Senior Data Scientist Information Retrieval & NLP
to help build and scale transformative machine learning systems. You'll be responsible for leading projects in neural search (RAG, transformers), named-entity recognition (NER), and large-scale entity resolution that touch billions of records and power millions of daily queries. This is a highly strategic role with deep technical ownership, strong cross-functional visibility, and tangible business impact. What Youll Do: Information Retrieval (IR): Design and deploy Transformer/RAG architectures to optimize the search and retrieval of contact, company, and business insights. Implement quantization, distillation, and fine-tuning to ensure low-latency, cost-effective model performance at petabyte scale. Build hybrid dense/sparse retrieval pipelines using vector databases like Pinecone, Weaviate, FAISS, or OpenSearch. NER & Entity Resolution: Develop high-accuracy NER models that tag people, organizations, and geo/industry entities across multi-language content. Build real-time, large-scale entity resolution systems that deduplicate and link hundreds of millions of records, using knowledge-graph signals where applicable. Design large-scale A/B tests and back-testing plans to validate models and drive KPIs. Translate product objectives into measurable ML outcomes, influencing roadmaps and capacity planning. Cross-Team Collaboration & Thought Leadership: Mentor junior engineers and scientists, write internal documentation, and contribute to external publications or conference presentations. Collaborate with stakeholders across engineering, product, and leadership to align ML efforts with business strategy. What You Bring: Experience:
7+ years in ML/NLP (or 4+ years post-Masters/PhD), with at least two successful product launches that delivered business value. Technical Skills: Deep knowledge of Transformer models (BERT, GPT, T5), RAG, and vector-based IR. Proven success in NER and entity-resolution at 100M+ scale. Experience with knowledge graphs is a plus. Strong programming in Python and ML frameworks (PyTorch or TensorFlow); Go/Java a plus. Familiarity with MLOps tools (Docker, Kubernetes, Terraform, GitOps, feature stores, model registries). Communication:
Comfortable presenting findings to executive and non-technical audiences; able to drive strategy and investment conversations. Whats In It For You: Salary Range:
$167,760 $230,670 USD base + potential bonus, equity, and benefits. Work Environment:
Hybrid model based in Waltham, MA. Comprehensive Benefits:
Medical, dental, vision, mental health support, lifestyle perks, and holistic wellness programs. Career Growth:
Work on high-impact AI systems in a world-class applied science team with ample opportunity for advancement and visibility. Apply Now: If you're a passionate data scientist ready to build scalable, real-world AI solutions that move the needle, ZoomInfo wants to hear from you. Click
