Segment, San Francisco

See jobs at Segment



At Segment, we believe companies should be able to send their data wherever they want, whenever they want, with no fuss. We make this easy with a single platform that collects, stores, filters, transforms, and sends data to hundreds of business tools with the flip of a switch. More recently, we also developed the ability to let customers enrich their data in real time using computations they specify. Our goal is to make it easy to understand, extract value, and protect the integrity of data. We are creating a world where engineers spend their time working on their core product, letting us take care of the complexities of processing their customer data reliably at scale. We’re in the running to take over the entire customer data ecosystem, and we need the best people to take the market. 

Who we are:

We're a small distributed team of full-stack engineers based in San Francisco and Vancouver who love to ship high-quality code.
From collecting data through analytics.js, to building powerful tools for data governance, to implementing algorithms that can handle complex billing scenarios at scale, to optimizing Sign Up conversion, the Gateway team is focused on creating a fantastic user experiences.
We're looking for talented engineers that are passionate about building world-class experiences that delight our customers.

What We Do:

  • We enjoy building UIs in React so much that we created our own internal components library.
  • We believe in using the best tool for the job. We write customer facing features using React, NodeJS and GraphQL. Our write-heavy traffic services are written with Go and leverage multiple data storage solutions.
  • We deploy our code multiple times per day. We "semver" everything :)
  • We love conferences. (One of our engineers spoke in 4 different countries last year!)
  • We love open source: https://open.segment.com
  • We’re proud of the code we write, but we’re not dogmatic about methodologies or techniques. We believe building the "right thing" is more important than building things "right".

Who We're Looking For:

You can turn complex business requirements into working software that our customers love to use.
  • You're proud of the code you write, but you're also pragmatic.
  • You know when it is time to refactor, and when it's time to ship.
  • You're focused, driven and can get challenging projects across the finish line.
  • You're empathetic, patient and love to help your teammates grow.
  • You have experience running apps in production and take software engineering practices seriously. You write meaningful tests and understand the value of great logging, proper monitoring and error tracking.

Project You Could Work On:

  • We collaborated closely with our BizOps and Design team to rebuild all parts of our billing experience, from the customer’s first visit, to building a pricing simulator tool, to implementing algorithms that can handle complex billing scenarios at our scale.
  • We’re building an open-source version of our UI library that saves our engineers multiple hours of work every week. Think pixel-perfect implementations by default .
  • We used a HLL to scale an analytics tool that handles thousands of requests / sec.
  • We're building powerful tools that help our customers protect the integrity of their data, and the decisions they make with it.


  • You can write both client side and server side JavaScript using the latest APIs and language features.
  • You have some familiarity with Golang or are excited to learn it.
  • Minimum of 3 years of industry experience in engineering or some cool projects on GitHub you think we'll love to check out.
  • You provide a deep understanding of the complexities involved in writing large single-page applications.
  • You show evidence of exposure to architectural patterns of high-scale web application (e.g., well-designed APIs, high volume data pipelines, efficient algorithms.)

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.
