Job summary

EPAM Systems in London, UK, is seeking a Senior AI Engineer specializing in Agentic AI to design scalable platforms that integrate LLMs, multi-agent orchestration, and RAG patterns for production-ready enterprise solutions.

You will build reusable components, orchestration engines, and governance frameworks to enable secure, scalable AI workflows. Hybrid work mode in London offers opportunities to influence platform engineering across projects.

Qualifications

• Bachelor's or Master's degree in Computer Science, Engineering or related field.
• Practical experience delivering Generative AI or Agentic AI systems into production.
• Expertise in Python engineering for APIs, microservices, testing and CI/CD workflows.
• Strong working knowledge of LLM capabilities, including prompt design, structured outputs, tool calling and retrieval strategies.
• Hands-on experience with agent orchestration frameworks (LangGraph, AutoGen, CrewAI or Semantic Kernel).
• Proven experience with RAG implementations, embeddings and vector database integrations.
• Familiarity with stateful or long-running systems, including checkpointing and resumable workflows.
• Cloud deployment experience (Azure preferred), using services such as Azure OpenAI, AI Foundry or AI Search, with Docker and Kubernetes.
• Understanding of schema validation frameworks (e.g., JSON Schema, Pydantic) and MLOps tools such as MLflow or Airflow.
• Strong communication ability to explain trade-offs around cost, latency and accuracy to technical and non-technical audiences.

Responsibilities

• Design, build and deploy Generative AI and Agentic AI solutions from prototype to production
• Implement multi-agent orchestration patterns using frameworks such as LangGraph, CrewAI, AutoGen, Semantic Kernel or OpenAI Agents SDK
• Develop the orchestration backbone for advanced workflows including planning, checkpointing, retries, fallback handling and resumption of long-running processes
• Build and optimize RAG pipelines, including chunking strategies, embeddings, vector/hybrid search and retrieval evaluation with grounded responses and citations
• Develop memory and context management solutions, including short-term and long-term stores and compaction strategies
• Write robust Python APIs and services (e.g., FastAPI), incorporating async execution, background jobs and containerized deployments
• Integrate enterprise systems and tools using protocols such as MCP, A2A, OpenAPI, REST and gRPC, ensuring graceful degradation and retries
• Apply enterprise security and governance practices including RBAC, prompt safety checks, traceability and secrets management
• Implement evaluation pipelines and observability frameworks using tools such as Langfuse, Arize or OpenTelemetry
• Contribute to architectural design decisions, code reviews and engineering standards for platform development
