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.
