| Cloud Engineer | Required | Understands basic serverless concepts: AWS Lambda, Azure Functions, Google Cloud Functions. Deploys simple functions using CLI or console. Follows existing event trigger configurations and IAM policies. |
| Infrastructure Engineer | Understands serverless function basics and their role in event-driven infrastructure. Deploys pre-configured Lambda/Cloud Functions using IaC templates. Monitors function invocations and basic error logs. | |
| Platform Engineer | Required | Creates simple Lambda/Cloud Functions for automating platform tasks: webhook handlers, notifications, scheduled jobs. Configures triggers (API Gateway, CloudWatch Events). Understands cold start and execution limits. Tests functions locally via SAM/serverless. |
| Role | Required | Description |
|---|---|---|
| AI Product Engineer | Independently configures and manages Serverless Functions. Writes IaC for standard tasks. Understands networking and security basics. | |
| Cloud Engineer | Required | Independently designs and deploys serverless architectures with API Gateway, SQS, and event-driven triggers. Configures cold start mitigation, concurrency limits, and VPC connectivity. Writes Terraform/CloudFormation for serverless stacks. |
| Infrastructure Engineer | Independently configures serverless functions with proper networking, security groups, and environment management. Implements CI/CD pipelines for function deployment. Understands execution model nuances: timeouts, memory, and retry policies. | |
| Platform Engineer | Required | Develops serverless platform components: event-driven processing of infrastructure events, custom resource handlers for CloudFormation/CDK. Optimizes cold starts through provisioned concurrency. Configures observability for serverless (X-Ray, structured logging). |
| Role | Required | Description |
|---|---|---|
| AI Product Engineer | Required | Designs serverless inference pipelines for ML models using Lambda, Step Functions, and SageMaker endpoints. Optimizes cold start and memory for model serving. Implements cost-efficient auto-scaling for AI workloads. |
| Cloud Engineer | Required | Designs infrastructure solutions with Serverless Functions. Optimizes cost and performance. Introduces best practices and security hardening. |

|---|---|---|
| AI Product Engineer | Required | Defines infrastructure strategy with Serverless Functions. Establishes IaC standards. Conducts architecture reviews. Optimizes FinOps. |
| Cloud Engineer | Required | Defines serverless-first infrastructure strategy across the organization. Establishes IaC standards for function deployment, monitoring, and cost governance. Conducts architecture reviews of serverless solutions and optimizes FinOps for compute spend. |
| Infrastructure Engineer | Required | Defines platform-wide serverless strategy including standards for function design, deployment patterns, and operational runbooks. Establishes FinOps practices for serverless cost optimization. Reviews cross-team serverless architectures for reliability and security. |
| Platform Engineer | Required | Defines organizational serverless strategy: use cases vs containers, cost model, vendor lock-in analysis. Leads serverless platform creation with self-service for teams. Designs multi-region failover and disaster recovery for serverless workloads. |
| Role | Required | Description |
|---|---|---|
| AI Product Engineer | Required | Defines organizational cloud strategy. Evaluates multi-cloud vs single-cloud. Designs enterprise-grade infrastructure. Establishes FinOps practices. |
| Cloud Engineer | Required | Shapes serverless architecture strategy: Lambda/Cloud Functions for event processing, API Gateway integration, Step Functions for orchestration. Designs patterns — fan-out/fan-in, saga, circuit breaker. Defines serverless applicability boundaries and migration paths. |
| Infrastructure Engineer | Required | Defines organizational serverless infrastructure strategy: choosing between AWS Lambda, Cloud Functions, Knative for internal platforms. Designs event-driven infrastructure automation architecture through serverless functions, defines cold start optimization standards and cost boundaries for serverless workloads. |
| Platform Engineer | Required | Shapes vision for event-driven platform: serverless + event mesh + CQRS for scalable distributed systems. Defines portable serverless strategy (Knative, WASI) to avoid vendor lock-in. Evaluates WebAssembly as next-generation serverless runtime. |
