• Familiarity with security standards and access control mechanisms (LDAP, Kerberos, RBAC)
• Experience working in Agile environments with cross-functional teams
• Experience in financial services or regulated environments is a plus

Skills

• Strong understanding of Trino architecture (coordinator/worker, execution model, query planning, resource groups)
• Expertise in performance tuning (joins, partition pruning, predicate pushdown, resource usage)
• Knowledge of modern data architectures (data lakes, lakehouses, data mesh)
• Hands-on experience with open table formats like Iceberg
• Experience in infrastructure and platform engineering (Kubernetes, Linux, networking)
