Role	Required	Description
Infrastructure Engineer		Understands Envoy listener/cluster/route architecture and xDS API basics. Uses existing configurations to route traffic between services. Debugs connectivity issues using Envoy admin interface and access logs.
Platform Engineer	Required	Understands Envoy sidecar model and service mesh data plane concepts. Applies existing filter chains and route configurations for service-to-service communication. Monitors proxy metrics and health check endpoints under guidance.

Role	Required	Description
Infrastructure Engineer		Independently configures and manages Envoy Proxy. Writes IaC for common tasks. Understands networking and security basics.
Platform Engineer	Required	Independently configures and manages Envoy Proxy. Writes IaC for typical tasks. Understands networking and security basics.

Role	Required	Description
Infrastructure Engineer	Required	Designs Envoy fleet configurations with advanced load balancing (ring hash, Maglev) and circuit breaking. Implements rate limiting with external gRPC services and custom Lua/Wasm filters. Hardens mTLS settings with SDS integration and certificate rotation.
Platform Engineer	Required	Designs Envoy-based API gateway layer with JWT validation, RBAC filters, and per-route rate limits. Optimizes connection pooling and upstream health check tuning for low-latency microservices. Implements Wasm extensions for custom observability and traffic shaping policies.

Role	Required	Description
Infrastructure Engineer	Required	Defines infrastructure strategy with Envoy Proxy. Establishes IaC standards. Conducts architecture review. Optimizes FinOps.
Platform Engineer	Required	Defines infrastructure strategy with Envoy Proxy. Establishes IaC standards. Conducts architecture reviews. Optimizes FinOps.

Role	Required	Description
Infrastructure Engineer	Required	Defines Envoy strategy as universal data plane for the organization: sidecar and gateway deployment architecture, xDS control plane integration, custom WASM filter development. Designs observability standards through Envoy access logs and tracing, makes decisions on Envoy vs nginx vs HAProxy.
Platform Engineer	Required	Defines service mesh and API gateway strategy based on Envoy for the platform: xDS API, custom filters (Lua/WASM), rate limiting. Designs traffic management architecture for multi-cluster. Evaluates Envoy Gateway as ingress controller replacement for unifying the platform data plane.
