  • Strong experience and expertise building API products. We are looking for experience with GraphQL, REST and relational databases.
  • Well-versed in concurrent programming.

  • A highly effective collaborator, you work well with your team and your partners in product and design towards common goals.
  • You possess a strong customer focus, because the feedback loop with customers will be very tight!
  • Exposure to SDLC from reviewing requirements through to debugging complex systems in Production.

  • WEAR THE CUSTOMER’S SHOES: We understand our customers needs and wants so that we can create the platform they need to be successful. We are building a visual programming language for marketers to enable them to better connect with their customers. Our platform must be easy to use and intuitive to help drive their success.

  • BE BOLD: We are all owners of the products we are building, everyone is empowered to drive the product vision forward.

  • Orchestrate a customer journey and send emails, SMS, push notifications, voice, video, whatsapp, onsite personalization – any channel that the customer prefers most with a relevant message they actually want to see.
  • Our team’s goal is to help Twilio-Segment customers understand, aid, and delight their customers across every first party touchpoint and interaction.
  • Growth Automation is being built on top of the most sophisticated first party customer data platform in the world.
  • Imagine a platform that can take the hundreds of thousands of 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.
  • We’ve since built several successful products on top of the Personas platform: Segment Audiences for real time audience management, Segment Traits for computation, and Profile API for real time personalization. Now we are building a growth automation platform.
