Technical Support Engineer- Voice United States

Company: Twilio

Because you belong at Twilio

The Who, What, Where and Why 


Twilio is looking for a Technical Support Engineer to join the U.S. Voice Specialization team, supporting our customers’ use of Twilio’s Programmable Voice and SIP Trunking products. You will function as the voice of Twilio to our customers and partners, and function as a subject matter expert for Twilio’s Voice APIs.

You should be excited by opportunities to problem solve and demonstrate a high competency in communicating complex technical issues to both technical and non-technical audiences via phone and email mediums. You should have an interest in reading and debugging code, and be able to master the design of applications for controlling voice calls via our REST API.  You should also have advanced time management skills, have the ability to work well under pressure, and be proficient at developing workflows to coordinate troubleshooting of multiple complex cases while following standard processes and procedures. You should be able to remain calm and effective at higher workloads as well as excelling at prioritization and evaluation of situational urgency.

You should have telecommunications and VOIP troubleshooting experience. For example, you may have implemented, deployed and/or maintained/supported Avaya/Cisco/or similar platforms of significant size. Alternatively, you may have experience building and supporting voice communications applications.

A firm understanding of the technology stacks common to the Web ecosystem is required. A demonstrated history of creating non-trivial applications in Java, .Net, Ruby, Python, PHP, Javascript or some other modern, general purpose programming language is highly encouraged, since much of Twilio’s functionality is exposed as REST APIs.

Continuous learning and collaboration essential elements of our Support Team, and we place a high value on demonstrated ability to work in tandem, mentor, and coach other members of the team in technical and process aspects of their jobs.


A regular day in the life of a Voice Technical Support Engineer at Twilio would consist of working on 8-10 new cases plus cases in-progress from previous days, submitted by both individual developers and major brands. Some examples include: examining packet capture data and engaging one of our carriers to resolve a one-way audio issue in Germany, providing advice to a customer whose web server is not responding to HTTP requests from Twilio, and calling a customer to discuss the design of a function for transfering calls between agents in a call center. Internally, you will be collaborating with your teammates and the Twilio Product and Engineering teams via Slack as well as filing JIRAs to report reproducible bugs, spending time reviewing internal knowledge bases to stay current with industry shifts and standards, and working with your manager to surface customer pain points to assist in process betterment.

Note: This role can be Monday-Friday Or Tuesday-Saturday.
