Senior PHP Developer - Laravel - Remote UK


High-growth health-tech business currently undergoing a technical evolution backed by recent private equity investment - transitioning from an underinvested custom PHP framework to a modern, scalable Laravel architecture.


Not just a website; it’s a complex ecosystem that manages everything from approvals and prescriptions to warehouse management and global shipping.


We are looking for a Senior PHP Developer to join a small team and lead the charge in untangling a 15-year-old codebase into a high-performance platform.


The Challenge

  • Refactor a legacy, non-OOP PHP 8.3 platform into a modern MVC architecture (Laravel/Hotwire).
  • Manage intricate back-office processes and a web of external integrations and APIs.
  • Build a resilient system where changes no longer cause regressions, reducing stress for the core team and enabling organic growth.


What You’ll Do

  • Architectural Leadership: Lead the migration from a legacy custom build to Laravel, shaping the future of our technical standards.
  • Full-Stack Ownership: Own features end-to-end, from MySQL optimisation to managing AWS infrastructure and deployments.
  • AI-Enabled Development: Leverage tools like Claude and LLMs to accelerate development and stay at the forefront of "AI-enabled" engineering.
  • Collaborative Building: Work directly with the CTO and a UI/UX designer in a high-trust, low-ego environment.


What We’re Looking For

  • Integration Expertise: Comfort handling complex third-party APIs and external connections.
  • Infrastructure Savvy: Hands-on experience with AWS and a "DevOps mindset" (you build it, you run it).
  • Pragmatic Mindset: A self-directed problem solver who values "getting things done" and moves with urgency.
