• 1 year setting up and operating MCP servers
• 1 year developing and deploying bots to optimize business processes
• Technical Skills: Strong Python skills; familiarity with AI/ML frameworks (PyTorch, TensorFlow)
• MCP architecture expertise (providers/tools, resource servers, authentication/secrets)
• Hands-on experience with GenAI and agentic AI systems
• RAG implementation
• AWS operations (API Gateway, Lambda, S3, OpenSearch, CloudWatch, KMS) or equivalent experience in Azure/Google Cloud
• Robotic Process Automation (RPA) development experience
• CI/CD pipelines with containerization (Docker/Kubernetes)
• Structured logging and compliance-driven design

Nice To Haves

• MCP Server Platform (30%): Deploy, configure, and manage MCP servers (tools/providers, resource access, authentication/secrets, observability). Integrate MCP with internal services and APIs while ensuring compliance with GovCloud security standards.
• Conversational AI (10%): Build Retrieval-Augmented Generation (RAG) pipelines using GovCloud-compatible services (e.g., OpenSearch Service) for grounded responses.
• Agentic AI & Orchestration (20%): Develop agentic workflows for task decomposition, planning, tool use, and multi-agent coordination. Implement AWS Bedrock guardrails, fallback strategies, and audit trails for safe execution.
• Quality Engineering & Testability (10%): Extend modern test frameworks (e.g., Playwright) to automate UI and API testing using GenAI capabilities. Integrate MCP tools and agentic AI into test automation for dynamic test generation, intelligent validation, and adaptive error handling. Ensure structured logging, correlation IDs, and compliance-ready audit records for all test executions.
• GovCloud Architecture (20%): Map prototypes to AWS GovCloud managed services (API Gateway, Lambda, S3, OpenSearch, CloudWatch, KMS). Deliver solutions fully compatible with AWS GovCloud to maintain zero egress.
• Security & Compliance (10%): Apply least-privilege IAM, KMS-backed secrets, and token scoping for MCP tools.
