Senior AI Engineer

Senior AI Engineer – AI Agents & Python - Remote - Germany - €90k

I'm working with an innovative, growing technology business building a sophisticated AI coding agent platform, and they're looking for a Senior AI Engineer to take ownership of its core architecture and development. This is an opportunity to work at the forefront of Agentic AI, LLMs and autonomous coding systems, building production-grade technology rather than experimental AI prototypes.

The Opportunity

• Design and develop AI coding agents using Python, FastAPI and asyncio.
• Build and scale agent orchestration systems, including long-running sessions, state management and recovery.
• Work with Claude Agent SDK, OpenAI Codex SDK, LangGraph and other agent frameworks.
• Develop secure sandbox environments using microVMs, Firecracker, Docker or similar technologies.
• Build robust evaluation frameworks to test agent performance, reliability and cost.
• Take genuine technical ownership of a live AI platform, influencing architecture and engineering decisions.

What We're Looking For

• Hands-on experience developing AI Agents, LLM-powered systems or agent frameworks.
• Experience with sandboxing, containers, microVMs or isolated execution environments.
• Knowledge of distributed systems, state machines, orchestration and concurrency.
• Strong software engineering fundamentals, testing and system design.
• Fluent English. German is advantageous but not essential.

Why Consider It?

• Remote working with flexibility around location.
• Work on cutting-edge AI agent technology with real-world applications.
• High level of autonomy and ownership over core engineering systems.
• Exposure to advanced LLM frameworks, agent orchestration and AI evaluation.
• Join a small, highly technical team where your engineering decisions have a direct impact.
