Manila, National Capital Region, Philippines SellerX Full time
Overview

Senior Front-End Engineer (x/f/m) role at SellerX. You'll own the SellerX Portal, our core internal platform used by operations, finance, supply chain, and commercial teams. This is not a consumer-facing product; you'll shape the systems our teams use daily to make high-quality, data-driven decisions — fast. You'll lead the evolution of the front-end architecture, own critical UI experiences, and collaborate across functions to bring scalable, reliable tools to life. This is a 12-month contract role, with the possibility of extension based on project needs and performance.

In This Hands-on Role, You Will
  • Architect and evolve the front-end of the SellerX Portal, built in React
  • Build modular, reusable components for high-performance internal tools
  • Translate UX and product specs into polished, responsive, accessible UIs
  • Collaborate closely with product, design, and backend engineers on cross-functional features
  • Optimize performance and reliability for complex UI workflows
  • Contribute to test automation, CI/CD pipelines, and system observability
  • Occasionally dip into Python backend code to support seamless end-to-end delivery
What You'll Need To Thrive
  • 4+ years of front-end experience with deep expertise in React and modern JavaScript (ES6+)
  • Strong architectural thinking and understanding of component design patterns
  • Experience building interfaces for complex internal tools or platforms
  • Familiarity with state management, build tools (Vite, Yarn), and Git workflows
  • Proficiency in writing clean, testable code (e.g. with Cypress, Playwright, or Selenium)
  • Ability to collaborate across disciplines and align tech solutions to business needs
  • Clear communication and a strong product mindset
Bonus Points For
  • Experience with micro frontend or service-based frontend architectures
  • Contributions to design systems or large component libraries
  • Familiarity with Docker, performance profiling, or CI/CD setup for front-end projects
  • Previous work in e-commerce, logistics, or internal operations tooling
  • Passion for improving developer experience and shaping engineering best practices

This is a 12-month contract role, with the possibility of extension based on project needs and performance. Join us and be part of building scalable tools that make a real operational impact.
