At Uber, Frontend Engineers build web experiences that power the way people move and receive things around the world. As part of our engineering team, you’ll work on large-scale applications that impact millions of users. You’ll collaborate with cross-functional partners (design, backend, data science, product). Your work will help shape the future of Uber’s Delivery, defining how people interact with Uber on the web.

Job Responsibility

  • Design and implement user-facing features for critical web properties at scale, making engineering trade-offs between speed, maintainability, and user experience
  • Own the technical design and execution of features, from initial architecture discussions to debugging production issues
  • Collaborate across disciplines, Product, Design, Data Science, and Backend Engineering, to turn ambiguous business needs into clear, scalable front-end systems
  • Champion front-end engineering excellence, defining and leading the adoption of code health, testing, and design standards within your project area
  • Improve core application performance, efficiency, and system reliability, proactively identifying and tackling areas of technical debt in software and processes within your team
  • Mentor junior and mid-level engineers on best practices, system design philosophy, and navigating cross-functional project dynamics

Requirements

  • 7 years of professional software engineering experience, with a focus on large-scale, high-traffic web applications
  • Hands-on experience and proficiency in a modern web framework such as JavaScript, React, VueJS, or Angular, plus HTML and CSS
  • Proficiency in fundamental algorithms and data structures, including hash tables, trees, stacks, queues, linked lists, DFS, and BFS
  • Demonstrated understanding of modern web application architecture and design patterns, and their implications for performance and scalability
  • Advanced English communication skills, written and verbal, to effectively collaborate with globally distributed cross-functional teams

Nice to have

  • Experience leading the technical direction of complex, cross-functional projects with multiple dependencies
  • Familiarity with back-end systems (e.g., Go, Python, TypeScript) to facilitate collaboration and diagnose full-stack issues
  • Experience with the full project lifecycle, from idea inception and stakeholder engagement to monitoring in production
