Yelps Telephony team is hiring a Software Engineer to help build and scale the telecom platform that nearly all of Yelps revenue flows through. Our platform is built on Twilio Flex and AWS and its used daily by thousands of sales and support reps to connect with businesses. Were a small team with a large footprint: the tools we build drive customer acquisition retention and revenue recovery across multiple business organizations.

A growing part of our work is in Voice AI.
