AgentCore Platform Engineer
Key Skills for This Role
Full Job Posting
FOCUS AREAS
Agent Runtime & Orchestration: Build runtime patterns, memory strategies, orchestration and multi-agent handoffs, and the reference implementations other teams copy.
Gateway, Tools & Integrations: Turn internal APIs, Lambdas and legacy systems into governed tools through AgentCore Gateway, including MCP server development.
ROLE RESPONSIBILITIES
Runtime Patterns: Define how agents are structured, packaged and run on AgentCore Runtime, including sessions, state, error handling and timeouts.
Memory Strategies: Design short-term and long-term memory patterns using AgentCore Memory, and guide teams on when to use which.
Orchestration and Multi-Agent Handoffs: Build patterns for planning, tool use, supervisor/worker setups and handoffs between agents, with clear boundaries and fallbacks.
Tool Onboarding: Expose internal REST APIs, Lambda functions and legacy services as agent tools through AgentCore Gateway, using OpenAPI specs and Lambda targets.
MCP Server Development: Design and build Model Context Protocol (MCP) servers for systems that need custom integration, with clean tool definitions and schemas.
Governance and Access: Set up authentication and authorization for agents and tools (AgentCore Identity, OAuth, IAM) so agents only reach what they’re allowed to.
Legacy Integration: Work with system owners to wrap older or on-premises systems safely, handling rate limits, data mapping and error cases.
Reference Implementations and Standards: Build production-quality reference agents, starter kits and a repeatable process for adding, versioning and reviewing tools.
Evaluation and Guardrails: Build in evaluation, Bedrock Guardrails, contract tests and safety checks so agents and tools behave predictably before going live.
Enablement: Run walkthroughs, write docs and support the teams onboarding to the platform.
QUALIFICATIONS
- 5+ years of software engineering experience, with strong Python (TypeScript is a plus).
- Hands-on experience building LLM agents with at least one agent framework (e.g., Strands Agents, LangGraph, LangChain, CrewAI, OpenAI Agents SDK, LlamaIndex).
- Practical experience with LLM tool/function calling and handling model output.
- Strong AWS fundamentals: IAM, Lambda, API Gateway, containers, DynamoDB/S3, VPC connectivity and Secrets Manager.
- Experience designing and consuming REST APIs and OpenAPI specs, and auth patterns such as OAuth 2.0 and OIDC.
- Understanding of agent memory, retrieval (RAG) and context management trade-offs.
- Deep hands-on strength in at least one of the two focus areas, and working knowledge of the other.
- Clean, well-tested code that other engineers will read and reuse.
- Clear communication and comfortable teaching patterns to other teams.
PREFERRED QUALIFICATIONS
- Hands-on experience with Amazon Bedrock AgentCore (Runtime, Memory, Gateway, Identity). A strong plus, but not required.
- Experience building or running MCP servers in a real environment.
- Experience with multi-agent systems in production, including observability and failure handling.
- Experience integrating with enterprise or legacy systems, or with API management platforms (e.g., MuleSoft, Apigee, Kong).
- Experience with LLM evaluation tools and approaches.
- Experience in pharma, life sciences or another regulated industry with data access controls.
