Job description

About the Role

SellAbroad is building the world’s leading cross-border commerce infrastructure — powering localized checkouts, global payments, duties/tax automation, AI-driven storefront localization, and 2-day international delivery.

We are looking for a Frontend Engineer who can build reliable, high-quality commerce experiences that help brands sell worldwide. You will work on technology that directly impacts merchant revenue and cross-border expansion — not generic dashboards or brochureware.

Minimum Requirements

• 3+ years building production-grade frontend applications

• Strong practical experience with React + Next.js (App Router) — SSR, server/client components, routing

• Experience with transactional UI or checkout/payment-related workflows

• Familiarity with browser behavior inside embedded webviews (e.g. Shopify, Meta) or willingness to learn

• Ability to communicate clearly and work efficiently across product/design/engineering

Technical Skills

Core Frontend

Solid proficiency in:

• React + Next.js

• TypeScript

• TailwindCSS

• shadcn/ui & Radix UI

• Framer Motion (optional but useful)

Plus familiarity with:

• Zustand / TanStack Query / Context for state management

• Basic frontend performance concepts

• Composable UI + reusable component patterns

Payments & Checkout

Helpful experience in:

• Stripe or similar payment providers

• Handling checkout UX edge cases (loading states, retries, validation, 3DS, etc.)

• Understanding high-level webhook flows (backend-owned, but frontend must align)

• Debugging networking and client-side logs

Experience with BNPL, UPI, or other regional methods is a plus, not required.

SellAbroad-Specific Stack Knowledge (Preferred)

You should be comfortable with or willing to quickly learn:

• Next.js checkout & storefront localization

• React + Tailwind + shadcn/ui

• Payment Intent–based card flows (Stripe)

• Multi-currency & multi-language switching

• IP-based geo-personalization

Shopify exposure is useful:

• Theme editing (Liquid + JS injection)

• Shopify Markets concepts (currencies, domains, languages)

• Working inside Shopify’s in-app browser/webviews

Experience with OMS-style dashboards (orders, payouts, tracking) is a bonus.

Responsibilities

• Build localized checkout and storefront experiences for global markets

• Implement clean, reliable payment UIs that increase conversion

• Work with backend/product to deliver merchant-facing features rapidly

• Debug issues across browser, webviews, networking, and performance

• Maintain code quality via linting, formatting, and CI/CD best practices

Soft Skills

• Strong problem-solving abilities with emerging ownership skills

• Communicates clearly and proactively during development

• Works well in fast-paced iteration cycles

• Curious, product-minded, and eager to learn deeper commerce concepts

• Comfortable switching between implementation and debugging mode
