Join Reach at Smartly to build an analytical product that helps customers understand brand marketing performance and make better investment decisions.

The work spans interactive interfaces, backend services, data processing, and statistical models. Challenges include deterministic deduplication and frequency distribution estimation: problems where assumptions, edge cases, and validation matter.
