role: Senior Quantum Applications Architect
• Where: Daresbury, England, United Kingdom
• Pay: £78,900–92,900
• Experience: 5+ years of research in quantum algorithms and applications
• Apply: open until filled (re-checked 11 October 2026)

About the senior quantum applications role

• Propose research initiatives in quantum algorithms for fault-tolerant computers and act as a primary contributor
• Work with external partners to instantiate, validate and optimise algorithms for use cases in the life sciences, industry and elsewhere
• Establish families of benchmarks and problem instances to validate that algorithms are genuinely beyond classical reach
• Guide the simulation and analysis of resource requirements for fault-tolerant implementations on photonic hardware

PsiQuantum builds its quantum computers from photons on silicon chips. Photonic qubits are naturally suited to networking and to fusion-based quantum computing, but they need error-correction schemes and algorithms designed around photon loss and the architecture’s building blocks, which is the kind of problem these roles work on.

What PsiQuantum is looking for

• 5+ years of research experience in academia or industry in quantum computing, focused on algorithms and applications
• A degree in physics, mathematics or computer science; a PhD focused on quantum information theory or quantum algorithms is preferred
• Programming in Python, C++ or similar
• Teamwork across departments, sites and time zones, and independence in a fast-moving start-up

Nice to have

• Experience with algorithms and compilation using fault-tolerant gate sets
• Experience working with academic or industry partners on real-world quantum applications

Pay and location

PsiQuantum lists a salary range of £78,900–92,900 for this role, which is based in Daresbury, United Kingdom.
