Our cornerstone products and services: slice savings account, slice UPI credit card, slice UPI, and slice business are designed to be simple, rewarding, and completely in your control. At slice, you’ll get to build things you’d use yourself and shape the future of banking in India. We tailor our working experience with the belief that the present moment is the only real thing in life. And we have harmony in the present the most when we feel happy and successful together.

We’re backed by some of the world’s leading investors, including Tiger Global, Insight Partners, Advent International, Blume Ventures, and Gunosy Capital.

About the team

Everything that you see on the internet - developers made it. Even the page that you’ve opened right now and are reading this very line from - a developer. At slice, we’re trying to build a world-class core banking product and that takes some crazy, world class engineers. A team so supportive - even if you miss a ‘;’ in your code, they got your back till the code runs successfully.

• Drive the design and development of reusable Flutter components, libraries, and shared modules that improve engineering efficiency across teams.
• Own and evolve scalable mobile architectures, making sound technical decisions around modularization, maintainability, testability, and long-term platform health.
• Drive continuous integration and delivery practices with QA and platform teams to improve release stability, reliability, and engineering velocity.
• Own mobile application performance and reliability, identifying systemic issues across rendering, memory, startup time, networking, and device behaviour.
• Lead the debugging and resolution of complex production issues, including performance bottlenecks, crashes, memory leaks, and issues spanning Flutter and native layers.
