Senior Software Engineer, Offsite Ads

About The Role

The Ad Supply team is the engine of Consumer Experience for Uber's Offsite Ads business. We are responsible for expanding Uber's advertising reach beyond our native apps, creating intentful sessions for users across the open web. As a Senior Software Engineer, you will enable how Uber's premium ad formats are dynamically rendered and integrated into external environments. This isn't about maintaining legacy systems. You are building the foundational supply layer for a brand-new business vertical at Uber.

This is a high-impact, full-stack role where you will bridge the gap between Uber's internal ad-serving infrastructure and the vast ecosystem of third-party channels. You will architect the systems that deliver "shoppable" and intent-driven ad experiences, ensuring they are as seamless and performant on an external site as they are within the Uber app.

What You'll Do

• Expand Reach: Build and maintain the technical infrastructure required for channel expansion, enabling Uber Ads to launch on new external surfaces rapidly.
• Optimize Consumer UX: Implement onsite UX improvements and "shoppable" features that turn a simple ad click into a high-intent user session.
• Deliver High-Quality Code: Act as a primary contributor to our offsite web SDK and supply-side backend services, ensuring high reliability and sub-100ms response times.
• Collaborate Across Pods: Work with the Ad Delivery pod to ensure identity matching is seamless and with the Tooling pod to surface reporting data.
• Mentor Junior Talent: Help grow the team by providing thoughtful code reviews and assisting in the onboarding of new engineers.
  
  

Basic Qualifications

• Experience: 5+ years of professional software development experience, with a strong focus on high-traffic web applications.
• Full Stack Capabilities: Deep proficiency in React, TypeScript, and Node.js. You should be comfortable managing complex state and building reusable UI libraries.
• Backend Fundamentals: Strong experience in Go or Java, particularly in building REST or gRPC microservices that handle high-concurrency workloads.
• Web Performance: Solid understanding of browser rendering, asset optimization, and how to minimize latency in third-party environments.
• Technical Ownership: Proven ability to lead feature development from ideation through deployment, including writing design docs and performing code reviews.
  
  

Preferred Qualifications

• Ad-Tech Product Experience: Practical experience building consumer ad products from end-to-end, or building "native" ad formats.
• SDK Development: Experience building third-party libraries or widgets meant to be consumed by other developers.
• Testing & Observability: Expertise in setting up robust monitoring (e.g., Prometheus, Grafana) and automated testing suites for distributed systems.
• API Design: Experience designing clean, extensible APIs that serve both internal and external stakeholders.
