Security Engineer 3

About Jupiter

Jupiter was founded in 2019 by Jitendra Gupta, best known as the founder of Citrus Pay. The idea was simple: why should personal finance be the one experience that isn't customer-centric That question sparked a mission to build a modern, intuitive platform that puts people in control of their money.

When we launched in 2021, over 100,000 people were already on the waitlist. Within 10 months, we crossed 1 million users. Today, 2.8 million+ users trust Jupiter to manage their finances — from automated spending insights across all their savings accounts, to the Edge CSB Bank RuPay credit card, to No-Penalty SIPs and Daily SIPs starting at 10.

We've built this on cutting-edge technology, strong data analytics, and a diverse team of creative thinkers and domain experts who share a vision for accessible, transparent, and inclusive finance. Now we're looking for like-minded people to join the crew.
