Purpose of the role

Opensignal’s business is built on data. As a member of the Data Science team, you will work in collaboration with our Engineering team to create, analyse, interpret and report on our Metrics to quantify the quality of mobile network operators around the globe.

The Data Science team are architects of numerous data-gathering and interpretation initiatives. For example, in the last year we released a mobile games experience metric, and previous years voice and video experience metrics – all firsts in the industry – and we continue to design new measurements that are key to analysing the experience of mobile customers, such as first to report actual 5G user’s speeds.

You will model scenarios for producing new metrics as driven by our Product team and business stakeholders. You will need to think carefully and laterally, examining possible solutions whilst questioning if there is a better way of doing things. It’s a process of iteration to get to the solution, in partnership with the wider technology teams.

Apart from designing new metrics, there is the work associated with collecting billions of data points every day, from our Apps and third-party Apps. A critical aspect of the team is to ascertain the quality of incoming data, understand likely causes of anomalies, build rules that sanitise the data, perform statistical analysis for our Marketing and Sales teams or external clients, and build tools that automate our Data Science analyses.

You will also get exposure to many other parts of the business, working closely with our Data Engineers, Android & iOS Engineers, QA Engineers and our Product and Program Management functions.

As a Data Scientist, you will be responsible for

  • Creating big-data analyses that are developed into new metrics and dashboard analytics for our mobile network clients
  • Designing and implementing internal dashboards and analytics that explain our metrics development and provide actionable insights for customers
  • Translating business and customer requirements to data science analyses, and communicating these effectively with technical and non-technical stakeholders
  • Creating ad-hoc or automated analyses and developing effective models to evaluate the quality and integrity of our data and client deliverables
  • Evaluating the robustness of recommendations and reproducing analysis, to influence the direction of product development within cross-functional teams
  • Working cross-functionally with Mobile, Engineering & Product members to create improvements in the tools and techniques to help scale our analyses
