Sr. Software Engineer - Programmable Application Infrastructure

The Programmable Applications team are transforming the way builders can get started with Twilio, changing the time it takes for Twilio technologies to be rolled out from months to minutes. Our mission is to fundamentally change how Twilio is consumed.

This team builds the suite of microservices that will form the foundation of a product that can be deployed through configuration only, but retains total programmability at every layer of the stack.

The set of microservices required touch every single Twilio product, front end and back end. Powering consumer, agent, supervisor and administrations user interfaces.

This team touches everything, moves fast, and changes Twilio for the better.

 

About the job:

As a senior engineer at Twilio, you are empowered to create wonderful experiences for our customers, who are developers and builders. You are excited when you release something that makes it easier for a developer to focus on the creative side of code.

You think about how your product will help the customer that spends $10s of millions with Twilio, and the customer who hasn't spent $1 yet.

You will own, create and operate REST APIs and infrastructure to support front end user interfaces. These services will transform the way people get started with Twilio.

Your services will go from concept to sustained exponential growth in a very short period of time. You enjoy getting the MVP out the door, and you know that to take services to scale require developing a complex distributed platform and will be concerned with availability, throughput, latency and real-time responsiveness.

You will own and operate production services in AWS cloud infrastructure using the latest tools, like Datadog and Rollbar.

Senior Engineers are critical in making sure Twilio is loved by developers and builders alike, that it is easy and fun to use, and stays on the cutting edge.

You can make our customer's lives better.

  • Tackle some of the most challenging problems you can face developing highly available services in a distributed cloud environment that needs to scale.

Requirements:
