The Role

The Engineering team at Rokt is focused on building amazing experiences and solving complex problems. Our group of Engineers collaborate effectively to build great features for our customers, an awesome experience for the end user, and whilst protecting and respecting user data and privacy.

This role is to join a multidisciplinary team of web, backend, data engineers and data scientists and help build and manage the systems that facilitate efficient and trustworthy experimentation across the millions of consumer interactions generated daily across the Rokt global network. These systems enable our partners,marketplace brands and internal teams to scientifically surface insights into consumer behaviour, validate hypotheses, and steer strategic decisions, thereby creating a better consumer experience whilst driving towards a desired success outcome for the client.

The Experimentation platform is a new system created only 6 months ago, and recently broken out into a new team. In 2021 the team has multiple ambitious goals including building new features on A/B and multivariate testing, extending the utility of the platform with self-service, embedding advanced (frequentist and Bayesian) analytics and reporting, whilst maintaining service reliability. All these bring about interesting challenges that requires a special breed of passionate, inquisitive and pragmatic engineers!
