Senior Machine Learning Engineer, GTM Data

HubSpot’s mission is to Help Millions of Companies Grow Better, and we believe recent advances in AI/ML will allow our internal Go-to-Market (GTM) teams to more effectively serve even more companies, helping them to grow. We’re seeking a talented Senior Machine Learning (ML) Engineer to join our GTM Data and Systems team as part of a newly-formed GTM AI team supporting our internal Sales and Customer Success (CS) clients through the delivery of scalable AI/ML and other data products to improve the efficiency and efficacy of frontline Sales and Customer Success reps and solve for their pain points.
