• Develop custom REST/SOAP web services, Scripted REST APIs, webhook handlers, and Integration Hub spokes.
• Ensure secure communication channels (OAuth 2.0, mutual TLS) and implement resilient error-handling, payload validation, and retry mechanisms.

4. Testing, Quality Assurance & Deployment

• Define and execute unit, functional, integration, and user acceptance testing (UAT) across development, sub-production, and production environments.
• Build and maintain automated test suites using the Automated Test Framework (ATF) to reduce regression cycles during migrations and family upgrades.
• Oversee update set governance, CI/CD deployment pipelines, code review routines, and production release management.

5. Collaboration & Platform Leadership

• Partner closely with the Head of ServiceNow Platform, platform administrators, product owners, and business stakeholders to align sprint deliverables with strategic roadmaps.
• Document technical architecture specifications, data schemas, interface agreements, and standard operating procedures (SOPs).
• Mentor junior developers and system administrators on clean code practices and ServiceNow architectural standards.
