Who We Are

Nuclearn.ai is a startup technology company delivering solutions to the nuclear and utility industries. We solve meaningful problems using advanced AI and high-quality software, deployed easily and cost-effectively. Our primary product is a web platform that tightly integrates workflow automations, machine learning model deployment, dataset management, and analysis to address specific challenges for our customers in both the nuclear and broader utility sectors. The Nuclearn.ai platform is currently in use at over 50 nuclear reactors across North America, and we are actively expanding our reach to every nuclear utility in the U.S. and abroad, as well as other utility sectors.

Position Overview

At Nuclearn, we are seeking a Quality Assurance (QA) Engineer to ensure the reliability, performance, and usability of our rapidly evolving AI platform. In this role, you'll work closely with our engineering, product, and customer success teams to build robust testing frameworks, catch bugs before they hit production, and uphold a high standard of software quality for our customers in the nuclear and utility sectors.

If you're passionate about quality, love breaking things (so they don't break later), and are excited to grow alongside a fast-paced startup using automation and AI to enhance software quality, we want to hear from you.

Eligibility :

U.S. citizenship or permanent residency (green card holder) is required due to DOE Export Compliance.

What You'll Be Doing

• Design, write, and execute automated and manual test cases across our React frontend and Python backend.
• Build and maintain test automation frameworks (e.g., Cypress, PyTest) to validate platform functionality, API integrations, and user workflows.
• Proactively identify areas to apply automation and reduce manual test burden, especially in regression and smoke testing.
• Explore and apply AI-assisted approaches to test generation, bug prediction, and defect triage as part of continuous improvement.
• Own end-to-end regression testing for product releases and critical customer workflows.
• Identify, document, and track software bugs and inconsistencies, driving resolution before production deployment.
• Establish and evolve QA processes, promoting a culture of quality throughout the development lifecycle.
• Work closely with DevOps to ensure quality in CI / CD pipelines and automated deployments.
