AI Backend Developer (m/f)

• Design, build, and maintain production-grade REST APIs in Python (FastAPI/Flask) that power AI-driven features
• Integrate and serve LLMs (OpenAI, open-source LLMs) and other NLP/ML models using frameworks such as PyTorch, Hugging Face Transformers, vLLM, llama.cpp, etc.
• Package models for deployment with Docker and automate delivery through CI/CD pipelines
• Write clean, well-tested code and participate in code reviews, and sprint planning
• Monitor, profile, and optimize APIs and model inference for performance and cost
• Collaborate with cross functional teams and contribute with ideas on architecture, MLOps best practices, and new AI capabilities
• Take ownership of your work, from concept to deployment — and refine it based on real-world feedback

• 1–3* years of hands-on Python development experience
• Solid grasp of modern web-service concepts: REST, JSON, authentication/authorization (OAuth2/JWT)
• Practical experience with at least one Python API framework (FastAPI preferred, Flask or Django acceptable)
• Basic familiarity with machine-learning libraries (PyTorch or TensorFlow) and model-serving patterns
• Basic knowledge of data handling: SQL (PostgreSQL/MySQL) and a NoSQL store (Redis, MongoDB, or similar)
• Comfortable with Git workflows and containerization (Docker); exposure to CI/CD tools (GitHub Actions, Jenkins, or GitLab CI)
• Basic cloud knowledge (AWS, Azure, or GCP)
• Eagerness to learn unfamiliar concepts quickly; whether that’s vector databases (FAISS/Milvus), prompt-engineering tricks, or new DevOps tooling
• Good written and spoken English; ability to explain complex ideas simply

We look forward to meeting you!
