Job Summary

Quantemol is seeking a Computational Physicist to join our quantum chemistry team, focusing on the development and application of simulation software for electron-molecule collisions. You will work primarily on Quantemol’s QEC codebase, contributing to state-of-the-art computational methods used by academic and industrial customers. The role combines scientific software development, customer-facing project work, and high-impact research in collaboration with leading academic partners. This is a full-time role. Salary negotiable based on experience.

Responsibilities

  • Develop, maintain, and extend the QEC electron-molecule collision simulation software.

  • Work with and interface to established backend quantum chemistry and scattering codes, including R-matrix-based implementations.

  • Perform electron-molecule cross section calculations for Quantemol customers across research and industrial projects.

  • Engage closely with the UK R-matrix code community to support and align ongoing development.

  • Collaborate on scientific publications with Prof. Jonathan Tennyson and the research group at University College London.

  • Apply advanced quantum chemistry and scattering theory concepts, including excited states and cross sections.

  • Contribute to consultative, customer-facing projects, translating scientific requirements into robust computational solutions.

  • Document code, methods, and results to support reproducibility and long-term maintenance.

Qualifications

Required

  • PhD in computational physics, quantum chemistry, or a closely related discipline.

  • Strong background in quantum chemistry and electron-molecule collision theory, including excited states and cross sections.

  • Excellent Python programming skills and experience working with scientific codebases.

  • Ability to work independently while collaborating effectively within a research-driven team.

  • Clear written and verbal communication skills.

Preferred

  • At least one year of relevant professional experience as a postdoctoral researcher or non-academic professional.

  • Experience working with FORTRAN codebases, particularly legacy or high-performance scientific software.

  • Familiarity with R-matrix-based electron scattering codes.

  • Experience delivering consultative or customer-facing scientific projects.

  • Experience with front-end development for scientific or engineering software.

  • Familiarity with collaborative software development practices and version control.

  • Track record of contributing to peer-reviewed scientific publications.

Quantum Jobs in the UK: Roles, Skills, Salaries and How to Get Hired (2026 Guide)

Quantum Jobs UK 2026: roles, salaries and skills across quantum computing, communications, sensing and cryptography — and how to get hired. In the UK, most quantum jobs cluster around hubs such as London, Cambridge, Oxford, Bristol and Edinburgh, with common titles including Quantum Software Engineer, Quantum Algorithm Developer, Quantum Hardware Engineer and Post‑Quantum Cryptography Specialist. The easiest way to browse live quantum jobs is via specialist boards like QuantumComputingJobs.co.uk, which curate roles specifically in this field so you are not lost in general STEM listings. This guide covers everything you need to know about quantum jobs in the UK in 2026: what roles exist, which skills are in demand, typical salary ranges, and how to position yourself to get hired.

Where to Advertise Quantum Computing Jobs in the UK (2026 Guide)

Where to advertise quantum computing jobs UK in 2026: the specialist boards, academic networks and consortia that reach quantum hardware and Qiskit talent. The global talent pool is tiny — measured in thousands, not tens of thousands — and concentrated around a small number of university physics departments, national laboratories and well-funded hardware startups. Many of the strongest candidates hold PhDs in quantum physics, quantum information or adjacent disciplines and are embedded in academic or research communities that rarely intersect with mainstream job boards. General platforms are largely ineffective for quantum hiring. Specialist boards, academic channels and direct community outreach are not optional extras — they are the primary sourcing strategy. This guide, published by QuantumComputingJobs.co.uk, covers where to advertise quantum computing roles in the UK in 2026, how the main platforms compare, what employers should expect to pay, and what the data says about hiring across different role types.

Quantum Computing Jobs UK 2026: What to Expect Over the Next 3 Years

Quantum Computing Jobs UK 2026: roles, salaries and the UK quantum hiring trends shaping hardware, software and applications careers over the next three years. Quantum computing is no longer a discipline that exists purely in academic papers and government roadmaps. It is entering a phase of genuine commercial momentum — one that is beginning to reshape the jobs market in ways that are both significant and, for well-positioned job seekers, enormously promising. The UK sits at the centre of this shift. With the government's £2 billion National Quantum Strategy committed through to 2034, a network of world-class university research groups, a growing cluster of quantum hardware and software companies, and deepening investment from major technology and defence organisations, Britain has established itself as one of a handful of countries genuinely competing at the frontier of quantum computing development and commercialisation. But the quantum computing jobs market of 2026 is a nuanced one. It is not yet the broad, deep hiring market that artificial intelligence or cloud computing represents. It is a specialist, technically demanding, and rapidly evolving landscape where the roles being created today look quite different from those that existed three years ago — and where the roles that will dominate hiring in 2028 are already beginning to take shape. The candidates who will thrive over the next three years are those who understand where the sector is heading — which technical areas are moving from research into commercial application, which adjacent skills are becoming as important as quantum physics itself, and how to position a quantum computing career that will remain valuable as the technology scales. This article breaks down what the UK quantum computing jobs market is likely to look like through to 2028 — covering the titles emerging right now, the technologies driving employer demand, the skills that will matter most, and how to position your career at the leading edge of one of the most consequential technology transitions of the coming decade.
