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, 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 high availability

Software Engineer @ Tech @ Exotel

The job of a software engineer involves all aspects of software engineering : designing and architecting services and features, development, testing, instrumentation, deployment, stabilization and operations. You will be working on the core cloud telephony platform and products. A lot of focus in what you do will be outside of just adding features - you will be constantly thinking of "how do I scale out my cluster to twice its size with 60 seconds?", "how do I increase the platform uptime from 99.95 to 99.99?", "how to shave off a few extra millisecond in response times?" etc.
