Lead Python Backend Engineer

Quick Facts

• Role: Lead Python Backend Engineer

• Focus: Backend development for an enterprise AI agent development platform

Description

Lead the backend development of a cloud-native platform that enables teams to define, orchestrate, deploy, and observe AI agents at scale. You will integrate and standardize agent memory features (write-on-turn, retrieve-on-turn, and per-agent/per-user namespacing) using AWS AgentCore Memory and develop Python helper libraries and API integrations to support stateful services and session continuity.

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 for memory-enabled agents across the platform

• Enable memory activation through configuration (not custom code) in agent 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 experience integrating agent memory in a production agentic AI project (e.g., AWS AgentCore Memory API; write-on-turn/retrieve-on-turn; memory namespace design; agent template memory configuration)

• Expertise in Python SDK development

• Skills in API integration for stateful services

• Proficiency in session management and context persistence

• English proficiency at B2 level or higher
