This role will play a pivotal part in building out an internal development team, with the opportunity to step into a lead position as the team grows.
Importantly, this is not a “build from scratch” role — the platform is already established. The focus will be on maintaining, improving, and optimising existing code, ensuring performance, stability, and scalability as the business evolves.

Support and contribute to architectural decisions and long-term technical roadmap
Collaborate with product, QA, and implementation teams to deliver high-quality solutions
Maintain and optimise MySQL databases, schemas, and queries
Contribute to frontend development using modern JavaScript frameworks (React, Vue or similar)
Conduct code reviews and implement best practice across development
Support production systems, troubleshooting and resolving issues as required
Work alongside external contractors, with a view to bringing more capability in-house
Mentor and support future team members as the function grows
What we would like from you:
Proven experience as a Senior or Full Stack Software Engineer within a LAMP environment
Strong PHP development skills (Laravel or similar highly desirable)
Solid experience with MySQL, including optimisation and performance tuning
Experience with modern JavaScript frameworks (React, Vue, Angular etc.)
Strong understanding of API design (RESTful or GraphQL)
Experience working with Linux environments
Familiarity with Git, CI/CD pipelines, and agile methodologies
A proactive, solutions-focused mindset with strong problem-solving ability
Excellent communication skills, able to work with both technical and non-technical stakeholders
A passion for clean, maintainable code and continuous improvement
