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.

This is a six-month co-op available in the Spring 2027 (January to June), aligned to the academic calendar. Base location is Washington DC, on-site five days a week, with full housing and relocation for co-ops outside the DC metro area.

Build new features and full modules within NOS: regulatory automation, cost and schedule, supply chain, and the commercial portal.

Build AI-powered software: LLM- and agent-backed features, retrieval-augmented generation, and tool-calling against internal systems, a growing part of the platform.

Develop data integrations across Palantir Foundry, AWS GovCloud, and more.

Convert build-a-thon prototypes into production-grade features and build field deployment tooling for the teams working in the field.

Build the automated testing and compliance infrastructure that keeps NOS audit-ready; triage issues and root-cause failures.

Required Experience

Currently enrolled in a BS in Computer Science, Software Engineering, Computer Engineering, Mathematics, Physics, or a related technical field. Available for a full six-month term and returning to school afterward.

Strong programming fundamentals in at least one modern language (Python, TypeScript, Java, Go, Rust, or C++).

A track record of shipping working software (course projects, personal projects, or prior internships or co-ops).

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.
