About The Position

ICF Next is seeking a Software Engineer (Generalist) to join a cross-functional team that partners with federal stakeholders to operate and modernize a mission-critical data collection and performance reporting platform. This role involves designing, building, testing, and supporting secure, accessible web applications that handle data entry, batch ingestion, validation, workflow, role-based access, reporting, and data exchange. The engineer 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 aspect of the role is strengthening the platform while it remains in active use, which includes incrementally 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 position is ideal for an engineer who values maintainable systems, practical collaboration, and technology that supports public health programs.

• 2+ years working with SQL Server or another relational database, including data modeling, query development, and performance troubleshooting.
• 1+ year developing browser-based interfaces and integrating REST APIs using HTML, CSS, JavaScript or TypeScript, and JSON.
• 1+ year writing automated tests and collaborating through Git-based source control, pull requests, and code reviews.
• 1+ year implementing authentication, authorization, role-based access, and secure handling of sensitive data.
• Demonstrated ability to troubleshoot application issues, document technical solutions, and communicate effectively within a collaborative delivery team.
