Build and extend Relativity's agent runtime in Python, working with LangGraph, LangChain, and Deep Agents to implement capabilities like streaming, tool calling, session memory, and multi-agent orchestration. You'll need 3+ years of professional Python experience building production systems, hands-on work with LLM-powered or agentic systems, and solid understanding of async Python, API design, PostgreSQL, and cloud-native deployment with Docker and Kubernetes. This is a hybrid role based in Poland, with a salary range of 188,000–282,000 PLN.

Job Overview
WHO WE AREJob Description and Requirements
WHAT YOU’LL DO
Build and extend the agent runtime in Python using LangGraph, LangChain, and Deep Agents (deepagents) — stateful graph agents, harness profiles, and multi-agent / subagent orchestration.
Implement harness capabilities that application teams rely on — for example streaming and structured/generative output, tool calling, human-in-the-loop review, conversation branching and message queues, session memory, and checkpoint/resume (time-travel) over long-running work.
Contribute to the harness’s extensibility and protocol layer: Model Context Protocol (MCP) tool servers and clients, Agent-to-Agent (A2A) interoperability, and a registry of skills, tools, and configurations composed at runtime.
Help agents use the model that fits each use case, working across a range of LLM providers (e.g. OpenAI, Gemini).
Write clean, well-tested code and participate in design and code reviews; take ownership of components and see them through to production.
Collaborate with teammates, Applied Science, and aiR application teams to move new capabilities from experiment into production safely.
WHAT WE’RE LOOKING FOR
Required
3+ years of professional software engineering experience, with strong, recent Python building production systems.
Experience building LLM-powered or agentic systems with frameworks such as LangChain / LangGraph (or equivalent), including tool calling, orchestration, and agent state management.
Good design instincts — writing clean, testable code and contributing to the design of the components you own.
Solid understanding of modern async Python, API and service design, and relational data (PostgreSQL).
Experience delivering cloud-native systems (Azure or similar) with CI/CD and containers (Docker); familiarity with Kubernetes.
Bachelor’s degree in Computer Science, Engineering, or equivalent experience; English proficiency for technical communication.
Preferred
Experience with Deep Agents, multi-agent / subagent architectures, agent memory, or human-in-the-loop patterns.
Familiarity with the Model Context Protocol (MCP) or agent-to-agent (A2A) interoperability.
Experience with RAG and retrieval systems, citations, and evaluating LLM output quality.
Familiarity with LLM observability and tracing (MLflow, OpenTelemetry) and evals for safe model upgrades — nice to have.
Infrastructure-as-code (Pulumi/Terraform).
