Work Mode: Hybrid (flexibility + collaboration)
We’re looking for someone who:
- Has deep experience in Golang and backend architecture
- Understands system design, scalability, and distributed systems
- Enjoys solving complex technical challenges in a high-impact environment
● You have good understanding of the fundamentals of data science/algorithms or
software engineering
● Preferably you should have done some project or internship related to the field
● Knowledge of SQL is a plus
● A deep desire to learn new things and be a part of a vibrant start-up. You will
have a lot of freehand and this comes with immense responsibility - so it is

Have you ever felt the need to see the direct impact of what you do? Then consider this:
Currently, there are 70+ million Small and Medium Enterprises in India. And they need all the help to succeed against the continuous onslaught of much larger businesses.
Imagine a jewellery shop owner in Ghatkopar Mumbai. He may be procuring his goods that are to be sold in the shop from a fixed set of vendors - some his relatives, some that people have recommended and some that came and pitched to him. He may not have ever seen the kind of designs and products that a supplier from Mysore can offer. Or the credit terms that another supplier from Surat can offer. Putting him on a platform where he can easily browse products and build new business relationships is a life-changing proposition for him.
We believe that technology should be accessible and usable for these SMEs so that they can grow and simplify their business, and compete in a fair field.
If making the lives of businesses in India and the world simpler excites you, then this is the
perfect opportunity!
You will be solving challenging problems, defining your own charter and be the master of your own growth. The best way to predict your future is to create it.
We have more than 170k businesses on our platform already with great engagement numbers. We are backed by the top founders and VCs in the country(Titan Capital, FirstCheque).
