Lead Python Backend Engineer

Quick Facts

• Role: Lead Python Backend Engineer

Description

Join the development of an Enterprise Agent Development Platform—a production-grade, cloud-native ecosystem for building AI agents at scale. The platform standardizes agent development using LangGraph and Strands Agents on AWS AgentCore Runtime, with a focus on memory, orchestration, deployment, and observability. You will integrate and operationalize AgentCore Memory, session persistence, and stateful API integrations to manage agent context reliably.

Responsibilities

• Integrate 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 (not custom code) in agent templates
• Use AWS AgentCore Memory APIs 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 production (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

Benefits

• Hybrid work model with opportunity to work remotely within Poland
• Chance to work abroad up to 60 days annually; potential business-driven relocation opportunities
• Career development programs; mentoring; thought leadership and soft-skill/well-being programs
• Certifications (Anthropic, Gemini, GCP, Azure, AWS) and English classes
• Stable pay; Employee Stock Purchase Plan with a 15% discount
• Health insurance and other benefits (multisport, shopping vouchers)
• Referral bonuses up to $2,000
• Office perks and events (entertainment/relaxation zones, snacks, coffee; corporate, social, and well-being events)
