Job Technologies
Your role in the team
- We are looking for an AI Engineer / Software Developer who designs, builds, and operates production-ready AI solutions in the field of NLP and Generative AI with large language models.
- Your work includes end-to-end development from prototypes to scaling: data pipelines, prompt/model engineering (fine-tuning, RAG), evaluation, and deployment in cloud environments.
- You are proficient in programming with Python and TypeScript/JavaScript and work with PyTorch/TensorFlow, Hugging Face, LangChain/LlamaIndex, as well as vector databases (e.g., FAISS, Pinecone, pgvector).
- You develop robust services & APIs (FastAPI/Node/Express), utilize Docker/Kubernetes, CI/CD (GitHub Actions), logging/monitoring, and MLOps tools (MLflow, Weights & Biases).
- Full-Stack experience is explicitly welcome: modern frontends with React/Next.js, clean UX for AI features, as well as secure integration with backends and databases (PostgreSQL/Redis).
- You enjoy working in a team and are eager to learn every day. We do not expect perfection - curiosity, initiative, and the willingness to independently explore new topics are what matter.
- If you want to take responsibility and grow together with us, you are in the right place.
- You enjoy working closely with others and communicating clearly — in German or English. Ideally, you bring experience; however, curiosity and pragmatism are even more important to quickly iterate and drive solutions forward.
