You will be a part of: Supply Chain Management (SCM)

Myntra-Jabong Supply Chain Management systems form the backbone of our core business and customer experience. Any business runs on a simple construct of Demand (Consumer) and Supply (Producer). However, a set of complex and intricate methods, processes and systems connect the demand with supply in a deterministic and predictable way. These methods, processes and systems collectively form the Supply Chain for the business. The multi-billion-dollar Myntra-Jabong business fundamentally rests on a set of highly scalable, robust and intelligent Supply Chain Management systems that solve real-world problems of predicting the demand from millions of our customers, for a combination of millions of products from our product catalogue, and intelligently connecting that demand to thousands of national and international sellers or suppliers using a set of advanced homegrown tech products that we build and manage.

SCM engineering employs new-age technologies such as Distributed Computing constructs, Machine Learning, Deep Learning, Computer Vision, Artificial Intelligence; scalable data stores in Mongo, Redis, Cassandra, MySQL, Elastic Search, Solr; scalable programming constructs in Node.js, GoLang, Java; JavaScript, Python, and new-age frameworks such as ReactJS and ReactNative to solve some of the hardest problems in the e-commerce business
