About The Position

Agile Defense is hiring an MSS Developer Engineer to build and maintain mission-critical analytics and applications for J7 mission workflows. The role develops operator-facing dashboards, applications, decision surfaces, self-service data exploration capabilities, and automated workflows that deliver timely insights while ensuring 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 AI/AIP workflows by ensuring their data foundations are sound and their outputs useful in operations. The role works with mission leaders to translate analytical needs into technical solutions and builds visualizations, interactive tools, alerting, monitoring, and performance metrics to support data-driven decisions. The position also focuses on platform performance, operator support, reusable platform content, and organizational documentation. The engineer contributes to validation of the FDE&T model for possible extension to additional commands, stays current with MSS/Palantir technologies, and advocates for approaches that improve mission analytics. The work must be performed onsite in a SCIF. Candidates must be U.S. citizens and have, at minimum, an active Secret clearance; higher-level clearances may be required by assignment and must be obtainable and maintainable.

Requirements

Bachelor's degree in computer science, engineering, or a quantitative discipline; extensive Palantir experience may substitute.
At least 4 years of software or data engineering experience; data analysis or data science experience is also considered.
At least 1.5 years of hands-on experience with Palantir Foundry, Gotham, AIP, or MSS.
Demonstrated experience building dashboards, applications, or pipelines for operational end users.
Working proficiency in ontology design and pipeline authoring using PySpark, Code Repositories, or Pipeline Builder.
