You may have heard of the cliche that teams call themselves a startup within a startup. Except that the selfserve engineering team is fairly young at Cloudflare with established ROI. You will be the founding data engineer for the team.

What youll do

This is a highly autonomous role that enables the selfserve team to personalize user journeys through precise targeting.

Think of a user that clicked X visited Y and purchased Z. We want to predict what they want to do next and then offer that next product in a live product A/B test to improve conversions. If you have worked with tools such as Posthog Amplitude Heap or better yet have built something similar we want to hear from you. Our primary usecase is to capture and process thousands of user events in a native architecture and then serve it to internal audiences both for productional usecases and for internal reporting.

You must be comfortable with setting up data lakes understanding A/B testing architectures and building the cloud tools that you may have otherwise used in the past. Because Cloudflare is the cloud that we sell to our developers.

As the founding data engineer you will have the opportunity to pick an existing data architecture to build upon build a new one from scratch or choose a hybrid approach. You tell us what the best system looks like. You will learn about the many data tools and architectures that are being used across the company traditional databases modern architectures to manage 20 of the internet traffic BI summaries realuser monitoring offered to our customers.
