Crimson operates an IT staffing platform serving contract and permanent placements across the UK, built on a Microsoft-centric stack (Azure, .NET, Blazor, SQL Server). The project pipeline reveals a heavy internal transformation underway: multiple SAP implementations (S/4HANA, SuccessFactors) alongside custom SaaS CRM development and design systems work. Pain points cluster around SQL optimization, payroll automation, and large-scale HR system complexity—suggesting the engineering team is managing both client-facing platform growth and significant backend infrastructure modernization.
