SE-2 (Voice Backend)

• Exotel Engineering solves some really cool infrastructure-level problems with the goal of ensuring no one misses a call or an SMS
• Our focus is on building a very fault-tolerant, loosely coupled, scalable and real-time distributed system
• We are generally agnostic of language, technology or tools
• Currently, our tech stack is built on Golang, Nodejs, Ruby, Java and PHP
• We use Aerospike, MySQL as data stores, ElasticSearch for search and Beanstalkd for queuing
• We emphasize a lot on clean abstractions of code, loosely coupled services and good coding practices
• We are very strong believers in "you built it, you own it!"
• And running a distributed system is very different from just building one
• We are crazy about high availability
