ON.energy is building the power infrastructure that makes the AI era possible.

As AI demand surges past what the grid and traditional data centers can support, ON.energy provides a new class of power technology proven at gigawatt scale and trusted by the world’s leading cloud and AI companies.

Our systems are already deployed across 2.5 GW of hyper-scale campuses, validated by top U.S. national labs, and certified for grid-safe operation by major utilities.

With real products in the field, we’re scaling faster than the grid can, transforming power from a bottleneck into a competitive advantage for the companies building the future.

As a Data Science Intern, you will support the team across the full data workflow — from understanding the problem to preparing data, running analyses, and assisting with models — while learning and applying best practices in Data Science and Machine Learning.

Understanding the Context
Understand the business problem and the technical context of each project.

Data ingestion and Structuring
Analyze and document the available data sources.





Extract information from structured files, databases, and APIs.

Organize and structure datasets for subsequent analysis.

Assist in the ingestion and acquisition of the data required for each project.

Data Quality and Cleaning
Carry out data-cleaning tasks: handling missing values, duplicates, and inconsistencies.

Validate the quality, integrity, and consistency of the information.

Identify and report data issues, as well as any relevant findings.

Analysis and Visualization
Perform exploratory data analysis to identify patterns and anomalies.

Build visualizations that make the data easier to interpret.

Help produce and, where possible, automate statistical reports to support the commercial team.

Modeling and Experimentation
Support the preparation and transformation of data for analytical and predictive models.

Take part in Machine Learning and Deep Learning experiments.
