Job Summary

In this role, you will develop a reusable UI component library and build the connection layer to customer systems while designing a unified authentication solution.

Job Technologies

Your role in the team

  • Building a UI component library that generated apps can assemble from, turning components like payslip views and approval flows into maintained, reusable pieces instead of regenerated artifacts.
  • Creating the connection layer between generated apps and customer source systems—HR platforms, time-tracking and scheduling systems, and a long tail of vendors with thin or undocumented APIs.
  • Defining extension points (widgets, menus, sidebars) so plugins declare where they surface and what they connect to in a single, clean configuration.
  • Designing and implementing a cross-integration authentication solution that lets customers run multiple integrations without forcing employees to log in repeatedly.
  • Shipping plugins on the platform yourself, staying a consumer of what we build so we catch gaps early.

Our expectations of you

Qualifications

Experience

  • Strong knowledge of React and TypeScript for frontend work Java/Kotlin or Go and TypeScript experience for backend services.
  • Real experience integrating third-party APIs, especially the challenging ones—inconsistent auth, partial documentation, legacy and on-prem systems.
