AgentCore Platform Engineer

Appnovation is hiring AgentCore Platform Engineers to build the agent-facing layer of its platform. The role focuses on agent runtime, memory, orchestration, governed tools and integrations, and enabling teams to build and operate agents safely.

Responsibilities:

• Define how agents are structured, packaged and run on AgentCore Runtime, including sessions, state, error handling and timeouts
• Design short-term and long-term memory patterns using AgentCore Memory, and guide teams on when to use which
• Build patterns for planning, tool use, supervisor/worker setups and handoffs between agents, with clear boundaries and fallbacks
• Expose internal REST APIs, Lambda functions and legacy services as agent tools through AgentCore Gateway, using OpenAPI specs and Lambda targets
• Design and build Model Context Protocol (MCP) servers for systems that need custom integration, with clean tool definitions and schemas
• Set up authentication and authorization for agents and tools (AgentCore Identity, OAuth, IAM) so agents only reach what they’re allowed to
• Work with system owners to wrap older or on-premises systems safely, handling rate limits, data mapping and error cases
• Build production-quality reference agents, starter kits and a repeatable process for adding, versioning and reviewing tools
• Build in evaluation, Bedrock Guardrails, contract tests and safety checks so agents and tools behave predictably before going live
• Run walkthroughs, write docs and support the teams onboarding to the platform
