Only 10% of India speaks English and 90% speak over 25 languages and 1000s of dialects. The internet has largely been in English. A good part of India is now getting internet connectivity thanks to cheap smartphones and Jio. The non-english speaking internet users will balloon to about 600 million users out of the total 750 million internet users in India by 2020. This will make the vernacular segment one of the largest segments in the world - almost 2x the size of the US population. The vernacular segment has very few products that they can use on the internet. One big need is that of sharing thoughts. Twitter serves this need globally through a micro-blogging platform. However most of the Tweets are in English and the vernacular Indian feels out of place on it. To solve that problem, we started Koo.
About The Company
The app is a micro-blogging platform in Indian languages. It is an app built in India, for Indians, to share their thoughts and opinions on any topic in their mother tongue using Audio/Video/Text. Koo gives a voice to Indians and enables the “Best of India” to share their thoughts with the “Rest of India”. We provide a personalised feed to users by letting people select the people they want to follow. The user is then shown content from these people. Some of the top minds of India are invited to share their thoughts and opinions on various topics. Users can follow such personalities and follow what they are talking about, and share their opinions too.
We are a Series A venture funded company. It has raised $6.5 million from stellar investors like Accel Partners, Shunwei Capital, Kalaari Capital, 500startups and Blume Venture Partners.
Technology Team & Culture
Nishant (CTO), has headed engineering for large and complex platforms like Coverfox and CitrusPay catering to the needs of millions of consumers. Technology team comprises sharp coders, technology geeks and guys who have tried entrepreneurship or are very entrepreneurial in nature and extremely passionate towards technology. Anyone being part of a technology team will have a lot to learn from their peers and mentors. Download our android app nearing 1 million downloads from play store and take a look at what we are trying to build. Technology stack compromises of a wide variety of cutting edge technologies like Elixir, Java 11, Reactive Programming, MongoDB, Neo4j, Kubernetes, AWS, NodeJS, Python, ReactJS, Redis, Aerospike, ML, Deep learning etc. Working hard & party harder is the mantra that we believe in.
Technology skill sets required for a matching profile
1. Work experience between 2 years to 8 years in building large scale high user traffic consumer facing applications with desire to work in a fast paced startup.
2. Knowledge on reactive and asynchronous programming is preferable. If you have worked with coroutines, goroutines, high concurrency or optimized number of threads for processing on your backend server you could be a good fit.
3. Extremely proficient at writing performant, scalable and production ready code in Kotlin, Java (8 or above, comfortable with concepts like lambda, streams, multithreading etc), Elixir, Rust, or Golang. Should be familiar with static code analysis, code coverage and code reviews.
4. Experience with NoSQL DBs like MongoDB, Cassandra, Redis or Aerospike is required.
Knowledge of graph DBs like Neo4j is preferred.
5. Strong in algorithms, problem solving and data structures.
6. Knowledge of TDD and experience with building applications integrated with CI-CD pipelines (automated build, tests and deployments).
7. Exposure to micro-services with good understanding of containers, kubernetes, logging, alerting and monitoring. Inter services communication. Should know how to handle multiple versions of APIs.
