Joulent | Founding ML Platform Engineer, Energy Intelligence | San Francisco | HYBRID | Full-time | equity

We deliver multi-gigawatt power to AI data centers, and this is the founding hire on the team that forecasts load and market prices. You own the whole spine: ISO/RTO market feeds, weather and plant telemetry through feature store, serving, drift detection and the model gateway.

Not a scale problem — the data is rich, not petabyte. Feeds land late and get revised after the fact without ever throwing an error, so the failure mode is a price series quietly wrong for three weeks behind a forecast that looks fine. The work is trust infrastructure: lineage, freshness SLAs, point-in-time correctness, eval gates that can block a model.

Python, SQL, Airflow, containers, IaC. 5+ years on production data and ML platforms; energy background welcome, not required.
