About the Role

We are looking for a collaborative and capable Next.js Developer to join a large-scale UK government agency. You will be a key contributor within a blended agile delivery squad made up of civil servants and multi-supplier staff, dedicated to building accessible, user-centred digital services. The systems you will help build are critical to the UK's infrastructure, processing over 99 million customer transactions annually and handling nearly 5 billion digital interactions.

Operating at SFIA Level 3 (aligning with the Government Digital and Data "Working" skill level), you will apply modern development standards and write clean, maintainable code with guidance and support from senior engineers. In this role, you will focus on developing Front End applications using Next.js and React, integrating them with an API-first ecosystem powered by Java Spring Boot and AWS serverless Back End technologies. You will work closely with other developers, testers, and product managers to iteratively deliver value and continuously improve the customer experience.

Key Responsibilities

• Software Development: Develop, test, and maintain responsive, user-centred web applications using Next.js, React, and modern JavaScript/TypeScript, applying established engineering standards.

• API Integration: Work with the team to successfully integrate Front End user interfaces with Back End RESTful microservices (Java Spring Boot) and AWS serverless components (such as Lambda and API Gateway).

• Quality & Automation: Write automated tests (TDD/BDD) and support the integration of your code into continuous integration and continuous deployment (CI/CD) pipelines to ensure high-quality and reliable releases.

• Accessibility & Security: Ensure that all user interfaces meet strict WCAG 2.2 accessibility guidelines and adhere to secure-by-design principles.

• Agile Delivery: Actively participate in core agile ceremonies (stand-ups, sprint planning, retrospectives) within a blended, multidisciplinary squad, collaborating with Business Analysts, Product Owners, and Agile Delivery Managers.

• Service Standards: Assist the team in gathering evidence and documenting features to ensure digital services successfully pass formal government service assessments across discovery, Alpha, private beta, and live phases.

• Continuous Learning: Troubleshoot issues, resolve technical blockers with support from senior colleagues, and continuously expand your knowledge of the strategic tech stack and public sector delivery frameworks.

Essential Skills & Experience

• Frontend Engineering: Proven commercial experience developing robust web applications using Next.js, React.js, HTML5, and CSS3.

• API Integration: Practical experience interacting with and integrating RESTful APIs and microservices within a modern web architecture.

• Inclusive Design: A strong understanding of web accessibility principles and practical experience developing interfaces that comply with WCAG 2.2 standards.

• Quality Assurance: Experience writing unit and integration tests using modern automated testing frameworks (eg, Jest, Cypress, or Playwright).

• Agile Collaboration: Experience working effectively within multidisciplinary agile teams (such as Scrum or Kanban) and using collaboration tooling like Jira and Confluence.

• Version Control & CI/CD: Proficiency with Git version control and an understanding of how Front End code integrates into CI/CD pipelines (eg, Jenkins, GitHub Actions).

Desirable Skills & Experience

• Public Sector Context: Awareness of the Government Digital and Data (GDD) Service Standard and the Technology Code of Practice.

• Cloud Platforms: Familiarity with deploying and operating Front End applications within a cloud-hosted environment, particularly AWS.

• Cross-Government Integration: Basic knowledge or awareness of strategic cross-government platforms (such as GOV.UK One Login, GOV.UK Pay, or GOV.UK Notify).

• Legacy Tech Familiarity: Exposure to Ruby on Rails, which is beneficial for understanding or migrating existing Legacy Front End applications within the agency's broader estate.
