Senior Data Scientist

Overview

Zapp is London's leading premium convenience retail platform. Founded in 2020, our vision is to disrupt the multi-trillion dollar convenience retail market, currently dominated by major players, by developing best-in-class customer-centric technology and fulfilment solutions. Zapp partners with some of the world's leading brands to deliver an exclusive range of hand-picked products 24/7, delivered in minutes.

As part of our vision, we are seeking a talented Senior Data Scientist to join our dynamic, expanding team. Over the last few years we've built a solid data foundation using best in class technologies (dbt, BigQuery, Airflow) and are just at the start of our journey to leverage this data in a more sophisticated way.

As the first data science IC at Zapp, you'll be expected to be a bit of a jack of all trades. We have a number of well defined problem areas (demand forecasting, personalisation, pricing...) and a mature toolset, but limited support on the infrastructure side. To be successful in this role, you'll need to be eager to get your hands dirty when it comes to MLOps and handle a number of responsibilities traditionally associated with MLEs.

You'll have the opportunity to work collaboratively with engineering and product to design, build, deploy and monitor the critical decision-making software and features that will help take Zapp to the next level.

This is a fantastic opportunity to get involved early, take ownership over key drivers of value and help grow a world class data function at Zapp.
