• Building and maintaining features across front end and back end (web + mobile-deployed web apps)
• Refactoring and modernising an established application while adding new modules and functionality
• Designing database structures and improving performance, quality, and responsiveness
• Collaborating with stakeholders, ops / support, and other devs to deliver scalable, enterprise-ready solutions
• Reviewing code, sharing feedback, and spotting improvements with a positive, pragmatic mindset
• Troubleshooting bugs and strengthening security, accessibility, and maintainability

What you’ll bring

• 5+ years ’ commercial web / software development experience (degree optional if your track record is strong)
• Extensive hands‑on use of PHP 8+, Python 3+, MySQL 8+ (PostgreSQL also welcome)
• Solid fundamentals in HTML, CSS, JavaScript and experience with Angular 18+
• Comfort deploying and managing Unix-based servers, plus CI / CD and Git workflows
• A clear communicator who can work independently in a remote team - and talk through decisions confidently
