About The Role

The Nuclear Company is hiring an AI Engineer 1 to build test automation and quality practices for NOS, the Nuclear Operating System, that meet NQA-1 nuclear quality assurance standards. NOS is the software platform behind one of the largest nuclear buildouts in the United States, and every module it ships must meet the rigor that nuclear regulation demands. This role sits at the intersection of software quality, regulatory compliance, and AI-augmented engineering.

This is a hands-on, entry-level role with a clear differentiator: you will use AI as a tool to generate, review, and improve tests, while also developing the skills to test AI-powered systems themselves.

Requirements

and Palantir Foundry, and help establish the verification and validation (V&V) practices that give NOS its regulatory backbone.

into traceable test artifacts and evidence packages. Establish and refine defect tracking and V&V workflows alongside the Compliance/Quality/Testing Lead, ensuring traceability from requirement to test to resolution. Ramp on Palantir Foundry, the NOS architecture, and the team's AI tooling, understanding how data flows through the system and where quality gates apply.

Contribute to the team's approach for testing AI-powered features within NOS, prompt regression, output validation, and behavioral consistency checks. Required Experience Computer science degree or equivalent, with 0-2 years of professional experience (internships, co-ops, and project work count). Test automation fundamentals in at least one modern framework: Playwright, Cypress, Jest, PyTest, or equivalent.

Has used AI to generate, review, or improve tests in a real project, not just theoretical knowledge, but hands-on application. Strong fundamentals in at least one backend language (Python or TypeScript preferred). Good written and verbal communication, and willingness to learn the nuclear regulatory environment (NQA-1).

Responsibilities

Build automated test coverage (unit, integration, and end-to-end) for assigned NOS modules, using AI-assisted generation and review to accelerate coverage and catch gaps.
