Responsibilities

• Contribute to the technical migration of existing Golang and Java-based routing services to a next-generation Kubernetes-native API gateway platform, ensuring zero-downtime transitions
• Design, develop, and maintain cloud-native routing configurations, policies, and automation tooling including rate limiting, request/response transformation, and traffic shaping
• Implement modern authentication and authorization patterns including JWT, workload identity, and claims-based routing to enable secure service-to-service communication
• Develop and maintain observability tooling, dashboards, and alerting to ensure platform health
• Partner with cross-functional teams to validate routing requirements and ensure business continuity
