Senior Frontend Developer

Working location: Gia Dinh Ward (Binh Thanh District),Ho Chi Minh City

Salary range: Up to VND 75,000,000 gross

INFORMATION

This is a new, cloud-native multi-shop SaaS platform: headless, API-first, built on Microsoft Azure, and closely integrated with the ERP Cloud as the leading cloud ERP system. The goal is a scalable, economically operable platform that lets growth-oriented merchants run multiple shops, brands, and markets from a single backend. To build this platform – from architecture through MVP launch – they are assembling a new, interdisciplinary project team. As a Senior Frontend Developer, you define the frontend architecture of the new, headless platform and build a scalable, reusable component system for a multi-shop frontend. You ensure the storefront's performance, SEO, and accessibility, and integrate the frontend closely with the backend APIs. This role is part of the interdisciplinary project team (Tech Lead, Product Owner/Project Manager, UI/UX, Frontend, Backend, DevOps, QA) and works in short, agile cycles with clear definition-of- done and review processes.

RESPONSIBILITIES

Define the frontend architecture of the new, headless platform, including rendering strategy (SSR/ISR) and routing.

Build scalable component systems and a reusable UI architecture for a multi-shop/multi-tenant frontend.

Ensure the storefront's performance (Core Web Vitals), SEO, and accessibility.

Integrate the frontend closely with the backend APIs and data flows from the ERP Cloud and other platform services.

Conduct code reviews and define binding standards for frontend development across the team.

Work closely with UI/UX design to implement design systems cleanly.

REQUIREMENTS

Several years of experience (typically 5+ years) as a frontend developer, including proven experience in a senior role.

Strong knowledge of Next.js (SSR, ISR, routing, middleware) and React (advanced patterns, hooks, state management).

Experience in SEO optimization (metadata, structured data) and performance optimization (Core Web Vitals).

Experience building component libraries or design systems for scalable frontends.

Confident handling of REST APIs and modern data-fetching strategies, e.g. caching, ISR, streaming.

Understanding of headless/PWA architectures in an e-commerce context.

Personal competencies.

High quality standards for code, performance, and user experience.

Independent, structured way of working.

Enjoys technical discussion and constructive feedback within the team.

A big plus:

Experience with multi-shop/multi-tenant frontends (theming, internationalization, locale/currency handling).

Knowledge of accessibility standards (WCAG).

Experience working closely with UI/UX teams, e.g. via Figma handoff.

Experience with AI-assisted development tools (Claude Code, GitHub Copilot) in daily work.
