• Release, Maintenance & Governance.
• Deployment & Change Management: Prepare technical design specifications and migrate update sets/scoped applications across sub‑production and production instances.
• Upgrades & Testing: Lead unit testing, resolve defects, support platform upgrades, patching, and automated test framework (ATF) validations.
• Emerging Platform Capabilities: Explore and integrate ServiceNow AI innovations (e.g., Now Assist and AI agents) to optimize asset operations and user self‑service.
• Stakeholder Collaboration & Enablement.
• Requirements Translation: Partner closely with IT Asset Managers, Procurement, and ITIL process owners to translate business licensing rules into technical platform specifications.
• Knowledge Transfer: Author technical architecture documents, administrative runbooks, and user‑facing knowledge bases; mentor and onboard fellow team members.
