• Have experience with observability tooling such as Prometheus and Grafana or similar. • Have comfort with Redis for distributed state and queue management. • Have experience with distributed job scheduling or work queue systems understanding the failure modes and edge cases. • Have experience operating systems where correctness and data quality are the primary constraints.

• Embed within the Search team to ensure index improvements translate into better results for users. • Design and improve the URL frontier and crawl job scheduling system deciding what to index, when, and in what order. • Own and evolve the indexing strategy and ranking implementation. • Investigate and fix index quality issues including spam, stale content, deduplication, and coverage gaps.
