Senior Frontend Engineer at Weaver Fintech Ltd

Role Overview

• As a Senior Frontend Engineer, you'll build and maintain the production frontend applications that merchants and consumers interact with daily, working with React 18 (TypeScript + Vite) or Vue 3 + Capacitor.
• You'll own features end-to-end — from design system components all the way to production deployment — and make technical decisions that shape how merchants manage their accounts and how consumers experience BNPL. You’ll work closely with backend and product teams while driving high standards for performance, reliability, and code quality.
• If you’re a strong TypeScript engineer who cares deeply about shipping polished fintech products that real people rely on, this is your role.

Key Responsibilities

• Build and maintain production frontend applications that merchants and consumers interact with daily, working with React 18 (TypeScript + Vite) or Vue 3 + Capacitor.
• Own features end-to-end: from design system components through to production deployment, while making technical decisions that shape how merchants manage accounts and how consumers experience BNPL.
• Define the frontend state management and API strategy, including complex auth flows, token refresh, protected routes, and resilient error handling.
• Build checkout and payment flows where correctness is critical: eliminate race conditions, prevent double submissions, and ensure reliability on flaky networks.
• Drive performance optimization at scale — fixing unnecessary re-renders, bundle bloat, and sluggish interactions.
• Mentor through high-impact code reviews, establish frontend patterns and best practices, and collaborate closely with backend and product teams to ship complex features. Use AI coding tools daily to move faster and raise code quality.

Experience and Requirements

• Senior-level TypeScript expertise with React or Vue.js (React 18 + TypeScript/Vite or Vue 3 + Capacitor), plus strong command of HTML and (S)CSS.
• Designed, built, and evolved component libraries and UI systems focused on performance, maintainability, and developer experience at scale.
• Architected state management solutions across large SPAs and made strategic decisions about the right tool for each use case.
• Led production auth flows, including token refresh, protected routes, and secure session management.
• Deep expertise diagnosing and fixing complex frontend performance problems using browser tools and systematic optimization.
• Shipped mobile + web fintech features that meaningfully improved performance, reliability, and real-user outcomes at scale.
• Built robust REST API integrations and handled real-world edge cases in a clean, maintainable way.
• Experience with frontend testing, CI/CD pipelines, and using AI pair-programming tools as a core part of daily work.
