Senior Python Engineer / Phoenix

We are partnered with a fast-growing, venture-backed software startup modernizing the nuclear energy industry. The team is building mission?critical enterprise software that dramatically reduces the massive documentation and compliance burden faced by nuclear facilities. The stack is full?stack JavaScript/Python, with React on the frontend and Python (FastAPI preferred) on the backend, though experience with other modern frontend frameworks and Django or Flask is also welcome.

This is a chance to work on greenfield products that replace entire manual workflows with machine?learning-driven automation-software that directly cuts costs and improves efficiency in one of the most complex, documentation-heavy industries in the world. They're hiring mid- to senior-level engineers who thrive in startup environments, love building from scratch, and want real ownership over what they ship. You'll join a small but growing core engineering team with significant influence over architecture, product direction, and new features. The upside is real: rapid career growth, constant learning as new products are developed, and the ability to see your work have immediate, measurable impact-all while being part of a company scaling quickly and intentionally.
