Gain is hiring an AI Engineer in Amsterdam to build LLM agents that autonomously gather and reconcile company data from across the web, alongside custom ML models for financial forecasting.

• Develop custom ML models predicting revenue, EBITDA, and buy/sell timing
• Design offline and live evaluation suites to measure agent and model performance
• Ship models and agents into production services
• Trace and debug pipeline failures end to end

• At least 3 years building both custom ML models and LLM-based pipelines or agents
• Production experience, not just demos
• Strong Python including async code
• Solid modelling fundamentals: feature engineering, validation that holds up on new data, and knowing when a model needs retraining
