About the roleThe Nuclear Company is hiring a Staff Software Engineer to lead the build of NOS modules and applications. You will report to the Director of Product Engineering and work in the Product Engineering squad. NOS is the software platform behind one of the largest nuclear buildouts in the United States, and this is a senior technical role that sets the standard for how the products get built.
This is a hands-on staff-level role. You will design and build NOS applications across desktop, mobile, and in-field surfaces, make the hard architecture calls, and raise the engineering standard for the squad. You work with platform engineers on the layers underneath and with product engineers building alongside you.
You will write production code, lead design and code reviews, mentor other engineers, and partner with business line stakeholders to turn operational needs into working software. When something is hard or stuck, you are the engineer who drives it to a decision.

- Experience leading technical design and mentoring engineers without formal authority.
- Experience with at least one major cloud (AWS preferred) and modern CI/CD.
- Excellent written and verbal communication with engineers and business stakeholders.
Preferred Experience- Experience in a regulated or safety-critical industry (nuclear, aerospace, defense, energy, medical).
- Experience with mobile (iOS/Android, React Native, Flutter), XR/VR (Unity, Unreal), or digital twin and simulation.
- Experience with IoT/OT integration, computer vision, or biometrics.
- Experience building on a platform shared by multiple product teams.
Benefits- Competitive compensation packages
