This application is slated to begin transitioning to the ServiceNow Platform in 2026 - the ideal candidate will have deep .NET experience as well as familiarity with ServiceNow Vulnerability Response and related modules.

You'll lead across the stack, from C# and SQL to Kafka, Redis, SOLR, and HBase, on a complex internal application with a mix of modern and legacy components and multiple integrations via Web APIs and Message Queues. You'll be expected to build resilient, self-healing features that gracefully handle intermittent failures. Front-end work includes maintaining and improving functionality built with ASP.NET MVC, jQuery, ES6, and Bootstrap.
