Lead Python Backend Engineer

Quick Facts

• Role: Lead Python Backend Engineer

• Focus: Enterprise Agent Development Platform for building and scaling AI agents

• Core theme: Production agent memory, session persistence, and API integrations

Description

We are looking for a Lead Python Backend Engineer to help build an enterprise, cloud-native platform that enables teams to define, orchestrate, deploy, and observe AI agents at scale. You will standardize agent development using LangGraph and AWS AgentCore Runtime with memory capabilities across platform templates. The role emphasizes implementing memory write-on-turn and retrieve-on-turn, namespace isolation, and configuration-driven memory activation.

Responsibilities

• Integrate AWS AgentCore Memory into platform agent templates and helper libraries
• Implement write-on-turn to store session events
• Implement retrieve-on-turn 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 across the platform
• Enable memory activation through configuration rather than custom code in agent templates
• Use the 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 (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
• Skills in API integration for stateful services
• Proficiency in session management and context persistence
• English proficiency at B2 level or higher

Benefits

• Hybrid-by-design with opportunity to work remotely within Poland
• Opportunity to work abroad for up to 60 days annually
• Business-driven relocation opportunities
• Career development programs; mentoring and soft skills/well-being programs
• Certifications (Anthropic, Gemini, GCP, Azure, AWS)
• English classes
• Stable pay; Employee Stock Purchase Plan with a 15% discount
• Benefits package (health insurance, multisport, shopping vouchers)
• Referral bonuses up to $2,000
• Office perks and events; corporate, social, and well-being events
• Contractor option (B2B terms agreed individually)
