Data Scientist

at busuu Ltd in London

Position Scope

At busuu we have over 60m users around the world learning and improving their language skills through our social media platform and bespoke content. All of this user activity generates a lot of data; we are looking for a Data Scientist that will strike a perfect balance between investigating and researching the patterns within this data with academic rigour and constantly delivering revenue driving insights and data products.

We constantly work on many business challenges that can be solved with data, and we always use bleeding edge technologies and machine learning techniques to understand our users, help them learn faster, and enable even more beneficial social interactions on our platform.

Why is a Data Scientist at busuu important?

At busuu, data is our main view of our users. As a Data Scientist, you de facto become the one closest people to our users as qualitative and quantitive data turns into a user narrative within your head. You'll work closely with product owners, developers and business stakeholders to commission and model data for the purposes of analysis, prediction and optimisation, giving us insight to move our business in the right direction.

What does a Data Scientist do at busuu?

As a Data Scientist, you'll be involved in the entire flow of data throughout the company, as well as creating bespoke machine learning systems operating in production. Data Scientists at busuu also help to identify and optimise user and marketing flows, detect payment fraud, assess the impact of new content to increase engagement and help users find the best connections within the community using classification, clustering and regression techniques.

You will use Python or R, SQL, Amazon Redshift, Tableau or any other tools that you deem necessary for the job to either advise the team to the best business decision, or create a predictive model in production to make decisions automatically, ensuring that users have the best experience possible, and achieve their language learning goals.

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! We don’t believe that ticking off a list of skills is the only thing that makes a great candidate. You can read more about how we're building a more diverse team on our tech blog.
