The Who, What, Why and Where

At Twilio-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.

We are looking for a software engineer with mobile development experience to help craft high-performance and highly operable libraries and instrumentation projects that our rapidly growing user base will use at scale. We recently completed a full rewrite of our Android and iOS SDKs in Kotlin and Swift, and we are ready to innovate on the newly created Segment platforms.

  • Nice to have: Understand mobile performance, energy, and architecture paradigms.
  • Nice to have: Familiarity with both Android and iOS platforms.
