In this role, frontend is your primary discipline, and you'll broaden your contribution across the stack as your experience grows. You'll build this foundation with support from experienced teammates.

AI-assisted development is part of this role. You'll learn to use coding assistants for exploration, implementation, and debugging, while building the skills to understand their suggestions, check the results, and recognise when to ask for help.

• - Write readable code following team standards and verify your changes
• - Run existing automated tests and add basic tests for your changes with guidance
• - Learn how changes move from a pull request to a deployed application, using the team’s automated checks and deployment workflow with support
