Senior Cloud Engineer

• Design and implement serverless workloads on AWS using Lambda, API Gateway, EventBridge, SQS, SNS, Step Functions, DynamoDB, and S3.
• Author and maintain CloudFormation (YAML) templates as the source of truth for infrastructure, including nested stacks, change sets, and drift detection.
• Build and maintain CI/CD pipelines that lint, test, package, and deploy CloudFormation stacks and code across environments with defined promotion and rollback strategies.
• Develop Python based Lambda functions, internal tooling, and automation with appropriate testing, logging, error handling, and dependency management.
• Provide architecture guidance for distributed event-driven systems, including choreography vs. orchestration, idempotency, delivery semantics, dead-letter and replay strategies, and schema evolution.
• Define event contracts and async integration patterns in partnership with application teams.
• Implement observability across services: structured logging, distributed tracing (OpenTelemetry), metrics, and actionable alarms.
• Participate in incident response and post-incident reviews and convert findings into automated guardrails and runbooks.
• Conduct code and design reviews; mentor junior and mid-level engineers on serverless patterns, IaC standards, and operational practices.
