Lead Python Backend Engineer

Quick Facts

• Role: Lead Python Backend Engineer
• Focus: Backend engineering for an enterprise AI agent development platform

Description

Lead the backend development of a production-grade, cloud-native platform that enables teams to define, orchestrate, deploy, and observe AI agents at scale. Build and integrate agent memory and session persistence features—write-on-turn, retrieve-on-turn, memory namespaces, and configuration-based activation—using Python and AWS AgentCore Memory. Standardize agent development across the organization with consistent security, quality, and governance.

Responsibilities

• Integrate AgentCore Memory into platform agent templates and helper libraries
• Implement write-on-turn functionality to store session events
• Implement retrieve-on-turn functionality to fetch relevant context
• Design memory namespace architecture for per-agent isolation and per-user scoping
• Develop Python helper libraries to support memory-enabled agents
• Enable memory activation through configuration rather than custom code in templates
• Use AWS AgentCore Memory API to create, query, update, and delete memory records
• Build and maintain API integrations for stateful services
• Manage session persistence and context continuity across agent interactions

Requirements

• 7+ years of backend engineering experience with AI/ML systems
• Hands-on production experience integrating agent memory in an agentic AI project (e.g., AWS AgentCore Memory API write-on-turn/retrieve-on-turn, memory namespace design, or agent template memory configuration)
• Expertise in Python SDK development
• API integration skills for stateful services
• Proficiency in session management and context persistence
• English proficiency at B2 level or higher
