Full job description
Lead the Identity squad on the Data Platform team to develop and scale identity resolution algorithms and pipelines at US scale. Responsibilities include setting technical direction, designing clustering algorithms, optimizing distributed compute and storage (Dagster, Spark, Iceberg), improving identity resolution accuracy, and managing infrastructure costs. The role involves technical leadership, hands-on algorithm development, and team mentorship. Requires 8+ years experience in production ML or data systems, expertise in entity resolution and clustering, strong distributed systems knowledge, and excellent cross-functional communication. Benefits include variable pay, hybrid work in Paris, health insurance, meal vouchers, annual offsite, and quarterly tech syncs. Salary range for France-based candidates is €127,000-€171,000.
