• Strong commercial experience with Python, including building and maintaining production-grade applications.Hands-on experience with FastAPI.
• Practical experience with at least one AI agent framework and building solutions based on LLMs.
• Good understanding of agent orchestration, context and state management, and multi-step workflows.
• Experience designing tool schemas, tool-calling mechanisms, and integrations with APIs and other systems.
• Very good knowledge of REST APIs, including response streaming.Hands-on experience with Google Cloud Platform (GCP).
• Experience designing production-ready solutions with scalability, reliability, security, and observability in mind.
• Strong understanding of clean code principles, testing practices, code reviews, and software engineering standards.
• Ability to make independent technical and architectural decisions and clearly communicate the reasoning behind them.
• Fluent in Polish.

Responsibilities

• Design and develop AI agent orchestration architecture, including multi-step workflows, state and context management, error handling, and retry mechanisms.

• Deploy and maintain solutions on Google Cloud Platform (GCP), including deployment, scaling, monitoring, and cost optimization.
• Ensure reliability and observability of agent-based systems through logging, monitoring, and tracing of LLM and tool calls.
• Implement mechanisms for evaluating response quality and introducing appropriate safeguards, including guardrails and tool access control.
• Optimize solution performance and costs, particularly in terms of latency, token consumption, and model selection for specific tasks.
• Define and maintain engineering and coding standards within the team, including code reviews, testing practices, development conventions, and technical documentation.
• Collaborate with product and business teams to translate business requirements into effective AI agent solutions.
• Keep up with developments in the AI agent ecosystem, including MCP and multi-agent architectures, and recommend technologies and approaches suitable for production use.

Our offer
