Internship Amazon Work Jobs (NOW HIRING)

Are you excited about building systems that power personalized experiences for hundreds of millions of Amazon customers? Customer360 is Amazon's central customer memory system that standardizes behavioral and profile data from across Stores, Prime Video, Music, Kindle, Audible, Alexa, and other Amazon surfaces. We serve these memories at scale to customer all across amazon's businesses, enabling any team or AI agent at Amazon to understand a customer without independently integrating with dozens of data sources.
We're looking for a Software Development Engineer to help us scale C360 as we continue to grow and better understand Amazons customers. We are building contextual retrieval capabilities using embedding-based semantic search, connecting Amazon's different businesses together, and scaling our platform to support all of Amazon in delighting our customers.
Key job responsibilities
Design, build, and operate low-latency, high-throughput distributed systems serving real-time customer data at Amazon scale
Develop and extend the C360 read APIs, including contextual retrieval features powered by embedding-based semantic search
Own the full lifecycle of features from design through deployment worldwide
Collaborate with 100+ partner teams across Amazon to onboard new customer datatypes and enable personalization use cases
Participate in operational excellence for a Tier 1 service, including on-call rotations, alarm tuning, and incident response
Contribute to the architecture of our hot layer (sub-second freshness, in-memory cache, 28-day retention) and icy layer (batch, permanent storage) data systems
A day in the life
You might start your morning triaging a request from the Alexa team who needs us to help claw back latency for a launch next month. You dig into the schema, work through the retrieval strategy with your team, and draft a short design doc. After lunch, you pick up a code review from a teammate who's optimizing how we serve filtered reads for a high-TPS Prime Video use case. In the afternoon, you're on a call with a producer team onboarding their first dataset. You walk them through our APIs, helping them validate their data in our beta environment, and making sure they're set up for a smooth launch. Before wrapping up, you push a quick fix for an alarm that's been noisy and update the runbook so the next on-call has better context.
About the team
Customer360 ReadService (C360RS) is the real-time read layer of Amazon's central customer memory system. We're a team within Amazon Personalization that builds and operates the APIs partner teams across Amazon rely on to understand their customers. When Alexa needs to know a customer's brand preferences, when Prime Video wants to personalize recommendations based on recent purchases, or when Rufus needs to recall that a customer has a bicycle in need of a new seat, they call us. We're a high-ownership team running a highly scaled Tier 1 service across all of Amazon's marketplaces. We take pride in making customer data fast, reliable, and easy to consume. We value operational excellence, pragmatic engineering, and a collaborative culture where everyone has a direct line to the decisions that shape the platform.
