Key Responsibilities
Ready to build your development career and help power a cleaner future?
Join our IT & Digital department as a Junior Full Stack Developer, working in either our Services or B2C development team to build applications that support our customers and our business.
You’ll spend most of your week building new features, working across the stack from C# backend services to Next.js and React Native applications. Our teams own what they build, so you’ll also learn to deploy and monitor your applications in Azure, seeing your work through to production.
This role is for developers early in their career. You might bring a year or two of commercial experience, or a degree, bootcamp or personal projects that show what you can do. You’ll pair regularly with experienced developers, with support from your Team Lead to help you learn, build confidence and grow.
Responsibilities:
Feature Development: Build new features across our web, mobile and backend applications, writing clean, well-tested code in C#/.NET, TypeScript, Next.js and React Native.
Cloud & Deployment: Learn to deploy, run and monitor your applications in Azure, seeing your work through to production.
Development Tooling: Use Azure DevOps for boards, repos and CI/CD pipelines.
Shaping Solutions: Work with your product manager to understand requirements and help shape practical solutions.
Quality: Collaborate with our automation tester to make quality part of everything we ship.
Teamwork & Learning: Take part in code reviews, pairing and Scrum ceremonies, learning from others and sharing your ideas.
AI & Modern Tools: Use AI tools thoughtfully to work smarter, and share what you learn with the team.
Our Teams
Our three development teams each focus on a different part of the business. You’ll join either Services or B2C, working in a small, close-knit Scrum team where we share knowledge openly and support each other to grow.
Services: The systems and integrations behind our solar installations and energy services, supporting the customer journey from sales and quoting through to onboarding and ongoing maintenance.
B2C: Our direct-to-consumer energy supply and Feed-in Tariff (FIT) platforms for households.
B2B: Energy supply and Feed-in Tariff (FIT) platforms for businesses.
Your team will include 3–4 software developers, including you, a Lead Developer and an Automation Tester. Each team works closely with a dedicated product manager, giving you plenty of opportunities to collaborate and learn.
Skills, Knowledge & Expertise
You’ll bring some experience with C#/.NET, JavaScript, TypeScript and React and/or Next.js, along with curiosity and an interest in how things work from end to end. You’ll be keen to learn, comfortable asking questions and ready to put feedback into practice.
You’ll enjoy working with others and communicating clearly, with experience of, or a genuine interest in, using AI tools in your development workflow. We use Claude, GitHub Copilot and Azure AI Foundry, but experience with other AI tools and platforms is equally welcome.
