Tech Lead Engineer

We are looking for a Tech Lead Engineer to drive the design and implementation of enterprise-grade integrations based on the Model Context Protocol (MCP). This role combines Python backend engineering, protocol design, authentication, observability, and AI agent platform integration. The ideal candidate has deep experience building distributed systems, designing APIs and contracts, and leading adoption of emerging agent communication standards in enterprise environments.

What you will do

• Lead the design and implementation of MCP-based services and integrations using Python, FastAPI, and FastMCP.
• Develop and maintain MCP servers, tool adapters, and protocol-compliant integration layers.
• Design and enforce canonical API contracts, OpenAPI specifications, and schema governance standards.
• Build secure and scalable integrations with AWS AgentCore Gateway and related AI platform services.
• Implement enterprise authentication and authorization mechanisms using OAuth 2.0, JWT, and AWS SigV4.
• Design asynchronous APIs and service-to-service communication patterns for agent ecosystems.
• Establish observability standards and implement OpenTelemetry instrumentation for protocol interactions and service operations.
• Collaborate with AI platform teams to enable agent-to-tool and agent-to-agent communication capabilities.
• Define best practices for protocol versioning, backward compatibility, testing, and governance.
• Review architecture, design decisions, and implementation approaches across multiple engineering teams.
• Support enterprise security reviews, architecture review boards (ARB), and compliance processes.
• Mentor engineers and provide technical leadership for protocol adoption initiatives across the organization.
• Create technical documentation, implementation guides, and reference architectures for MCP-based solutions.

What you need for this

• Python (FastAPI, FastMCP)
• MCP protocol (Model Context Protocol specification)
• AWS AgentCore Gateway
• OpenTelemetry instrumentation
• OAuth 2.0 / SigV4 authentication
• Canonical Contract / OpenAPI schema design

Experience:

• 5+ years Python backend engineering
• Hands-on implementation of MCP servers or similar tool-protocol adapters
• REST / async API development with FastAPI or equivalent
• Enterprise authentication (OAuth, SigV4, JWT)

Will be a plus:

• AWS AgentCore Gateway early adopter or equivalent
• LangGraph or Strands agent framework experience
• Enterprise governance processes (ARB, InfoSec review)
