Requirements
- •5+ years in ML/DS — you have deployed models in production and understand what that means in practice
- •Proficient in Python: OOP, typing, tests
- •Classical ML: boosting, validation, understanding when a neural network is excessive and when gradient boosting is sufficient
- •Experience with text neural network models: BERT-like transformers, LLM API, prompt engineering, eval sets
- •Practical experience in MLOps: data pipelines, orchestration (Airflow, Kubeflow or similar), experiment tracking
- •Infrastructure background: Docker, CI/CD, Kubernetes, logging and monitoring — you understand how high-load services work, not just the models within them
- •Ability to think P&L: translating model metrics (F1, ROC-AUC) into conversions and money, defending technical decisions with financial arguments
- •You already have mentoring or leadership experience — and you enjoy it
