As a Principal Engineer at Rokt you will be a technology thought leader across several teams. You will be the technical owner of several components of the overall Rokt product and be responsible for the delivery of features as well as driving technical excellence.

This role will give you a massive scope to have a serious impact on the technical direction and continuously raise the bar of the overall engineering function at Rokt.

Playing at a market-leading scale, you’ll have an opportunity to deep-dive into some of the most complex and innovative systems around.

In practice, you’ll have the chance to improve and build on a system that already has over 35,000 containers in production, deals with Petabytes of data, 2.5bn individual ecommerce transactions per year, the largest Kubeflow pipelines in the world, and systems that routinely deal with 10,000+ RPS, and continues to scale

All of that data that we process goes through Machine Learning and Deep Learning algorithms and models, all built and trained in-house, to ensure peak relevancy for consumers, and are constantly being improved upon, which results in one of the most advanced and mature Machine Learning practices in the world.
