About The Position

ICF Next is seeking Software Engineers (Generalists) to join a cross-functional team that operates and modernizes a mission-critical data collection and performance reporting platform for federal stakeholders. The team balances production operations with incremental modernization in a secure federal cloud environment. In this role, you will design, build, test, and support secure, accessible web applications that enable data entry, batch ingestion, validation, workflow, role-based access, reporting, and data exchange. You will contribute across the application stack, including C# and .NET services, web interfaces, APIs, SQL Server data stores, automated tests, and release pipelines. A key part of the work is strengthening the platform while it remains in active use, involving modernizing legacy components, improving performance and reliability, raising data quality, expanding automated testing and deployment practices, and making production behavior easier to observe and troubleshoot. This role is ideal for an engineer who values maintainable systems, practical collaboration, and technology that supports public health programs.
