• Experience architecting or maintaining data lakes, data warehouses, distributed storage systems, or NoSQL solutions.
• Knowledge of platforms such as Delta Lake, Snowflake, Hadoop, or comparable technologies.
• Experience applying AI to operational decision support and the analysis of unstructured data, including text or imagery.
• Strong understanding of data security, privacy, sovereignty, and responsible AI practices.
• Experience developing dashboards, visual reports, and analytics using Tableau, Microsoft Power BI, Kibana, or comparable tools.
• Ability to translate operational problems into practical AI and machine learning solutions.
• Demonstrated success working with multidisciplinary technical teams.
• Strong written and verbal communication skills.
• Ability to explain technical concepts to non‑technical stakeholders and senior leaders.
• Ability to mentor or train personnel in AI engineering, data science, or software development concepts.

• Familiarity with NATO processes, organizational structures, operational culture, and decision‑making procedures.
• Experience supporting military, defense, government, or international organizations.
• Experience developing AI or data‑engineering solutions using open‑source frameworks and publicly available datasets.
• Familiarity with military staff workflows and operational planning processes.
• Experience with federated learning and privacy‑preserving collaboration across multiple organizations or nations.
• Experience supporting cross‑domain data sharing and API‑driven interoperability.
• Familiarity with agile project‑management methods and tools such as JIRA, Trello, or Microsoft Loop.
