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, , 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.

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 milliseconds in response times?" etc.

We are looking for technically very strong candidates, with a strong understanding of computer systems. We want people who love designing and building infrastructure components and large complex services. Being a Software Engineer at Exotel takes a bit more than the following.

• A "DevOps" mindset. You own what you will develop.

Good-to-Haves

• Exposure to any Enterprise grade Billing systems.
• Comfortable scripting in at least one of PHP / Ruby / Python.
