Machine Learning Engineer

About the role

You will build the models and pipelines behind WebbyButter's AI products: classical ML where it fits, GenAI where it wins. Expect a mix of training and evaluating models, building RAG and agent pipelines, and exposing everything through reliable APIs.

What you will do

• Train, evaluate and iterate on ML models for prediction, classification and document understanding
• Build RAG and agent pipelines using LLM APIs and open-source models
• Design datasets, labelling workflows and evaluation metrics
• Serve models and pipelines through FastAPI services with proper logging and tests
• Collaborate with full-stack engineers to integrate ML features into client applications

What we are looking for

• 1-3 years of hands-on experience with Python for ML or backend work
• Working knowledge of PyTorch or TensorFlow and scikit-learn
• Experience with at least one LLM API and with embeddings or vector search
• SQL and data wrangling with Pandas
• Comfort working in a fast-paced, collaborative team

Nice to have

• MLOps tooling (MLflow, Weights & Biases, Docker, cloud ML services)
• Vector databases such as pgvector, Qdrant or Pinecone
• Published projects, Kaggle work or open-source contributions
