Hiring recordAdd your resume and we’ll mark which of these tools you already use, and point out anything in the posting that could rule you out.
- Demonstrated experience backtesting models against historical data and tracking experiment and backtest results systematically (MLflow or a comparable experiment-tracking tool) - Strong Python and SQL skills, including processing large time-series datasets - Experience translating a real-world operational problem (asset dispatch, resource allocation, scheduling) into a mathematical model
- Built for Growth: Rodan is building out its central data platform to support a goal of 10x revenue growth in 5 years, centered on energy market optimization across IESO, AESO, PJM, NYISO, MISO, and ERCOT. - Modern Data Stack: Work in Databricks (notebooks, MLflow and Unity Catalog Model Registry, serverless compute) with real market and meter data. - Structured Ramp-Up: In your first weeks, you'll shadow an external battery optimization build to learn the problem space, provide input, and prepare to take over the project.
- Ability to work independently in an early-stage, ambiguous environment Preferred Qualifications:- Hands-on experience with Databricks; Databricks certification is an asset - Experience with energy markets, battery storage, or demand response programs
- Backtest optimization models against historical market and meter data to validate performance before deployment - Track experiments and backtest results systematically in MLflow so model iterations are comparable over time - Partner with forecasting data scientists to integrate their forecasts as inputs to your optimization models
- 3+ years of hands-on experience building optimization models (mathematical programming, mixed-integer programming, or control-theory approaches) in a production or applied research setting - Demonstrated experience backtesting models against historical data and tracking experiment and backtest results systematically (MLflow or a comparable experiment-tracking tool) - Strong Python and SQL skills, including processing large time-series datasets

New Data Scientist postings at the employers we follow are down 3% over the last 5 weeks compared with the 5 before.
Each bar is one week of new postings. The darkest bars are the last 5 weeks.
Counted from the hiring pages we’ve followed for at least five weeks, so employers we add don’t look like growth. Updated weekly.
We file this job under Data Scientist, by the work the posting describes.
Data scientists use statistics and models to answer harder questions, such as whether a change worked, what demand will look like next quarter, or which customers are likely to leave.
Postings usually ask for Python or R, SQL, statistics, experiment design and common machine learning methods.
Unlike an ML engineer, a data scientist's main output is often an analysis or a first model, not software running inside a product.
