Our Ideal Candidate

Our ideal candidate for Software Engineer (L3), Developer Interfaces in Bangalore, India will be responsible for development of the Twilio CLI and Helper Libraries.  They will be responsible for continuing development and feature enhancements across a broad set of programming languages (Java, node.js, Go, Python, PHP, Ruby, C#) keeping them current to the expanding Twilio APIs and continuous updates across these languages. Twilio CLI development is in node.js, so candidates with more experience there will be better qualified, but good balanced language skills across 2+ of the languages above will be better than focused experience just in node.js.


Beyond our Twilio Magic and other core competencies, you should know that we need to have someone with:


A High Quality Bar

With the CLI and Helper Libraries being used both by internal and external customers of Twilio, the need for high quality products is paramount. The Software Engineer (L3) role is key to the delivery of this quality, making certain that the code meets the Twilio bar, that test coverage metrics are met, that tests are comprehensive, and that deployment is error-free.  This code runs in our customers’ environments - we do not want it to be the root cause of incidents within their systems.


People Management Scale

This role is an IC role and will have no DRs.  That said, they are expected to mentor and coach less experienced engineers in the processes and skills that make high-quality, highly functional software a reality.


A passion for continuous learning

The Developer Interfaces team is one of a few teams within Twilio that do not focus their development through a single or a couple programming languages. The current set of supported languages is 7 in number and will grow. There is no expectation that the candidate will have deep experience in all these on entry, but must possess a passion for becoming an expert across them all in time.


Empathy for the Developer

The candidate will have a keen sense for what our developer\-customers need, how they operate, and what Twilio must do to make their path to use Twilio’s platform as easy as it can be. Twilio-enabling applications is what the Developer Interfaces team aims to do, and the candidate must think as the customer every day.


Other Considerations

  • Experience with open source communities is a plus.  If the candidate has experiences as a contributor or a supporter, a deeper understanding of this should be explored.
