The Who, What, Where and Why


Twilio is looking for a talented and experienced Technical Leader for the Twilio Flex Application Platform.  The ideal engineer is passionate about building exceptional developer experiences. You are the right fit for this role if you:

  • Have 7+ years of experience in designing, building and maintaining large-scale, highly available, cloud-based, software platforms.
  • Are an API-first developer who values the power of platforms.
  • Enjoy working with multiple programming languages and can articulate how they fit into the long term technical vision for the team and the organization.

  • Have familiarity with Javascript frameworks and languages like Typescript, React.js, Vue.js, etc.
  • Are highly collaborative and have excellent communication skills.
  • Have a degree in Computer Science or equivalent experience.

You are able to think at scale, define, and meet stringent availability and performance SLAs. You represent your customers, and you always work to enable their success.


You will be responsible for technical leadership across frontend and backend services that power the developer platform for Flex. These services run a high-availability edge service, open-source tools for frontend developers, UIs within Flex for system administrators, and APIs for extending Flex’s programmability. This team defines the primary interface that developers use to build and deploy their customizations to Flex.

In a typical week you will:

  • Be a hands-on engineer contributing to and improving our code base while raising the bar of the quality of our platform.
  • Provide mentorship to the engineering team on software development best practices and lead cross-team technical discussions and decisions.
  • Collaborate with other senior technical leads across Twilio to drive a coordinated technical direction for the platform.
  • Represent the Engineering Team within and outside the organization, both technically and culturally.
  • Partner with the Product team to design for developers and find new ways to delight your customers.
