You have experience working with databases.  You are comfortable modelling database schemas and writing queries across a variety of data sources.

You have strong Object Orientated PHP skills and experience writing APIs and web applications.  You have a history of shipping high-quality production code in PHP and understand the benefit of automated testing to ensure the quality of the software.  You are familiar with frameworks such as Symfony.  More widely you embrace automation and take pride in helping your team be more efficient.

You have a dedicated and private space to enable home working.  You’ll need to be able to work from home without interruptions, as well as being able to travel on occasion.

You love learning.  Engineering is an ever-evolving world.  You enjoy playing with new tech and exploring areas that you might not have experience with yet.
