AI Engineer / Data Engineer

For our client in the energy industry, we are currently looking for an AI Engineer / Data Engineer
EU only !!!

Project & Role Overview
The role focuses on building production-grade AI applications and LLM pipelines, with a strong emphasis on scalability, observability, and modern development practices.

Key Responsibilities

• Develop production-grade Python applications using FastAPI, including async patterns and clean/easy patterns
• Build and manage LLM pipelines using OpenAI SDK, LangChain, or LangGraph
• Apply prompt engineering techniques, including structured outputs and Human-in-the-Loop (HITL) design
• Ensure LLM observability, meaning continuous monitoring, understanding, and analysis of LLM behavior in production (e.g., GPT, Copilot)
• Work with REST APIs and event-driven architectures
• Handle PostgreSQL databases and manage upstream/downstream data contracts
• Use AI coding tools such as GitHub Copilot, Codex, Claude Code, or similar
• Implement CI/CD pipelines, Docker-based environments, and follow testing best practices (testing pyramid)

Must-Have !!!

• Strong Python expertise with production-grade development (FastAPI, async patterns)
• Experience with LLM pipelines (OpenAI SDK, LangChain, LangGraph or similar)
• Solid prompt engineering skills (structured outputs, HITL concepts)
• Understanding of LLM observability (monitoring and analyzing LLMs in production environments)
• Experience with CI/CD pipelines, Docker, and testing strategies (testing pyramid)
• Experience with REST APIs and/or event-driven APIs
• Database experience, especially PostgreSQL
• Familiarity with AI coding tools (GitHub Copilot, Codex, Claude Code, etc.)
• Knowledge of data contracts (upstream/downstream integration)
• English fluency (mandatory)

Nice-to-Have Skills

• Experience with event-driven architecture (Azure Service Bus, Kafka, RabbitMQ or equivalent)
• Knowledge of async workers, fan-out / join patterns
• Experience with Azure-native services (Container Apps, KEDA autoscaling, IAM, secrets management)
• General Azure experience
