Data Engineer/100% Remote - up to 430 Euro/MD

About the Position

We are seeking a Data Engineer for a 6-month project in the energy industry, focusing on building production-grade AI applications and LLM pipelines. This role is 100% remote and based in Prague, Czech Republic.

Responsibilities

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

Requirements

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

Nice to Have

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

We Offer

• Competitive salary up to 430 Euro/month.
• 100% remote work.
• Opportunity to work on cutting-edge AI projects in the energy industry.
