Senior Data Scientist

We need someone who can build high-quality forecasting models for UK energy balancing markets — not a generalist who's touched a bit of everything, but a specialist who genuinely understands time series, knows how to extract signal from massive feature sets, and can produce reliable probabilistic forecasts.

You'll spend significant time on tasks like: engineering features from raw market data, selecting the most predictive subset from hundreds of thousands of candidates, building gradient boosting models that output well-calibrated prediction intervals, and rigorously validating everything to avoid the subtle leakage problems that plague time series work.

You won't be responsible for deployment — we have experienced DevOps for that. But you'll need to hand off models that are well-documented, reproducible, and actually work in production. If you find satisfaction in the craft of building models that hold up under scrutiny — rather than just hitting a metric on a test set...
