About the Role
This is a hands-on development role focused on delivering high-quality front-end experiences alongside robust PHP-based functionality. You’ll work closely with designers and stakeholders to bring user experiences to life, while contributing to the ongoing development and optimisation of our Moodle-based platforms. We make extensive use of AI-assisted development tools and are continuing to expand this across the team, so you’ll play a part in shaping how these are used effectively.
Key Responsibilities
- Collaborate with designers to translate detailed front-end specifications into high-quality web pages, building modern, responsive interfaces that enhance user experience.
- Write clean, reusable code across both front-end and PHP components, while contributing to code reviews and supporting other developers where needed.
- Take ownership of software quality, ensuring best practices are followed across development, testing, and performance optimisation, including writing and maintaining unit and Behat tests.
System Management & Support
- Troubleshoot issues and optimise applications to ensure performance, scalability, and reliability across platforms.
- Ensure systems meet accessibility standards, GDPR requirements, and data protection best practices, while supporting QA processes and maintaining data integrity.
Collaboration & Stakeholder Management
- Work as part of a cross-functional team alongside engineers, product designers, and product managers, contributing to all stages of the agile development lifecycle.
- Engage with wider stakeholders including Learning Technologists, Sustainability Consultants, and Designers, providing technical guidance and translating requirements into effective solutions.
- Contribute to the evolution of AI-assisted development within the team, helping to identify opportunities for efficiency and quality improvements.
You must have UK work authorisation and strong English communication skills, alongside 3–5 years of commercial front-end development experience. Experience with Bootstrap, Ajax, and jQuery is important, alongside a solid understanding of writing optimised, maintainable code.
Professional Skills
You are a strong problem-solver who can optimise code and troubleshoot effectively. You communicate clearly, work well with others, and are comfortable managing multiple priorities in a collaborative environment. Experience with Moodle would be highly beneficial, along with familiarity with Docker, cloud platforms, CI/CD pipelines, and Linux environments. Knowledge of authentication protocols, WordPress, or additional programming languages would be advantageous, as would any exposure to AI-assisted coding tools or project management practices.
