Job Purpose

As a Junior Data Engineer in Ocado Smart Platform, you will be responsible for expanding and optimising our cloud based Data Lake architecture. In this position, your responsibilities will include designing and building data marts to serve specific business lines, creating best practises and defining data processing strategies for our Platform.

You will work with an exceptional team of engineers, as well as a product owner to identify and scope projects, plan those projects and effectively communicate advanced technical issues and findings to a range of technical and non-technical internal audiences. You will be an advocate of a Data Driven Company paradigm and will be able to evangelize others about data processing best practices and share the knowledge. You will have a chance to  work and cooperate with various development teams to deliver specific features and remove blockers to launching new clients.
