The client also prioritise the development of their staff, with every employee having a personal development plan, tailored to them, with financial incentives based around reviews and milestones. There is also budget and resources available to support this development.

The ideal candidate will have a thorough understanding of software development principles such as SOLID which allow you to pick up and apply new tools and technologies quickly.

To be considered:

* 2+ years’ commercial experience in PHP & Laravel

* Experience with best practice ie SOLID principles & Design Patterns

* Experience with relevant frontend frameworks/libraries (preferably but not exclusively Vue/Nuxt.js or React/Next.js)

* Experience with Unit Testing/TDD

* Agency experience would be a bonus not but not required

The company in question is a market leader not only in the solutions that they provide to their clients internationally but also the technology the work on and the environment they create. They aspire to create a relaxed environment where people can work on forward thinking technology solutions.
