A major focus of this role is the modernisation of functionality from a legacy system.

This is a hands-on role with a strong emphasis on technical ownership, planning, and structured delivery. You’ll help shape how work is broken down into tickets, sequenced, and implemented, while remaining deeply involved in the build itself.

• Review pull requests, uphold coding standards, and contribute to continuous improvement of the codebase.
• Troubleshoot and resolve application issues across the stack. Participate in architectural decisions, performance optimisation, and long-term technical planning.

Requirements

• Strong commercial experience with PHP and Laravel, building and maintaining production-grade applications.
• Proven ability to understand and work with existing codebases, including legacy PHP systems, and modernise them within Laravel.
• Experience planning and delivering work: breaking down complex requirements into clear, well-scoped technical tasks.
• Strong understanding of modern Laravel patterns (Eloquent, queues, jobs, events, service layers, etc.).
