• You help design and optimize notification pipelines (app push, e-mail, etc.) to make sure messages are timely, relevant, and valuable to users.

• You improve our price-based features (e.g., price history, alerts, and insights) by enhancing performance, data quality, and user experience.

• You collaborate closely with Product, Data, App, and Web teams, conduct experiments/ A-B tests, and use data to make informed decisions that improve user engagement.

• You contribute to our architecture, observability (monitoring and alerting), and CI/CD setup, with services running on AWS in a continuous delivery environment.
