Summer 2027 Data Science Intern

About the role

The United States is building nuclear power again, and The Nuclear Company is writing the software that makes it possible. NOS, the Nuclear Operating System, runs the regulatory, supply chain, cost, schedule, and field work behind real reactor construction. The work matters for national security, energy independence, and the climate.

You will turn data into decisions that move a nuclear build forward. As a Data Science Intern, you do the full applied data science job on NOS: frame the question, wrangle the data, build and validate models, and put the answer in front of the people who act on it. You will work on forecasting and decision analysis for megaproject cost and schedule, extend the NOS ontology and data model, and build the analyses and dashboards leaders use to make real calls. You work next to full-time data scientists and ship work that reaches production.

This is a 12-week Summer 2027 internship (May to August), aligned to the academic calendar. Base location is Washington DC, on-site five days a week, with full housing and relocation for interns outside the DC metro area.

Responsibilities

• Frame business and engineering questions with stakeholders, then source, clean, and explore the data needed to answer them.
• Build and validate models (forecasting, classification, anomaly detection, decision analysis) for megaproject cost, schedule, and risk.
• Engineer features and extend the NOS ontology and data model across regulatory, supply chain, cost, and schedule domains.
• Build data pipelines across Palantir Foundry, AWS GovCloud, and more.
• Design metrics, dashboards, and analyses that operators, engineers, and executives use to make decisions, and communicate findings clearly.

Required Experience

• Currently pursuing a BS or MS in Data Science, Statistics, Computer Science, Applied Math, or a related quantitative field. Expected graduation between December 2027 and June 2028, and returning to school after the internship.
• Strong Python and the data stack (pandas, NumPy, scikit-learn), with working knowledge of SQL.
• Foundation in statistics and probability, and a track record of completed data analysis (course, personal, research, or prior internships).
• This position requires access to information and technology subject to U.S. export controls (including DOE 10 CFR Part 810 and NRC requirements). U.S. Person status (U.S. citizen or lawful permanent resident) is required, and TNC does not provide visa sponsorship for these roles.
• Willing and able to work on-site in Washington DC, five days a week, for the full 12-week program.

Preferred Experience

• Data visualization and dashboarding; exposure to cloud data warehouses.
• Forecasting, time-series, or experimental design.
• Coursework or project experience with Palantir Foundry or AWS.
• Interest in energy, national security, industrial software, or regulated industries.
• Familiarity with nuclear engineering concepts (not required, we teach the domain)

Benefits

• Competitive compensation packages
• 401k with company match
• Medical, dental, vision plans
• Generous vacation policy, plus holidays

Estimated Starting Salary Range

The estimated starting rate for this role is $25.00 an hour plus a $2,000 monthly housing stipend less applicable withholdings and deductions, paid on a bi-weekly basis.
