We move fast, think boldly, and empower you to do the best work of your life. You'll lead the team that builds the intelligence every ZoomInfo AI agent reasons over , what's true about companies and the people in them, how they relate, and what they're buying. This role owns the B2B data graph strategy end to end, from training data through model serving, blending classical machine learning and data science with LLM and agentic systems. **Responsibilities** - Extend ZoomInfo's B2B data graph into the long tail, making it the most comprehensive and accurate resource available, including companies with little public footprint. - Lead the team's work on agent memory, distinguishing what a user has supplied from what a system of record already owns. - Choose the right method for each problem , classical machine learning, language models, or code , based on measured evidence, and stop work that won't pay off. - Define the evaluation bar for the team's models and agents, building evaluation datasets, regression gates, and experiment designs that make quality claims trustworthy. - Own inference cost, latency, and capacity as core disciplines alongside model quality, including build-versus-buy and distillation decisions. - Hire and develop machine learning engineers, data scientists, and research engineers, growing senior engineers into technical leaders. - Represent the team's work across product, platform, security, and legal, and present results and their limits clearly to executives. - Set the standard for how the team uses agentic coding tools, pairing precise specifications with rigorous code review. **Requirements** - Significant, demonstrated experience building and shipping production machine learning systems, and leading by building alongside your team. - Track record of hiring and developing senior machine learning engineers and data scientists against a high bar. - Hands-on experience: shipping code, prototyping independently, and using agentic coding tools daily with rigorous review. - Deep classical machine learning and data science expertise (supervised learning, feature engineering, statistical inference, experiment design, strong SQL) alongside production LLM and agentic systems. - Experience owning inference cost, latency, and capacity alongside model quality, including build-versus-buy decisions. **Preferred Qualifications** - Entrepreneurial experience , founding a company, or taking a product from inception to paying customers as a founding or early engineer. - Experience in propensity modeling, ranking and retrieval, clustering, or entity resolution at scale. - Experience with web-scale language processing over multilingual, noisy text, knowledge graphs, or user memory for agents. - Experience with post-training and distillation, open-weight model serving, or AI governance and safety practices. **Benefits** We offer comprehensive benefits and holistic mind, body, and lifestyle programs designed for overall well-being. ## Skills ### Required - machine learning - data science - classical machine learning - LLM - agentic systems - SQL - feature engineering - statistical inference - experiment design ### Nice to have - propensity modeling - ranking and retrieval - clustering - entity resolution - web-scale language processing - post-training and distillation - open-weight model serving - AI governance and safety practices --- Source: [Apply at job-boards.greenhouse.io](https://job-boards.greenhouse.io/zoominfo/jobs/8800796002?utm_source=yubhub.co&utm_medium=jobs_feed&utm_campaign=apply)
