• Support platform lifecycle management by advising on upgrades, roadmap alignment, and deprecation planning.

Collaboration & Support

• Work closely with DTSS colleagues (infrastructure, cybersecurity, support, etc) to ensure cross-functional alignment.
• Provide architectural input during vendor selection and manage technical aspects of third-party solution implementation.
• Contribute to problem-solving and root cause analysis for complex application issues.
