The candidate

We are looking for a junior data analyst / engineer to build and scale analytics throughout WeSwap as we rapidly expand in 2019. You will help deliver the second phase of a data pipeline project, trial and implement new business intelligence products, and create incisive, well-designed and accurate analyses. You will be meticulous, embrace TDD and ensure your results are always correct and reproducible.

You will love full stack data pipelines and be enthusiastic about turning your hand to anything: data engineering, visualisation, analysis and, of course, cleansing. We work with an AWS stack (Athena, Glue, Lambda, Quicksight) and Tableau but enthusiasm and potential are more important than technology-specific skills. The ability to create and productionise data pipelines and analyses is more important than formal qualifications.

Most of all, you will love working in a highly innovative, rapid iteration environment, and be able to communicate and diplomatically challenge colleagues at all levels. Data is essential to the ambitious growth of WeSwap in 2019 and this fast-paced role will give the candidate exposure to all areas of the business.
