Job Description
Role overview
As a Senior Front-End Developer, you will help shape a high-profile UK public-sector digital service, delivering an accessible and efficient experience for end users. Working in a project-level, cross-functional Scrum team, the role focuses on building greenfield front-ends with (React, TypeScript) and collaborating across disciplines to deliver the best outcomes for customers.
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. It also involves contributing design input, leading peer reviews, mentoring colleagues, and partnering closely with product, UX, and back-end engineering teams.
Delivery centres on maintainable features, strong performance, and accessibility. The role supports WCAG AA compliance through a mix of automated checks and manual testing, and builds reusable components aligned with the Design System.
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.
Responsibilities
· 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 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.
Qualifications
Essential requirements
· 6+ years of professional front-end experience.
· Expert-level knowledge of React, including hooks, context, performance optimisation, and modern patterns.
· Solid experience with framework and its ecosystem (SSR, SSG, ISR).
· Proficient in TypeScript for scalable, type-safe codebases.
· Deep knowledge of front-end engineering practices: state management, code splitting, bundle optimisation.
· Strong testing and debugging with Playwright, Jest, Cypress, or similar.
· Proven mentoring and cross-functional collaboration delivering user-centric software.
· Strong understanding of design systems and component libraries, partnering with UX/UI.
· Track record of technical leadership guiding delivery across multi-environment projects.
· Experience shaping solutions during discovery and advising on technical feasibility.
· Experience with Git and modern branching strategies, including conflict resolution and peer PR reviews.
Desirable skills
· Cloud-native delivery on AWS or Azure, serverless or containers.
· Design System and Service Standard experience.
· Storybook ownership for UI documentation and visual review.
· Figma for collaboration and Mural for workshops.
· Front-end security basics, including XSS and CSRF protections, dependency risk scanning, and secret handling.
Security clearance and eligibility
· Active UK Security Check (SC) to start, or eligible for SC with required residency.
