About us 

The Square is a smart platform that empowers companies to manage their contractor workforce super easily and help then make informed, data driven decisions.

Since our launch in 2017 we’ve become one of the fastest growing networks of construction professionals and organisations in the UK. We have thousands of companies and tens of thousands of professionals using The Square.

We are a growing team of self motivated, fast thinking (and acting) doers. We have backgrounds from the world of tech, marketing and construction and from different parts of the world.


We know culture is not what we say it is - it is the manifestation of our collective beliefs and actions. We don’t want to force a culture on anyone, in fact it’s the differences in people that creates an awesome culture. We celebrate that. That said, we like to believe our founding values and principles are shared. Be friendly, fun, fast and collaborative, be entrepreneurial, be trusted and never stop innovating.

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.


Back-end API was built using Python 2.7, Django 1.9.6 with Django Rest Framework 3.4.6, PostgreSQL 9.5, Swagger. Running on Nginx + Gunicorn, hosted on AWS EC2 (t2.large).

Front end web app was built using: AngularJs 1.5x, REST APIs, HTML5, CSS3, Bootstrap, NodeJS. Running on express 4.14 + pm2, also hosted on AWS EC2 (t2.large).

We've also used GoNative for transforming our Web App into a Hybrid App for iOS.

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 - 7+ years experience in web development.


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 and will collaborate with other team members to create awesome new features for our users. 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.
