This role is a chance to remain hands on with the codebase, whilst managing a team of passionate engineers who genuinely care about what they do.


Driftrock was started with the aim of making marketing better. There’s no excuse for being chased around the internet by images of products you’ve already bought!

Instead, Driftrock's software glues together data to build a picture of the customer to help deliver useful marketing messages across advertising, messenger chat and websites, while helping protect privacy.

We're located at the base of the Shard, next to London Bridge station, although have a flexible working policy. Engineers often work remote or home when needed.


Driftrock’s tooling provides our users with a way to receive, transform, track and optimise leads and actions from various marketing channels. We glue this data together on the fly to build a picture of the customer.

The technology is a mixture of Elixir, Rubyand React applications hosted on Kubernetes and Google Cloud. We make use of Redis and Postgres for data storage and RabbitMQ for event processing.
