Exotel engineering solves some cool infrastructure-level problems to ensure 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, Node.js, Ruby, Java and PHP. We use Aerospike, and 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 the high availability

What you will do?

• Develop/improve Exotel's distributed messaging/voice/Enterprise Contact Center stack.
