About The Team And The Role

Join eBay’s Ads Platform team, the engine behind our growing suite of advertising products. We build the core infrastructure that powers all ad delivery across eBay — from Promoted Listings to Promoted Stores and third-party ads. Our platform is foundational to eBay’s strategic priority of accelerating ads-driven growth, helping millions of sellers drive visibility and sales.

We’re hiring a Full Stack Engineer to help scale and evolve this high-impact platform. You’ll contribute to the real-time ad server, campaign management systems, attribution pipelines, and infrastructure for emerging products like Promoted Stores — which showcases eBay storefronts in rich, branded ad placements.

In this role, you’ll report to a Senior Engineering Manager in the Ads org and work cross-functionally with product, data, and other platform teams. This is an opportunity to help shape the future of eBay advertising while solving technically complex, large-scale backend and frontend challenges.

What you will accomplish

• Build high-performance, distributed systems that serve billions of real-time ad impressions with low latency and high reliability
• Contribute to core ad infrastructure including our ad server, campaign manager, tracking pipelines, and publisher integrations
• Help scale Promoted Stores, one of eBay’s fastest-growing ad products, delivering impactful storefront experiences for sellers
• Collaborate across Ads, Product, and Platform teams to deliver features that connect buyers and sellers in meaningful ways
• Practice and advocate for clean, maintainable code, including adoption of functional programming concepts in Scala
• Grow your skills in large-scale systems, ad tech, observability, and frontend technologies through hands-on development and mentorship opportunities
  
  
  

What you will bring

• 4+ years of software development experience with strong computer science fundamentals
• Proficiency in Java and/or Scala (or a willingness to learn Scala); experience with functional libraries like Cats, ZIO, or Monix is a plus
• Experience building and maintaining backend services in a distributed systems environment; knowledge of Spring Framework and REST APIs
• Full stack capabilities including modern JavaScript (React), HTML/CSS, and Node.js
• Familiarity with databases (e.g., MySQL, Postgres, MongoDB) and streaming/messaging technologies (e.g., Kafka, Flink, RabbitMQ)
• A collaborative mindset and enthusiasm for agile development, code quality, and solving tough problems that deliver real business impact
