We are seeking a Senior Applications Support Developer to provide advanced production support for business-critical applications, integrations, and related services. This role requires strong technical troubleshooting skills, application support experience, analytical thinking, and the ability to independently diagnose and resolve complex production issues.

This person will support both legacy Java applications and modern .NET-based applications and integrations. The role will initially require hands-on support and troubleshooting of the existing Java application while also supporting the organization’s .NET integrations. As the legacy application is migrated to a modern .NET platform, this person will support the transition and then provide production support for the modernized application.

The ideal candidate has strong experience supporting enterprise applications; working knowledge of .NET/C#; the aptitude to navigate an unfamiliar legacy Java codebase for production troubleshooting; strong SQL troubleshooting skills; experience analyzing application logs and API responses; release/deployment support experience; and clear communication with technical and non-technical stakeholders.
