Job Description

Tech @ Exotel

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, Node.js, 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 the high availability
