Who We’re Looking For

Logical problem-solvers do well here. You’ll have completed (or be in your final year of) a postgraduate qualification (Master’s degree or higher) in a technical discipline such as Physics, Mathematics, Operations Research, Economics, Statistics, Stochastic Calculus, Computer Science, or other STEM subjects, with strong programming skills, particularly Python, C++, or Java.

You’ll be great at communicating and collaborating – driven to identify the best solution to a problem and then motivated to deliver that solution at pace.

These are qualities people at Barclays have in abundance, and we’ll help you further develop them from the day you arrive.

Barclays will accept applications from candidates who require visa sponsorship to work in the UK and will provide a skilled worker visa for successful applicants if they meet the Home Office’s eligibility criteria for a skilled worker visa. Successful applicants who are not eligible to receive a skilled worker visa, and who we are therefore unable to secure a skilled worker visa for, will be required to have their own legal right to work in the UK on a full‑time basis from their programme start date to their programme end date. The relevant start and end dates for this programme will be those confirmed to successful applicants.
