You will own your work end-to-end, from understanding the problem to deploying and operating production systems, while helping shape the technical direction of a product that marketing teams across Amazon will rely on., * Design and build data ingestion pipelines and APIs that collect, normalize, and unify marketing data from dozens of external agencies, vendors, and platforms. * Develop services that prepare clean, structured data for consumption by AI agents, enabling plain-language analytics for marketing teams across Amazon. * Identify and resolve root causes of operational issues, driving permanent fixes and continuously improving system reliability and data quality. * Mentor and coach other engineers through code reviews and design discussions, helping establish best practices as the team grows. * Collaborate with product, data science, and marketing stakeholders to translate business needs into well-scoped technical solutions using big data technologies such as Spark and Hadoop. A day in the life You might start your morning reviewing a teammate's pull request for a new data connector, then shift into designing the schema changes needed to onboard a new vendor feed. After lunch you dig into a data-quality anomaly, trace it back to an upstream format change, and ship a fix along with an automated check to catch similar issues in the future. Because this is a new team building from scratch, you will also have a hand in choosing frameworks, setting coding standards, and shaping the architecture that everything else is built on. ## Related Videos - [PySpark - Combining Machine Learning & Big Data](https://www.wearedevelopers.com/videos/44-pyspark-combining-machine-learning-big-data) - [Alibaba Big Data and Machine Learning Technology](https://www.wearedevelopers.com/videos/37-alibaba-big-data-and-machine-learning-technology) - [Fireside Chat with Werner Vogels, VP & CTO, Amazon.com & Daniel Gebler, CTO at Picnic](https://www.wearedevelopers.com/videos/1405-fireside-chat-with-werner-vogels-vp-cto-amazon-com-daniel-gebler-cto-at-picnic) - [Are Code Reviews Worth It?
