Principal AI Engineer

  • Practice Development & Integration

  • Technologies Artificial Intelligence

  • Location Bremen, Germany

  • Salary NON 125,000

  • Type Permanent

AI Engineer - Agent Systems - Berlin OR Remote | €110k

 

This is not a typical AI Engineer position. You'll be part of an AI-native systems team building agent-based applications in production - designing and deploying AI agents that operate in real-world environments, not just prototypes. LLMs are not a feature here — they are the core runtime.

 

You’ll work on systems where agents plan, reason, use tools, and deliver outcomes end-to-end.

We’re looking for engineers who don’t just understand AI — but can turn it into working products.

 

What you’ll do

  • Build and deploy AI agents in production (not demos)
  • Design RAG systems (retrieval, memory, context management)
  • Create LLM orchestration pipelines and multi-step workflows
  • Develop tool-using agents (APIs, functions, external systems)
  • Work directly with clients to turn problems into working solutions
  • Influence product direction and experiment with new agent capabilities
  • Own systems end-to-end: from idea → build → deploy → iterate

 

What we’re looking for

  • Strong software engineering background (4+ years or equivalent)
  • Hands-on experience building with LLMs in real applications
  • Experience with: RAG systems, Agent frameworks / orchestration, APIs and backend systems (Python preferred)
  • Ability to build and ship independently

Nice to have

  • Experience with tools like LangChain, LlamaIndex, or similar
  • Experience with vector databases and retrieval systems
  • Full-stack capability (you can ship end-to-end)
  • Background as a founder, early/founding engineer

 

What makes you stand out

  • You’ve built something real: A product, startup, or widely used tool
  • You have public proof of work: GitHub, side projects, demos, or benchmarks
  • You think in products and use cases, not just models
  • You’re comfortable working directly with users or clients

 

Why join

  • Work on real AI systems, not slideware
  • Build and deploy agents that actually get used
  • High ownership, low hierarchy
  • No line management — this is a pure builder role
  • Fast iteration, real-world deployment
  • Small team of highly autonomous engineers
  • Shape the direction of an emerging agent-first platform
  • Flexible setup with Berlin base or full remote option
