Job Description

Machine Learning Engineer

RockstarDevelopers GmbH

• Build LLM applications. • Develop dialogue-based systems and semantic search and integrate them into the domain-specific applications of the industry solution. • Set up and maintain RAG systems, including knowledge-base management: indexing, updates, and clean source-separated storage of structured and unstructured content. • Operation and monitoring. • MLOps in production: observability, structured logging, and error analysis. • Ensure systems run reliably, not just that they worked once. • Deploy agents to production, from development and integration through to stable delivery. • Improve systems based on monitoring data, testing, and user feedback. • Identify new AI use cases, prototype them, and build data pipelines from preprocessing and model development to production.

Job Requirements

  • At least 2 years of professional experience as a Machine Learning Engineer in designing, developing, implementing, and optimizing scalable ML solutions.
  • At least 2 years of experience working in agile development teams.
  • German at least C1 level (spoken and written), demonstrable via a language certificate or as a native speaker.
  • Degree in Computer Science, Business Informatics, or a comparable qualification, verifiable by diploma or self-declaration.
  • Ideally: vector search and semantic indexing in vector databases, preferably Milvus.
  • Backend development with Python, preferably FastAPI.
  • LLM orchestration with LangChain or LangGraph.
  • Operating production-grade AI systems: monitoring (ideally Grafana), structured logging, error analysis, deployment.
  • Privacy-compliant AI design, especially when handling personal data in logging and observability.
  • Experience deploying GenAI for many users, preferably in a multi-tenant environment.
  • Kubernetes, ArgoCD, Jenkins.
  • Experience with agile delivery frameworks, ideally SAFe.
  • Experience from public sector projects.

Benefits

  • Real production projects.
  • AI that goes live with clients.
  • Not an innovation lab — no endless slide decks.
  • Remote-first within the DACH region.
  • Occasionally on-site; otherwise work from wherever you are most productive.
  • Modern AI stack.
  • RAG, agents, vector search, MLOps.
  • Current stack, no legacy baggage.
  • Internal upskilling.
  • We invest in your AI skills.
  • MacBook provided, unless the client supplies their own hardware.
  • Flat hierarchies.
  • The founders are your direct contacts.
  • A team that knows each other, even when working distributed.
