About Card91
Card91 is simplifying business payments by providing a plug and play issuance infrastructure to businesses for domestic and cross-border payments. Our full stack platform enables businesses to gain control and visibility into their payment flows, controlling the entire payment lifecycle from onboarding, to issuance, to transaction and data reconciliation. The platform aims to provide holistic solutions around payment issuance and distribution management. Our deep focus in payments will help us in bringing new issuance formats as well as technologies to businesses.
The company has been founded by seasoned technology entrepreneurs who have founded successful companies like Myntra, Mastiff Tech earlier. Headquartered in Bangalore, with presence in Mumbai and NCR, Card91 aims to disrupt the payment infrastructure space in the issuer-processor segment.
About the role
Our core issuance and processing system runs on Java. This system is responsible for powering the card issuance and management user experience as well. We are using Spring Boot stack for building our services.
The issuance backend team will be a small team of 2-4 developers, with a meaty responsibility to bring the user experience to life. It will be a hands-on role where every member of the team enjoys writing high quality code, and thrives on each other's experience.
