About The Position

Agile Defense is hiring an MSS Developer Engineer to build and maintain mission-critical analytics, applications, and decision-support tools aligned with J7 mission workflows. The role develops operator-facing dashboards and self-service capabilities, automates the delivery of insights, and ensures the accuracy and consistency of MSS deliverables. The engineer develops data pipelines, ontology, and access controls on MSS and the underlying Palantir stack; integrates external data sources into a well-modeled data foundation; and supports operationally useful AI/AIP workflows. Working with mission leaders and other teams, the role translates analytical needs into technical solutions, creates visualizations and interactive tools, and establishes alerting, monitoring, KPIs, and success metrics. The position also focuses on platform performance and scalability, including data modeling, query optimization, caching, and aggregation. It provides day-to-day operator support and escalates complex issues as appropriate. Additional duties include documenting data sources and analytical methods, contributing reusable platform content, supporting validation of the FDE&T model for potential expansion, and staying current with MSS and Palantir technologies. The role is based onsite in a SCIF in Falls Church, Virginia, and requires U.S. citizenship and an active Secret clearance at minimum; higher-level clearances may be required depending on assignment.
