**About us**:
Exotel is one of Asia’s largest cloud telephony companies. Our aim is to change the way enterprises look at customer communication. We build the best-in-class communication products that power the companies of today and tomorrow. Our technology enables customer communication for our clients such as Uber, Ola, Go-Jek, ICICI, IDFC, Redbus, Flipkart, Quikr, Practo, Lazada, Redmart, etc. to name a few. We are a 9-year-old company with humble beginnings. We started as a 3-member team. Currently, we are a 120-member team catering to over 3000 customers across the globe. Our technology has connected over 400 million people across the world and powered over 10 billion conversations. Read our growth story here.

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 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 high availability.

Software engineering within the Product Engineering team 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.
