About the role

We are looking for a Senior Platform Engineer (Agent Gateway) to design and operate secure, scalable agent communication infrastructure built on AWS AgentCore Gateway. The role focuses on A2A protocol implementation, agent discovery and routing, gateway architecture, authentication, and multi-agent platform integration. The ideal candidate combines strong Python backend engineering skills with deep expertise in distributed systems, API gateways, and AI agent ecosystems.

Our customer is a multinational corporation with more than a century of history and offices in over 180 countries. Their most ambitious goal at the time is to introduce a range of Reduced-Risk Products (RRPs). The target audience is more than 1 billion consumers around the globe. IT platform hosts 700+ applications.
Intellia’s mission is to help the client with the engineering of a comprehensive software ecosystem for a game-changing IoT product on the margin of innovative consumer experience and cutting-edge technology. Our teams are involved in the engineering of core platform components for best-in-class eCommerce, Digital Marketing and IoT solutions. As an Engineer, you will become a part of Core Architecture Team and be responsible for the architecture, implementation of best practices in our Digital Engineering Enterprise Platform.
The Platform is a set of services and internet applications that accelerate the development and delivery of software applications by taking care of common SDLC challenges. The Platform provides access and consumption for engineering teams to a set of services, technologies, practices for their development and for operating their application, ensuring a set of compliance and best practices.

What you'll do

Design and implement agent communication platforms using AWS AgentCore Gateway.
Build backend services and integrations using Python and AgentCore SDK.
Develop agent discovery, registration, routing, and invocation workflows following A2A protocol specifications.
Design and enforce secure trust models for agent-to-agent communication.
Implement OAuth 2.0 and SigV4 authentication and authorization mechanisms for A2A channels.
Design gateway deployment topologies, including shared and tenant-isolated architectures.
Establish routing, governance, and policy enforcement mechanisms across agent ecosystems.
Integrate AI agent frameworks such as LangGraph and CrewAI into enterprise agent platforms.
Design scalable multi-agent orchestration and communication patterns across distributed environments.
Perform gateway performance testing, load validation, capacity planning, and latency analysis.
Conduct security testing and threat assessments for agent communication channels.
Collaborate with security, platform, and AI engineering teams to establish operational standards and best practices.
Create technical documentation, architecture guidelines, and platform implementation standards.
Support production operations, troubleshooting, and continuous optimization of gateway infrastructure.
The possibility of being a Team Leader.

Nice to have

• AWS AgentCore Gateway A2A enforcement model hands-on

• AWS AgentCore Runtime multi-agent invocation patterns

• Enterprise A2A governance standard authoring

• LangGraph or CrewAI multi-agent orchestration experience

Skills

• AWS AgentCore Gateway (A2A protocol — agent card registration, routing, enforcement)

• Python backend engineering (AgentCore SDK)

• A2A protocol specification (agent discovery, invocation lifecycle, trust model)

• OAuth 2.0 / SigV4 authentication for A2A channels

• AgentCore Gateway deployment topology design (single vs. per-tenant)

• Performance and security testing for gateway workloads

Experience

• 5+ years platform or backend engineering

• Hands-on production experience with an agent-to-agent or agent-to-tool gateway platform (AWS AgentCore Gateway, or a comparable agent/tool routing and discovery layer — e.g., MCP gateway implementations, agent mesh/proxy products)

• OAuth 2.0 and identity-based routing for machine-to-machine or agent-to-agent traffic

• Production implementation work on at least one multi-agent system (not just framework familiarity — built or operated agent-to-agent communication)
