This is a combined, senior role. You'll own a 10-person and growing data engineering team and a 3-person (and growing) AI group, with a mandate to make them work as one integrated capability.The opportunity: we have rich, structured insurance data composed of underwriting submissions, loss runs, pricing signals, claims history.
