What we look for

This is a key role in the business, responsible for our most valuable asset - our best in class platform. We want an experienced and creative full stack developer to own our platform. You’ll have the freedom and autonomy to design and build features how you see best. You’ll work with the senior team to plan the product roadmap then manage feature development and documentation through Jira. 

This is a pretty awesome opportunity for the right person and a great opportunity for a mid/senior developer to go to the next step and own and lead a well established tech platform.

Key responsibilities

Be familiar and confident in our tech stack - fluent in AngularJS with a good creative design and query optimisation skills. Good technical communication - 5+ years experience in web development.

Responsibilities: You’ll be responsible for The Square’s product. You’ll understand our wider objectives and will work with the senior team to create, manage and build the product roadmap. You’ll be responsible for the architecture of the platform and the development of its features so it’s fit for purpose both for now and in the future. You’ll be writing high-performance AngularJS code. You'll collaborate with other team members to create awesome new features for our users, create new algorithms and optimise existing code. We're all about the user experience - our product must be the best in class. We’re looking for someone that likes to think out of the box, sees the bigger picture but rolls up their sleeves and gets stuck in too.


We're all about the user experience. We're building a global brand and the main touch point is our product so it must be the manifestation of our brand. We want a creative, agile and ambitious developer that creates awesome user experiences.
