At Segment, we believe companies should be able to send their data wherever they want, whenever they want, with no fuss. Unfortunately, most product managers, analysts, and marketers spend too much time searching for the data they need, while engineers are stuck integrating the tools they want to use. Segment standardizes and streamlines data infrastructure with a single platform that collects, unifies, and sends data to hundreds of business tools with the flip of a switch. That way, our customers can focus on building amazing products and personalized messages for their customers, letting us take care of the complexities of processing their customer data reliably at scale. We’re in the running to power the entire customer data ecosystem, and we need the best people to take the market. 
As a Software Engineer on the Personas team, you’ll lead the design and building of pipelines that process hundreds of thousands of requests per second, build realtime identity graphs, and compute billions of data points an hour. You’ll also be responsible for mentoring, sharing knowledge, and guiding the technical decisions of the team to set us up for long-term success, both as a product and as a team.

Imagine a platform that can take the hundreds of thousands messages entering Segment’s pipelines every second, add in a new identity graph, and overlay multiple high speed realtime and batch databases — and you have the Personas platform.  Since we released it a few years ago, we’ve built several successful products on top of the Personas platform — Segment Audiences for realtime audience management, Segment Traits for computation, and Profile API for realtime personalization.  Now, we’re making the next one.
