About The Company

Square One Resources connects skilled technology professionals with opportunities across the UK. We are recruiting for a high-profile public sector digital transformation programme, where experienced specialists can contribute to services operating at scale. The successful candidate will join an established technical delivery team working to develop and enhance modern digital applications in a complex, enterprise-level environment.

About The Role

We are seeking an experienced React Developer with active UK Security Check (SC) clearance to support the design, development and improvement of digital applications. This is a long-term contract opportunity, initially running until 31 March 2027, with the possibility of extension. The role is UK remote and is offered inside IR35 at a rate of £400–£500 per day.

You will bring strong hands‑on experience with React, JavaScript or TypeScript, and REST APIs. Working as part of an Agile delivery team, you will collaborate with developers, testers, product teams and other stakeholders to deliver reliable, accessible and maintainable front‑end solutions. You will contribute to technical discussions, follow established engineering standards and support continuous improvement across the team’s ways of working.

This opportunity suits a developer who is comfortable working in an enterprise‑scale environment and can balance delivery priorities with sound technical practice. Experience in government, public sector or other regulated settings is beneficial. Familiarity with Pega, Pega Constellation or React SDK would also be advantageous, but is not essential.

Qualifications

Applicants should have strong commercial experience developing applications with React and a solid command of JavaScript and/or TypeScript. You will have experience integrating front‑end applications with REST APIs, writing automated tests and building clean, scalable code. A good understanding of modern front‑end development practices and Agile delivery is expected.

You should be able to communicate clearly, collaborate effectively with multidisciplinary colleagues and contribute constructively to technical decisions. Experience with CI/CD pipelines, cloud technologies, DevOps environments or GDS and UK Government digital services is desirable. A degree or formal qualification is not specified; relevant professional experience is the key requirement.

Active UK SC Clearance is essential. Candidates must hold current, active UK SC Clearance to be considered for this position. Applications from candidates without active clearance cannot be progressed.

Responsibilities

Develop, enhance and maintain responsive digital applications using React. Build robust, readable and maintainable solutions with JavaScript and TypeScript, and integrate user‑facing features with REST APIs. Write clean, scalable code and contribute to automated testing to support quality, reliability and long‑term maintainability.

Work closely with developers, testers, product teams and wider stakeholders to understand requirements and deliver agreed outcomes. Take part in technical discussions, share knowledge and contribute to development decisions. Follow established engineering standards, delivery processes and good front‑end practices, while working effectively within an Agile, enterprise‑scale programme. Identify opportunities to improve development practices and technical solutions, and support the team in delivering secure, dependable services.

Benefits

This contract offers UK remote working, an initial term through 31 March 2027 and the potential for extension. The advertised day rate is £400–£500, subject to the contract terms, and the engagement is inside IR35. You will have the opportunity to contribute to a significant public sector digital transformation programme alongside an established technical team.

Equal Opportunity
