Front-end Engineer (Any level)

As the largest social network for language learning in the world we’ve already had some great success, but there is so much more that we want to build and improve on. We’re looking for smart, agile, independent engineers who can help us take our web product to the next level, enabling more amazing ways for our users to interact with each other and learn even more.

Why is a Front-end Engineer important at busuu?

While native mobile apps are a massive growth area for us, the majority of our users still experience busuu through the web. It’s also our longest serving platform, having been at the core of the busuu experience right from the start. It is incredibly important for us to continue building a great web user experience, both now and into the future, and to find people that are passionate about web technologies in general.

As a Front-end Engineer you’ll be responsible for all the web products at busuu, you’ll be responsible for the code, UI and UX of 4 different projects. Our team is still small enough that every engineer makes a massive difference.

At busuu, there’s no server side rendering, our Backend team provide APIs and as Front-end Engineers our daily work is to interact and implement such technologies in the client.

What does a Front-end Engineer do at busuu?

We trust in people who have a desire to learn and share, we’re looking for Engineers who want to make a difference by creating smart and reusable components. You’ll be working on implementing new features working in sprints. We’re looking for people who have passion for the user (UI, UX) but also who are interested in performance and code scalability.

You’ll be working in a team of 4 Engineers from different backgrounds, and you should be willing to adapt and suggest improvements to an existing codebase. We’ve got many features planned for 2018 and we’re looking for people who have experience with Single Page Applications, working on real time interactions and creating friendly user experiences. You’ll have the full support of the rest of the Front-end team, allowing you to lead projects with an experienced team of senior engineers to guide and learn from.

You’ll be working closely with Product Managers and Designers on our key web platforms. Our Homepage Platform is our static file based CMS, serving as the entry point for all users as well as our payments platform. Once a user is authenticated, they’ll use our single page Webapp to learn their chosen language, update their profile, access social features, and more. 

We work closely with our Education Team colleagues too, providing tools to manage the course content for the different clients (Web, IOS and Android), and recently we created a custom CMS using React to enable them to work faster and more efficiently.

The final platform we’re responsible for is a B2B platform, where an institution can manage classrooms or groups of students and see through extensive reports their organisations usage of busuu.

To deliver all these disparate platforms, we use many different technologies and we’re always looking to use the right tool for the job. We currently work with Webpack, Babel, Browserify and Gulp in our Front-end environment and we widely use ES6/ES5 across all projects. We’re big fans of Sass for our views. We currently maintain a handmade Vanilla JS helper built in house and we also use React, Redux, Lodash. We’re actively planning a migration away from Angular 1.6 to either React or Vue.js.

We recently wrote an article about the refactor of our homepage project on our tech blog: How we rebuilt busuu.com — A Front-end Case Study

Not ticking every box or think you’ve got that unique set of skills we haven’t realised we need? Get in touch anyway; we’re always looking to add great people! There are lots of indications that some people only apply to roles when they meet all the qualifications for a role, however we’d encourage you to apply even if you don’t believe you meet all the criteria!
