• API & Integration Management: Operate and maintain critical system integrations including Weather APIs, GIS/ADMS interfaces, Apigee Gateways, and Single Sign-On (IAM) protocols.
• Network & Security Governance: Manage application certificates, TLS/PKI infrastructures, and authentication mechanisms to ensure secure communication between grid devices and the cloud.
• Grid Forecasting Coordination: Partner with engineering teams and vendors to provide technical inputs for feeder forecasting and related Demand Response programs.
• System Enhancement: Design and deploy enhancements to existing cloud-native systems to ensure long-term compatibility and interoperability with evolving grid standards.
