DevOps Engineer – busuu

busuu busuu

the free language learning community

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 infrastructure to the next level, enabling our engineers and colleagues to scale and grow as much as our customers need us to.

We use AWS, Linux, Puppet, MySQL, PHP, Docker, Vagrant, nginx, Python, Ruby, solr, and many more. But we’re always open to change and the best tool for the job should be the one we’re using.

Why is a DevOps Engineer at busuu important?

Everything we do is powered by our software, and that software can’t function without rock solid, stable platforms and tooling. Our infrastructure enables our users to learn new languages, and our tools enable our Software Engineers to ship features fast and safely. We want to build on what we have to enable us to ship faster, scale quicker, and serve our expanding, worldwide user base.

What does a DevOps Engineer do at busuu?

As a DevOps Engineer, you’ll be responsible for the whole platform, from performance and monitoring to security and everything in between. You’ll be at the heart of building and maintaining the technical infrastructure we rely on every day, getting the opportunity to architect an infrastructure that already serves 55 Million users and growing. You’ll have the chance to make the tough decisions that we need to make to take us to the next level, choosing the right tools for the job and leading projects to solve real problems for both our users and Engineers.

We like to ship fast, often, and safely, and our Engineers are shipping code daily. But we think we can do a lot better, and you’ll be deeply involved and leading the charge to enhance our existing tooling and helping to enable our Engineers in their jobs every day. You’ll work closely with our Android, iOS and Web teams daily.

We have users throughout the world, and we need to adapt our platform to provide the best performance to all our users across the globe. We operate on AWS in one region, we’ve got some big plans to go multi-region, and you’d be deeply involved in this key project.
