Software Development Engineer

The Device Ad Products team is hiring Software Development Engineers to help scale and evolve our ad platform for Amazon-owned devices like Fire Tablets, Alexa Tablets, and Echo Show. We’re a lean team with startup energy, backed by Amazon’s infrastructure and resources—giving you the freedom to move fast and the support to build at scale. What You’ll Do You’ll be part of the core engineering team responsible for the systems that power ad delivery, performance optimization, and reporting across devices. These systems process hundreds of millions of events per day, and your work will directly impact latency, data quality, and platform reliability. You’ll design, build, and operate services that: * Optimize ad delivery in real time using data-driven logic (and increasingly, ML/AI models). * Scale backend pipelines to handle high-throughput event ingestion and processing. * Provide accurate and low-latency reporting to advertisers. * Support experimentation and measurement at scale. There are opportunities to work on systems for real-time bidding, targeting, and ad ranking—especially as we explore smarter optimizations for ad placement on-device. Why This Role * Tangible Impact: Your work affects ad experience and monetization across Amazon devices. * Scalable Challenges: Work on high-volume systems where performance and reliability are critical. * Tech Stack Variety: Exposure to AWS services, stream processing frameworks, and multiple programming languages (Java, Kotlin, Python, etc.). * AI Opportunity: Help shape how we apply machine learning and AI to improve targeting, delivery, and measurement. This isn’t a team that throws work over the wall. You’ll be involved from design to deployment—and have a voice in what we build next. If you’re pragmatic, data-driven, and energized by complex distributed systems—and you're curious about how AI can be embedded into production software—we’d love to talk.
