  1. Building advanced UI Frameworks to be the best payments SDK in the world:

    Juspay’s ‘Hyper SDK’, a micro app platform enables native app experiences using JavasScript/PureScript. It is a well architected system that enables isolated and parallel deployment of UI features rapidly; using dynamic over-the-air updates.

    Though it is similar to React Native, the quality and stability requirements of Hyper SDK should surpass typical open source projects. And it should have features that our multi billion dollar business partners value as advanced tech.

  2. FRP Frameworks to build Immersive UI for Creation / Operations:

    To ensure seamless customer experience specialists require a relentless focus on right information and actions. Complex dashboards and tools provide effective orchestration, enabling creators and optimizers to build and operate large scale financial products/systems. Can such highly critical operations be made immersive and delightful?

    With a wide range of complex business use cases, an array of visual ranges from a smartphone to LED walls and inspiration from fundamental technologies, we are looking at a plethora of aesthetic possibilities!

    With our growing scale and diverse use cases, we are looking for first-principle thinkers and problem solvers who can architect experiences!


  • Interested in architecting large scale frontend projects and frameworks using deep technologies like Functional Programming, FRP, Flux architecture etc.
  • Interested in understanding the systems internals of rendering, GPU, View compositing etc. to create stable and fast UI frameworks (Android, iOS and Web)
  • Passionate about unifying and developing reusable components/libraries using FP primitives
  • Obsessed about creating pixel perfect UI and crafting delightful experiences. (Why not a framework developer can also develop an aesthetic eye for visual structure and movement - animations!! )
  • Excited about building immersive experiences. Think Beyond 2D screens? ;)
  • Willing to be the part of the team that is building the payments backbone in India targeting 50M txns/day with 99.999% availability.
