• Maintain server-side integrations with advertising platforms, including reliable event delivery, deduplication, retries, and monitoring.
• Track attribution across the visitor journey, preserve campaign parameters, and investigate gaps in conversion data.
• Improve service performance and reliability through caching, query optimization, and production debugging; investigate issues in the Node.js/Express rendering layer as needed.

Requirements

• At least five years of production backend development in Python, including designing, shipping, and supporting services.
• Strong experience with API design, relational databases and SQL, caching, background jobs, and third-party integrations; understand authentication, rate limits, retries, and idempotency.
• Able to investigate production problems using logs and error tracking and identify root causes.
• Comfortable reading and modifying Node.js and Express services.
• Working knowledge of React and TypeScript sufficient to deliver features end to end.
