What you'll do

  • Build and evaluate ML approaches for company/entity matching.
  • Develop embedding and LLM-based matching approaches.
  • Develop scoring and ranking methodologies to identify true matches and distinguish them from duplicates, lookalikes, and unrelated entities.
  • Work with messy data, including names, aliases, domains, websites, firmographic attributes, multilingual records, and data hierarchies.
  • Define benchmark datasets, metrics, baselines, and error-analysis processes.
  • Design and execute experiments to validate hypotheses.
  • Compare LLM-assisted approaches against lower-cost alternatives.
  • Analyze model behavior, edge cases, and trade-offs.
  • Consider inference economics and scalability from the beginning.
  • Communicate experimental findings and recommendations to engineering and business stakeholders.
  • Independently establish experimental pipelines and research approaches.
  • Clearly document both successful and unsuccessful experiments.

What they require

  • You are an experienced Data Scientist with strong applied Machine Learning expertise and a track record of building and evaluating models using real-world, messy, large-scale data.
  • You are comfortable working with embeddings, semantic similarity, LLMs, NLP, classification, and both supervised and unsupervised learning.
  • You approach ambiguous problems through structured experimentation, clearly defined hypotheses, baselines, metrics, and error analysis.
  • You are highly autonomous, intellectually honest about experimental results, and able to clearly communicate technical recommendations and trade-offs to engineering and business stakeholders.
  • 5+ years of professional Data Science / Machine Learning experience.
  • Strong applied Machine Learning fundamentals.
  • Excellent Python and SQL skills.
  • Hands-on experience with embeddings and semantic similarity.
  • Practical experience applying LLMs to real-world problems.
  • Experience with supervised and unsupervised learning.
  • Strong experience with classification and NLP.
  • Working knowledge of neural networks and transformer architectures.
  • Hands-on experience with TensorFlow, PyTorch, PyCaret, or equivalent ML frameworks.
  • Experience retraining or maintaining classification models in production.
  • Strong experimental design and model evaluation skills.
  • Experience defining baselines, metrics, test sets, and error-analysis processes.
  • Ability to evaluate model quality and demonstrate measurable improvements.
  • Strong understanding of scalability and ML inference costs.
  • Strong English communication skills.
  • Strong analytical and experimental mindset.
  • Intellectual honesty and willingness to communicate negative results.
  • Strong autonomy and self-direction.
  • Excellent written and verbal communication.
  • Ability to defend technical recommendations with stakeholders.
  • Strong problem-solving skills.
  • Comfort working with ambiguity and large-scale datasets.
  • Ability to balance model quality, cost, and scalability.
  • Preferred: Entity resolution, record linkage, or deduplication experience.
  • Preferred: Ranking and similarity scoring.
  • Preferred: Retrieval, clustering, or candidate-generation techniques.
  • Preferred: LLM/embedding solutions designed for cost and scale constraints.
  • Preferred: Experience with company, domain, website, or firmographic data.
  • Preferred: Experience working with multilingual datasets.
