We're hiring a Senior Data Scientist to lead a workstream within Caremark's sales and underwriting analytics portfolio - owning end-to-end delivery as a senior individual contributor, setting technical direction, and mentoring peers. Workstreams span pricing and risk modeling, portfolio and strategy analytics, and the reporting and insight products our business runs on.
