Overview:

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. This empowers our customers to focus on building amazing products and create personalized experiences for their customers, while we take care of the complexities of processing their customer data reliably at scale. With an incredibly sticky product and minimal direct competition, we’re on track to be the driving force behind powering the entire customer data ecosystem, which brings us to you.
 
The Libraries and Instrumentation team builds software that brings more than 2 billion events at greater than 1 million requests per second into Segment from millions of devices so that we can make rich data accessible to our customers. From startups to Fortune 100, businesses of all sizes rely on the Segment Platform to deliver data downstream into hundreds of streaming integrations and thousands of customer data warehouses. Instrumentation is the gateway to getting all data into Segment, which enables us to deliver amazing digital customer experiences.
 
While our analytics.js library has been around since day one, we believe it is time for us to make a step-change around how our customers add analytics to their applications and build the next generation of our instrumentation platform. This means we need to go deep and think about how applications are built, how their runtimes operate, as well as improve the developer experience of integrating with Segment.

About Segment

About us Segment is a fast-growing startup building a platform for collecting customer data. We provide a single API to track customer data across multiple devices and channels, and send it to third-party tools, internal systems, or a SQL database with the flip of a switch. Segment eliminates the need to write code to integrate new tools, which saves time and removes dependencies across teammates. By consolidating tracking to one API, Segment sends consistent, complete data to every tool and database where companies need to use it. Segment is small, so everyone has a huge impact. With just a handful of people, we’re already processing billions of API calls every month. We love open sourcing our code and writing down everything we’ve learned. If you want to make an impact, and are excited about how data can change organizations, we want you.
