Technical ownership is central. The role shapes front-end architecture, sets and evolves engineering standards, and records key decisions using lightweight artefacts such as ADRs.

Change is delivered in a way that stays safe to ship and easy to evolve. The role sets expectations for quality across the front end, influences how work is tested and released, and reduces production risk through pragmatic controls, early validation, and a consistent, lightweight engineering discipline., * Lead and deliver features end-to-end, converting designs into production-grade code. * Set front-end architecture and coding standards, define patterns, assure quality, and drive component reuse. * Own the testing strategy across unit, integration, and end-to-end levels to keep coverage reliable and meaningful. * Optimise performance and accessibility to meet Core Web Vitals targets and WCAG 2.2 AA. * Collaborate with designers and product managers, Quality Assurance (QA), and back-end engineers to deliver small, reversible increments. * Set realistic commitments, surface risks early, and keep stakeholders aligned on scope and timelines. * Manage feature flags, canary releases, and rollback plans. * Seek and apply feedback, share domain knowledge, maintain documentation, and strengthen team learning., * Candidates must be able to demonstrate a pre-existing right to work and travel within the UK. Documentary evidence will be required. * All offers are subject to satisfactory vetting, references and occupational health checks. * Depending on the nature of the role a Disclosure Barring Service (DBS) check may also be required.
