This is a hands‑on delivery role. The successful candidate will work with mission owners, data stewards, engineers, analysts, and platform teams to integrate authoritative data; improve data quality; build reusable analytics; and transition solutions into sustained operations.

• Partner with functional stakeholders to define decision problems, success measures, data requirements, and minimum viable analytic products.
• Ingest, profile, clean, transform, and integrate structured and unstructured data from authorized enterprise and legacy sources.
• Build and maintain scalable data pipelines, curated datasets, and reusable analytical data products using Python, SQL, PySpark/Spark
  , and platform‑native capabilities.
• Develop and maintain Vantage/Foundry data models, ontology‑aligned objects, transformations, workflows, dashboards, and user‑facing applications.
• Design mission‑appropriate analytical methods, including forecasting, anomaly detection, optimization, or classification when supported by data quality and operational need.
• Develop clear visualizations, dashboards, and executive‑ready readouts using Vantage/Foundry tools and as required, Power BI, Tableau, Qlik, or comparable approved tools.
• Implement data‑quality checks, lineage documentation, validation tests, model‑performance monitoring, and reproducible analytic workflows.
• Apply platform, data‑governance, cybersecurity, access‑control, and release requirements; coordinate with data owners and stewards to ensure proper use of authoritative data.
• Use Agile delivery practices: refine requirements, estimate work, demonstrate increments, document solutions, and manage technical debt.
• Train end users and analysts; create concise technical documentation, data dictionaries, user guides, and sustainment handoffs.
• Communicate findings, limitations, assumptions, and recommended actions clearly to both technical teams and senior nontechnical stakeholders.

• Demonstrated proficiency in Python and SQL for data transformation, analysis, automation, and testing.
• Experience with Apache Spark or Py Spark and distributed‑data processing concepts.
• Ability to translate ambiguous mission or business questions into implementable data and analytic requirements.
• Working knowledge of data governance, data quality, metadata, lineage, role‑based access, and responsible use of analytical models.
• Strong written and verbal communication skills, including the ability to explain analytical results and limitations to decision‑makers.
• Ability to work effectively in a cross‑functional Agile team.
• Direct experience developing in Army Vantage/Palantir Foundry
  , including data transformations, pipeline orchestration, object/ontology modeling, Workshop or application development, and operational dashboards.
• Experience supporting WDP or a DoW/Service enterprise data environment.
• Experience with machine‑learning lifecycle practices: feature engineering, validation, deployment, monitoring, drift detection, and retraining.
• Experience with cloud data services, Databricks, Delta Lake, notebooks, APIs, Git‑based version control, and CI/CD or Dev Sec Ops  practices.
