ISD is a 75+ year-old government security agency undergoing active infrastructure modernization. The tech stack reveals a hybrid environment (Windows, Linux, VMware, Intrebel, iOS/Android SDKs) typical of large government operations managing both legacy systems and mobile endpoints. Hiring velocity is accelerating with 34 open roles — 26 in security, 1 engineering — suggesting capability gaps in threat assessment and digital delivery rather than software-first transformation. Recent adoption of Model Context Protocol hints at exploration of AI-assisted intelligence analysis or code generation workflows.
