Full-Stack Developer | Contingent | Washington, DC

The Full-Stack Developer will serve as a cross-functional application developer and technical support resource across the NIMS/CMIS environment. This position is designed for a versatile developer who can work across application code, databases, APIs, cloud environments, testing, deployment, troubleshooting, and production support.

The developer will work closely with the Senior ColdFusion/AWS Developer and Senior Oracle/SQL/Data Integration Developer, providing both development capacity and technical redundancy. The position will assist with application enhancements, defect resolution, SQL/database development, system integrations, testing, deployments, documentation, helpdesk escalation, and future NISC V development.

This position is particularly important to the team's continuity model: the developer will gain working knowledge across multiple NIMS/CMIS technical domains so that the team maintains secondary coverage for critical application and database functions.
