About the company- FPL Technologies
Credit cards haven't changed much for over half a century so our team of seasoned bankers, technologists, and designers set out to redefine the credit card for you - the consumer. The result is OneCard - a credit card reimagined for the mobile generation. OneCard is India's best metal credit card built with full-stack tech. It is backed by the principles of simplicity, transparency, and giving back control to the user.
The Engineering Challenge
“Re-imaging credit and payments from First Principles”
Payments is an interesting engineering challenge in itself with requirements of low latency, transactional guarantees, security, and high scalability. When we add credit and engagement into the mix, the challenge becomes even more interesting with underwriting and recommendation algorithms working on large data sets. We have eliminated the current call center, sales agent, and SMS-based processes with a mobile app that puts the customers in complete control. To stay agile, the entire stack is built on the cloud with modern technologies.

About the company
Currently we are hiring for a VC backed startup a fast growing fintech startup based in Bangalore.
It is a super app to digitize India’s 50M+ sales agents where they can get access to relevant products & services, receive training through interactive videos on “how to sell, what to sell and whom to sell”, and earn money. For businesses, we help them save a huge effort in managing and training these agents and help them increase their reach to every nook and corner of the country.
India is a trust deficit market which cannot be accessed through Internet Marketing on Facebook and Google as the majority of the customers need training, push, motivation and a primer on why and how to use a product.
To solve this problem, traditional industries like BFSI, Telecom, Automobile, Real Estate etc. use 50M+ frontline sales executives to drive distribution. We believe that not just for these traditional industries but also for emerging companies in FinTech, EdTech etc these agents will play a pivotal role in accessing trust deficit customers.
They have grown to a 100,000+ agent network across India (growing 50% MoM) & are funded by tier1 VC’s and angels in India.
