Ever thought about leading a bunch of extremelytalented engineers working onengaging and beautiful applications on mobile and desktop platforms? How about branching out to VR and AR? Do you liketo work in a fast-paced environment with a fantastic product team? Do you feel like your current job is just a job and you have to fight for flexible hours, ability to work from home, and your innovation time is reduced to an occasional hackathon? Are you tired of various business stakeholders treating you like a waiter in a fast-food restaurant? If the answer isyes, then read on and hit that ‘Apply Now’ button, because we are different!

At Concrete we work hard to create a perfect environment for our engineers. We don’t have a Michelin star chef to serve your lunch but we do have an established working from home policy so you can spend more time with your family. We also don’t have a barista on-site to serve your almond milk latte, but we are flexible – you can start your day in the office at any time providing you make it for our daily standup (because it is important! and yes, we do have a very good coffee machine).

This time we are looking for aSenior Fullstack engineer to take ownership and guide ourmulti-skilled developmentteam. You will be working alongside management and the backend lead to deliver applications for a new retail platform using the very latest JavaScript technologies and Frameworks.

We are constantly building new applications for our clients – Marks and Spencer, GAP and many more. Working on a real-time collaboration software is challenging – you will have to learn new technologies and prototype new apps at a speed of light, but not because it is a high-pressure environment, simply because you like to see your code working in production. That said, we don’t tolerate sloppy coding – for every single line of code we write, there is almost always a line of unit-testing code.

If you’re a frontend lead right now or a driven senior engineer with a burning desire for a career progression and a skillset to match – get in touch!
