Do you enjoy shipping something you brainstormed, architected, designed and built? Are you always striving to find the simplest solutions to the hardest problems? Do you think code that doesn’t have tests is by definition legacy code? Then you sound like the person we’re looking for to join our backend engineering team.

What is Tonsser? 

Tonsser is the leading app and platform for youth football players with more than 1.3m players using the app to unlock their potential. The focus has been on building an excellent user experience that motivates, inspires and empowers players to be the best they can be and share it with the community... and discover life-changing opportunities.

With the vision of democratizing the football industry to create equal access to opportunities, we make it possible for players to build identity and capture their performance through stats and video to compare with the community and earn attention from both local and global clubs.

But that is just one part of Tonsser. We know that football is not only about getting discovered, most players have that dream, but play with the objective of having fun with their team. We have built a community that shares our values and aims to revolutionize the next generation of footballers.  

Backend engineer at Tonsser

As part of our fast growing football platform, we have many exciting challenges in scaling our backend infrastructure and building new product features for our users.

You will join the Backend Engineering team of Tonsser, the owner of our API, which is used heavily by our client apps (iOS, Android, React). The Tonsser API is built in Ruby on Rails, where we recently hit 100K LOC (with an additional 100K LOC of tests), so it’s a big system. The API is mainly hosted on Heroku, but AWS is also utilized for file storage and video transcoding. We use PostgreSQL as our main database, but also rely on Redis for caching/async jobs and Elasticsearch for search.

Besides working with the current Tonsser REST API, we have are going new ways to scale the Tonsser backend, by creating a new GraphQL API. Tonsser also has a huge scraping setup, run by our Match Data team, and working alongside the API team.

We embrace automated testing (TDD) and over 4.000 tests being run every time a new commit is added to our code base. We use CircleCI for our continuous integration pipeline, which allows us to test new changes quickly and deploy to our production environment several times a day.

When we build something, you’ll be part of the process from brainstorming all the way to shipping, and beyond, to seeing how it performs.
