ABOUT THE ROLE We're building the next generation of cross-border fintech infrastructure — powering payments, KYC, and global merchant experiences. As a Senior Frontend Engineer (4–6+ years), you'll play a critical role in shaping both our frontend platform and mobile SDK ecosystem.

WHAT YOU'LL DO Build Core Product Experiences • Own and build checkout SDKs across payments, investments, and KYC workflows • Build and maintain SDK integrations across web, mobile, and WebView surfaces used by merchants • Contribute to shared platform concerns: design system and theming (multi-tenant / white-label), monorepo and shared packages, build tooling, observability patterns Drive Engineering Quality • Improve performance across the stack (Core Web Vitals, rendering, bundle size) • Implement best practices in testing, CI/CD, code reviews, and documentation • Collaborate closely with product, design, backend, and compliance teams PLATFORM + MOBILE OWNERSHIP (WHAT MAKES THIS ROLE UNIQUE) • Own and manage React Native and Flutter SDKs (builds, releases, merchant support) • Ensure seamless WebView compatibility across mobile checkout flows • Set up and scale real-device E2E testing infrastructure • Work with external partners (agencies) and gradually bring mobile capabilities in-house • Contribute to shared components, design systems, and frontend platform infrastructure (~30%) AS YOU GROW • Architect scalable frontend systems (design systems, multi-tenant white-label, SDK distribution) • Mentor engineers through code reviews and technical guidance • Influence technical direction and tooling decisions • Contribute to hiring and building the engineering team WHAT WE'RE LOOKING FOR EXPERIENCE • 4–6+ years of professional frontend development experience • Strong experience building production-grade, customer-facing applications • Solid foundation in React, TypeScript, and modern frontend architecture • Demonstrated stability (2+ years in at least one role preferred) TECHNICAL STRENGTH • Deep expertise in React (hooks, performance, composition) • Strong TypeScript — generics, discriminated unions, inference, typing real-world data • State management with Zustand and TanStack Query • Vite build toolchain • Turborepo monorepo (or willingness to ramp quickly) • Experience with testing frameworks (Vitest, Playwright) • Comfortable working on SDK-based architectures — versioning, publishing, consumer-facing APIs, breaking changes, graceful fallbacks • Strong understanding of performance optimization (Core Web Vitals, lazy loading, bundle analysis) PLATFORM & MOBILE (CORE TO THIS ROLE) • Hands-on exposure to React Native, Flutter, or mobile WebViews • Understanding of WebView / native bridges and cross-platform constraints • Interest in building and maintaining SDKs across web + mobile ecosystems PRODUCT & DOMAIN • Security-aware: comfortable working on payments and KYC flows where correctness, data handling, and cross-origin safety matter. Treats PII, tokens, and postMessage origins with appropriate care. • Product sense: pushes back on briefs when the UX is wrong; distinguishes "technically correct" from "right for the user" NICE TO HAVE • Design systems (Storybook, component libraries) • Backend basics (REST, GraphQL, Node.js) • DevOps exposure (CI/CD, AWS, Docker) • Prior fintech, payments, or compliance product experience HOW WE WORK We're a small, high-ownership team where engineers: • Own features end-to-end — not just tickets • Ship fast, but with a strong focus on quality • Work directly with founders and leadership • Build systems that are used in real production environments WHAT WE VALUE • Ownership: takes initiative and drives outcomes • Frontend Craft: cares deeply about performance, UX, and quality • Pragmatism: balances speed with long-term scalability • Curiosity: open to learning mobile and platform systems • Honesty: clear about what they know and where they're growing WHY THIS ROLE This is a high-impact role for engineers who want to: • Build fintech products at scale (payments, KYC, compliance) • Work across frontend + mobile + platform layers • Have real ownership and influence on architecture • Be part of a long-term, high-growth journey
