Maintain interface inventories, architecture diagrams, support runbooks, and recovery documentation; cross-train team members and provide technical mentoring to reduce key-person dependencies.
Partner with data and reporting teams to deliver validated source data to approved downstream platforms, preserving data lineage, quality checks, and clear system-of-record ownership.
Support vendor technical evaluations, continuity testing, and audit or examination requests by providing accurate documentation and evidence; communicate delivery progress, technical risks, and resource needs promptly to IT leadership.
