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.

If the following broad attributes sound like you, we would love to talk to you
-
4-6 years experience in backend services in Java.
-
Strong understanding of relational databases.
-
Ability to develop clean data models for complex problem domains.
-
Pragmatic approach to architecture and design - knowing when it is ok to deviate from
said best practices in the interest of practicality.
-
Above average writing and communication skills in English. Enjoy writing crisp and understandable documentation.
Why you should join
-
You enjoy working in smaller teams. We are a startup, and we believe that smaller teams are a super-power. There is lesser management overhead, and more talk about the work that matters.
-
You care about end-user and developer experience - and how the backend impacts that. Working backwards from what the user experience demands, rather than giving up to the path of least resistance.
-
We pay well (above market average). We are sufficiently capitalised by some prestigious investors in the Fintech space and we are looking at the long game. It is a fun and exhilarating journey ahead and we look forward to having some great team mates!
