About the Job/Responsibilities

The team is composed of multiple squads: the platform squad along with cross-functional squads that leverage the platform to develop products. As a senior engineer on our platform squad, you will work on a team of 4+ engineers and optimize experimentation, development, and production operations for our ML and AI-powered experiences. You will build and maintain pipelines and APIs, provide developer tooling, and partner on integrations.

Here are some of the key challenges our team will tackle this year:

• Optimize Site Performance:

Dynamically deliver personalized content alongside cached assets, improving load times and enhancing user experience with features like page-level deduplication

• Enhance Data Access:

Continue to evolve our pipelines to ensure the timeliest access to instrumentation and content data for feature and model development

• Accelerate Experimentation:

Partner with our Data & Analytics organization to improve the tooling and coordination involved in A/B testing

• Support Engineering with Foundational Models:

As tools like Bedrock emerge, enhance our platform to support them, ensuring we’re prepared for the next generation of AI-powered applications

Here are some of the things you can expect to do on a day-to-day basis:

• Work closely with ML engineering to make data easily accessible and understandable
• Ensure the reliability and minimize the latency of data delivery for ML use cases
• Create transparency in our data pipelines with comprehensive telemetry
• Develop and enforce data engineering, security, data quality standards through automation
• Collaborate with other engineers to develop and enhance core capabilities, infrastructure, and architecture
• Leverage vended and open-source cloud technologies to reduce maintenance costs and improve efficiencies, ensuring our products remain profitable
