    Brief

    The Home Office is seeking to re-procure development and Level 3 support services for Atlas & Immigration Caseworking, a critical 24/7 system used to manage visa and asylum applications across the UK immigration service. This procurement consolidates two existing contracts (Atlas Caseworking Asylum and Atlas Caseworking Non-Asylum) into a single engagement. The Atlas platform is a containerised open-source Java microservice application deployed on AWS that orchestrates immigration caseworking workflows using Business Process Management, delivering 2,500+ code releases annually through agile release trains. The Home Office is seeking suppliers who can demonstrate: - Expertise managing complex solutions within large agile product portfolios - Experience operating effectively in multi-supplier ecosystems - Flexibility to scale development team capacity rapidly - Strong technical skills aligned with the current technology stack - Proven experience supporting government applications with compliant onshore resources and 24/7 support capability (offshoring subject to strict security compliance) - Innovation and leadership in driving continuous improvement - Ability to leverage shared technology and resources across suppliers - Commitment to integrate with government-standard incident, service request, change and problem management tools - Capability to support frequent releases with multiple concurrent code changes This is a market engagement notice to inform procurement strategy. The contract scope, timeline, and other details may change. Participation in this preliminary engagement will not affect future procurement evaluation.
