Join Toss Bank's Frontend Platform team where we're on a mission to 10X frontend developer productivity. We're building 'boosters' that help developers work faster through technical automation, tooling, testing, library development, and debugging environment improvements. Our team focuses on creating systems and tools that dramatically improve development efficiency - from automating manual tests to streamlining debugging processes.

We use modern technologies including React, TypeScript, Next.js for core development, along with state management tools like React-Query, Jotai, and Zustand. Our build infrastructure leverages Webpack, Rollup, ESBuild, and other cutting-edge tools. We've achieved significant improvements like reducing Docker image sizes by 90% through mono-repo optimization and implementing safety checks in CI pipelines to prevent deployment errors.

As a senior frontend platform engineer, you'll be responsible for identifying and implementing productivity improvements, fostering a culture of knowledge sharing, optimizing build/deploy pipelines, and creating developer-friendly tools and libraries. You'll work with a team of exceptional engineers in building the future of digital banking infrastructure.

The ideal candidate should have strong experience with frontend infrastructure, automation tools, and a passion for improving developer experiences. You'll have the opportunity to make significant impact on how dozens of frontend developers work and ultimately how millions of users experience digital banking.
