Working Context & Environment
The organisation is one of the UK government's largest digital operators, handling millions of customer transactions annually, the vast majority of which are processed digitally. The successful candidate will be embedded in a blended squad of civil servants and supplier staff, working in a scaled agile environment. The wider approved technology stack includes Java SpringBoot for backend services, AWS Serverless (Lambda/Node.js) and legacy systems alongside Ruby on Rails and React. As initiatives span a broad portfolio of transformation-including the integration of cross government identity and payment platforms-collaboration and adaptability are essential.
