What the job involves
- ZoomInfo is seeking a Senior Data Scientist to join our Data Science team to develop AI models that power our industry-leading B2B sales and marketing intelligence platform. If you are a visionary data scientist with expertise in Recommender Systems, Language Understanding, and Semantic Search, this is an exciting opportunity to shape how businesses identify and act on the most valuable market signals

- Develop and optimize recommender systems that suggest the most impactful signals, actions, and contacts to our users
- Leverage Large Language Models (LLMs) to enhance entity recognition, relationship mapping, and trend detection from unstructured text, including news articles, emails, call transcripts, and customer interactions
- Build scalable ML pipelines to process and score signals in real time, ensuring high performance and accuracy in production
- Collaborate with ML engineers to deploy models using cloud infrastructures and distributed computing frameworks (Spark, Ray, etc.)
- Continuously evaluate and refine models based on user feedback, A/B testing, and real-world performance metrics
- Stay ahead of the latest research in recommender systems, GenAI, and AI-driven scoring models, ensuring our solutions remain cutting-edge and industry-leading
Our take
It was only a few years ago when B2B sales teams relied on warm introductions and contact books. Now, cloud-based CRM, automation and Big Data are critical tools for any selling process. ZoomInfo’s B2B contact base has played a massive part in that journey.
The company primarily helps salespeople find potential customers. Crucially, ZoomInfo then leverages technology to help make that approach as successful as possible. Think contact details of the most likely budget holder at that company, signal for when and how to approach and crucial updates on the company’s fortunes.
ZoomInfo has grown significantly over the previous few years and is now shifting its approach to pursue more inorganic growth through mergers and acquisitions, acquiring several companies in 2022, including the job recruitment website Comparably.
The risk for ZoomInfo is that these moves represent expansion beyond its traditional strengths in top-of-funnel customer acquisition. The company will need to ensure that it maximizes synergies in order to win in these markets. The company has expanded operations in India and is set to see further expansion, as indicated by its appearance on the Fortune Future 50 list of robust and growing companies in 2023.
