Role

Who you are

7+ yrs hands-on ML/NLP experience (or 4+ yrs post-PhD/Master’s) with at least two delivered, revenue-impacting products
Expertise in transformer stacks (BERT/GPT/T5), RAG, vector-based IR, and latency/throughput optimization
Proven track record building NER or entity-resolution systems at 100M+ record scale; knowledge-graph experience is a plus
Strong applied research chops (PyTorch or TensorFlow) paired with software-engineering rigor (Python, Go/Java a plus)
Desire to work within MLOps tools and frameworks: Docker, K8s, GitOps, Terraform, feature stores, model registries, automated retraining
Ability to persuade exec and non-tech audiences with data-driven storytelling; comfortable owning strategy & budget

What the job involves

Invent and productionize Transformer/RAG architectures that surface the right contact, company, or insight
Drive quantization, distillation, and SLM fine-tuning so models stay fast and affordable at petabyte scale
Prototype and launch hybrid dense/sparse retrieval pipelines on vector DBs (Pinecone, Weaviate, FAISS, OpenSearch)
Own high-recall NER models that tag people, orgs, locations, and industry-specific entities across multi-language text
Build cross-dataset entity-resolution frameworks that dedupe hundreds of millions of records with sub-second latency; enrich with knowledge-graph signals where valuable
Design large-scale A/B and back-testing plans; close the loop from experiment to KPI uplift
Translate product goals into measurable ML KPIs; influence roadmap, capacity, and investment decisions
Mentor junior scientists/engineers; publish internal requirements documents, external blogs, and present at conferences

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.
