Job Description

Overview

The nuclear sector is tackling some of the most complex challenges of our time—modernising infrastructure, enhancing safety, and accelerating the transition to low-carbon energy. Our Digital Products and Technology (DP&T) team partners with clients to address these challenges by building secure, scalable solutions that integrates IoT, robotics, and engineering data.

As a Full Stack Engineer, you’ll contribute to the design and delivery of production-grade applications across the stack—from APIs and data layers to responsive, accessible front ends—primarily on Azure. You’ll collaborate in multidisciplinary teams with engineers, consultants, and domain experts to transform complexity into elegant, maintainable solutions that drive real-world impact.

Your role

• Digital Engineering Enablement. Design, build, and evolve web-based platforms that connect engineering data, IoT devices, and robotics systems—empowering teams to make data-informed decisions and drive automation.
• Service & API Development. Deliver secure, scalable services and APIs using technologies like Node.js, .NET Core, or Python, applying clean architecture principles to ensure long-term maintainability and resilience.
• User Experience & Accessibility. Craft intuitive, performant, and accessible user interfaces using modern frameworks such as React, Vue.js, or Angular—ensuring usability across diverse user groups and devices.
• Continuous Delivery & Quality Assurance. Automate software delivery pipelines with CI/CD tools (e.g., Azure DevOps), embedding testing, quality gates, and security checks to uphold engineering excellence.
• Cloud-Native Operations. Deploy and operate solutions in cloud environments (Azure preferred), leveraging containerisation (Docker) and orchestration (Kubernetes) to enhance scalability, observability, and fault tolerance.
• Agile Collaboration & Discovery. Work within agile, cross-functional teams to co-create solutions—actively participating in discovery, backlog refinement, and iterative delivery to meet evolving user and business needs.
• Engineering for Sustainability. Champion non-functional requirements such as security, reliability, performance, and maintainability throughout the software lifecycle—ensuring solutions are robust and future-ready.

About you

• Proven experience delivering full-stack solutions that solve real-world problems.
• Strong proficiency in JavaScript/TypeScript and at least one modern front-end framework (e.g., React, Vue, Angular).
• Back-end development experience using Node.js, .NET Core, or Python, with a focus on designing robust APIs (REST/GraphQL).
• Solid understanding of both SQL and NoSQL databases, and how to use them effectively.
• Hands-on experience with CI/CD pipelines and version control using Git.
• Familiarity with cloud platforms (Azure preferred) and containerisation/orchestration tools (Docker, Kubernetes).
• A collaborative, outcome-focused mindset with strong problem-solving and communication skills.

Bonus Skills That Help You Thrive. These aren’t required, but they’ll help you make an even greater impact:

• Experience with real-time engines like Unity or Unreal.
• Exposure to deploying applications for mixed reality devices.
• Knowledge of secure coding practices and familiarity with security frameworks (e.g., OWASP ASVS, ISO 27001).
• Understanding of authentication and authorisation protocols (OAuth 2.0, OpenID Connect).
• Experience with threat modelling and vulnerability management processes.
• Familiarity with Infrastructure as Code tools (e.g., Terraform, Bicep) and DevSecOps principles.
