  • Own delivery management, organizing team workflows to turn ready requirements and designs into a working Release Candidate (MVP) within 3 months
  • Ensure native-like UX and resilience, delivering instant UI feedback and stable performance even under poor network conditions (e.g., intermittent 3G/Edge)
  • Adapt the application for iOS, providing a fully native-like experience while working around mobile Safari limitations (cache resets, navigation quirks)
  • Collaborate closely with the backend team to define API contracts and optimize requests for web performance
  • Own quality and infrastructure, including Core Web Vitals performance metrics and CI/CD pipeline setup in collaboration with DevOps engineers


  • It’s all about you
  • 5+ years of commercial frontend development experience
  • Expert-level proficiency in Vue and TypeScript
  • Strong hands-on experience building Progressive Web Applications (PWA), including Service Workers, Web App Manifest, and Cache Storage API
  • Experience designing frontend architecture from scratch (greenfield projects)
  • Hands-on experience handling unstable network conditions (e.g., intermittent 3G/Edge), including retry mechanisms, connection loss handling, and proper error states
  • Experience solving platform-specific challenges for iOS/Safari PWAs (cache eviction, background limitations, navigation quirks)
  • Strong understanding of the PWA lifecycle and seamless application updates
  • Solid understanding of performance metrics (Core Web Vitals) and optimization techniques
  • Would be a plus

  • Experience configuring advanced caching strategies using Workbox
  • Experience setting up basic CI/CD pipelines in collaboration with DevOps engineers
