Hightouch is hiring a Head of Machine Learning to lead ML across its Composable CDP and agentic marketing platform. Hundreds of companies use Hightouch to sync warehouse data into their SaaS tools, and this role builds the intelligence layer on top: deciding which customers to message, what content to send, and when. It is both a people-leadership and hands-on technical role, owning roadmap, recruiting, reliability and team growth. The problem space is concrete: personalization and product recommendation over large catalogues, probabilistic identity resolution across messy customer datasets, LLM-driven content generation, and the ML infrastructure to train and serve models at enterprise scale. Given Hightouch's direct access to customer data warehouses, the company is unusually well positioned to build this. The role is pitched as senior but weighs impact and growth potential over raw years, with a wide $230K to $350K band reflecting that.
