You Are:

We are seeking an AI/ML Engineer to build the intelligent systems that power identity resolution and data accessibility within our Customer Data Platform (CDP) - the authoritative source of truth for customer data across the entire US adult population.

The opportunity:

* Hybrid: In office/remote

* Develop and deploy entity resolution models to match and deduplicate customer records across multiple systems - directly impacting the accuracy of CDP as the source of truth

* Implement probabilistic matching techniques (e.g., Fellegi-Sunter) and ML models (gradient boosting, neural classifiers) for record linkage across the US adult population

* Build candidate blocking pipelines using phonetic algorithms (Soundex, Double Metaphone), token similarity, and LSH to handle billions of potential match pairs efficiently

* Apply fuzzy matching techniques (Levenshtein, Jaro-Winkler, Jaccard) for customer attributes such as name, address, phone, and identifiers

* Develop clustering algorithms (DBSCAN, hierarchical clustering) to create unified "golden customer profiles" that serve as the authoritative representation of each individual

* Build embedding-based similarity systems using Sentence-BERT or transformer-based models for semantic matching

This position description identifies the responsibilities and tasks typically associated with the performance of the position. Other relevant essential functions may be required.

What you need:

* Bachelor's or Master's degree in Computer Science, Data Science, or related field

* 3+ years of experience in ML/AI engineering

* At least 1 year of experience in entity resolution, record linkage, or deduplication - ideally at scale

* Technical Skills:

* Programming: Python (required)

* Libraries: scikit-learn, HuggingFace Transformers, RapidFuzz, jellyfish

* Experience with LLM APIs (OpenAI, Anthropic) and prompt pipelines

* Strong SQL skills and experience with Spark or Dask for distributed processing

* Familiarity with vector databases and embedding-based retrieval

* Experience with ML lifecycle tools (MLflow or similar)

* Understanding of data quality metrics and how identity resolution impacts downstream trust

* Knowledge, Skills, and Abilities

* Strong understanding of ML fundamentals and similarity matching techniques applied to customer identity

* Ability to work with large, messy, real-world datasets spanning hundreds of millions of records

* Understanding of precision/recall tradeoffs in identity resolution and their impact on data trust

* Good problem-solving and analytical skills

* Ability to collaborate with data engineering, platform, and business teams to deliver accurate customer profiles

* Licenses and Certifications
