About Us
Hello Clever is building the next generation of payments and loyalty infrastructure by turning every transaction into growth for merchants.
We're an AI-powered fintech operating across 26+ markets, helping businesses move money in real time and convert payments into measurable outcomes like higher repeat rates, bigger baskets, and smarter customer engagement. Our platform combines local account-to-account rails, embedded cashback and loyalty products, and powerful data intelligence through Clever AI, so merchants can launch offers, optimise ROI, and scale faster, all through a single integration.
We recently crossed $70M in live ARR and are on track to pass $100M by the end of 2026-just 2.3 years after reaching our first $1M. It's an exciting milestone that reflects the scale of what we're building and the opportunity ahead.
We're also proud to be recognised on the global stage, including being named Australia's fastest-growing fintech, recognised in Forbes Asia's Top 100, ranked among the AFR Fastest-Growing Companies, and selected for Inc. Magazine's Best in Business.
Role Focus
This is a Mid/Senior Frontend Engineering role focused on building and evolving production-grade React web applications, with React and TypeScript as the core technologies. You will own frontend architecture and help shape engineering standards across the products you work on.
This is a full-time, hybrid role based in Ho Chi Minh City, with occasional in-person catch-ups at our office and no fixed office days. You will work Vietnam business hours, with availability to join regular meetings with our US team outside those hours.
Responsibilities
Design, build, and maintain accessible, responsive React experiences across our payment, merchant, dynamic checkout and internal operations products.
Own frontend architecture across the codebase, including application structure, state management, data flow, component boundaries, API integration, and dependencies. Surface architectural, performance, and reliability risks early.
Establish reusable patterns, shared components, and engineering standards across products and teams.
Act as the technical point of contact for frontend decisions with US-based stakeholders, and raise the quality bar through code review, pairing, and guidance.
Implement complex flows involving payments, multi-currency experiences, asynchronous states, retries, failures, validations, and edge cases.
Improve performance, reliability, accessibility, security, and maintainability across the frontend codebase.
Investigate production issues, support root-cause analysis, and help prevent recurring problems.
Requirements (Must Have)
3+ years of frontend engineering experience, with proven ownership of production-grade React applications shipped end to end.
Strong hands-on experience with React and TypeScript, plus solid fundamentals in JavaScript, HTML, CSS, browser APIs, responsive layouts, and accessibility.
Strong understanding of frontend architecture, covering component design, state management, data flow, API integration, and application structure, with the judgment to balance trade-offs and evolve existing systems without unnecessary complexity.
Experience acting as a technical anchor on a team: driving architecture decisions, establishing reusable patterns and standards, and lifting code quality through review and guidance.
Experience integrating with REST APIs, strong debugging skills using browser DevTools and performance tooling, and a good understanding of unit, integration, and end-to-end testing.
Clear written and verbal English communication, with the ability to work independently across distributed teams.
Nice to Have
Experience with [protected info] or similar ReactJS frameworks.
Experience building or maintaining design systems and reusable component libraries.
Payment, fintech, banking, marketplace, or e-commerce experience, including PCI-aware frontend practices.
Experience with Playwright, Cypress, Jest, React Testing Library, or similar testing tools.
Experience with React Native or mobile-first product development.
A disciplined approach to AI-assisted development, using tools like Cursor, Claude Code, or GitHub Copilot without letting review standards slip.
