Principal AI Applications Engineer

US (Remote), US-Herndon-VA

We are building an enterprise ERP system from scratch where AI isn’t a feature—it’s the foundation. Join Deltek’s Engineering and Technology team to create the first truly AI‑native SMB ERP. Users will chat with their system instead of clicking through forms, intelligent agents will handle routine tasks autonomously, and you’ll use AI to write better code faster. This is a greenfield project with no legacy constraints or technical debt, giving you the opportunity to reimagine enterprise software for AI from day one.
