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).
About the Teams
Delivery:
The Delivery team is focused on innovating and streamlining how products and services reach our customers. In this role, you'll contribute to building efficient and robust systems that support order processing, logistics, and real-time tracking. Your contributions will help optimize the end-to-end delivery experience, making it more reliable and seamless for both drivers and customers.
ADS:
The Ads team builds and scales the advertising platform and its features that power sponsored experiences across Uber’s apps, connecting riders, eaters, and advertisers in relevant and measurable ways. The team owns end-to-end ad delivery (from ad creation, rendering, and experimentation to tracking, measurement, and performance optimization) across mobile and web surfaces. The work sits at the intersection of product, platform, and data, ensuring ads are high-quality for users while driving impact for advertisers and Uber’s business.
Mobility (Rider Core):
Millions of people depend on Uber’s web application to make ride reservations and get on-demand Uber rides. The Rider Core Team at Uber is redefining what it means to Uber and expanding our products beyond on-demand rides. In this role, you'll work with many distributed teams, ranging from designers, engineers, and data scientists, to provide market-defining products and trip planning experiences over the web.
What You’ll Do
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.
What You’ll Need
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.
Bonus Points If
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.
