Every candidate is assessed **solely on skills and experience against the requirements of the role** — our process is 100% competence-based and open to applicants of **all genders and backgrounds**. Tech is still far from gender-balanced, and we're actively working to change that. We'd especially love to see applications from women and non-binary people — and we welcome every qualified candidate, whoever you are.
