🌍 About Us

NPX partners with nuclear utilities and new reactor projects to unlock performance through innovation. We combine decades of nuclear operation expertise with AI, digital tools, and lean processes, to help plants run safer, smarter, and more cost-effectively. Our Digital Transformation team scales this expertise through both NPX-developed and industry-leading products, delivering solutions to clients across Canada, the U.S., and globally.

🧠 The Role

We’re looking for a Senior Full Stack Developer to help build the future of digital solutions at NPX. You’ll own NPX products end to end, make architecture decisions, set the technical bar for the developers around you, and play a critical role in shaping products that make nuclear safer, faster, and more cost-effective.

We’re looking for someone who has been operating at the senior level for years and is starting to think about leadership beyond a single product, the kind of work that leads to bigger roles, such as leading multiple products or growing and leading a team of developers.

Salary Range: $140-190k (Exact compensation may vary).

🎯 What You’ll Drive

Owning the technical direction of one or more NPX products, from architecture and technology choices through to production readiness

You’ll evolve them from single-client applications into platforms that scale across utilities, so every improvement reaches every plant that uses it.

Being the technical partner product managers, designers, and clients rely on to connect what’s possible, what it will cost, and what the business actually needs. When delivery calls for it, that means stepping into product decisions, leading client conversations, or picking up DevOps work yourself.

Growing NPX’s software development team through engineering standards, mentorship, and shared practices across projects.

Shaping how our team uses AI in the software development lifecycle, introducing tools and practices that make a measurable difference to speed and quality.

✨ What You Bring

Years of building and shipping production software, including several in a senior role where you owned technical outcomes, not just tickets.

Technical ownership of a product from first commit to production. You made the architecture decisions, defended the tradeoffs, and supported it post-deployment.

AI as a practical part of how you build. You use AI coding assistants and LLMs across design, coding, review, and testing, and you know where they fall short and how to check their output.

You’ve grown the team around you. You’ve driven mentorship, set standards others adopted, and helped developers take on work they couldn’t have handled before.

A habit of filling gaps across functions. When delivery needed it, you’ve stepped outside your role to keep things moving, without being asked.

Comfort turning ambiguous problems from non-technical stakeholders into delivered solutions, including being the technical voice in client conversations.

Our stack spans TypeScript/Node.js, React, Python, .NET, SQL Server/Azure SQL, Docker, Terraform, and Azure. You don’t need all of it. You should be deep in several of these and able to pick up the rest quickly.

Experience in a regulated environment, such as energy, healthcare, or finance, where quality, traceability, and security matter, is an asset.

🌿 What You’ll Find Here

To do great work, you need to be well in mind, body, and soul. At NPX, we design our environment around the whole person, not just the job they do.
