Position description

Position at LinkedIn

LinkedIn Data Standardization is a global organization operating in multiple locations including Sunnyvale, CA, USA (HQ); San Francisco, CA, USA; New York City, NY, USA; Dublin, Ireland. Through AI and human working together in harmony, Standardization takes LinkedIn’s raw, unstructured economic graph data and produces standardized data that has more human interpretable, less ambiguous and proper semantic structure. Everyday, we standardize PetaBytes of data in a nearly real-time platform, organize them in a Knowledge Graph, and serve them to LinkedIn Recommendation and Search, Ads Targeting, Question & Answering and Data Insights with A/B test control, online/offline data consistency and low serving latency. 

The engineering organization consists of 100+ ML/NLP scientists/engineers, infrastructure and system engineers, linguistic specialists. It is composed of five engineering teams, each with its own area of responsibility, that work synergistically to further our mission. These teams are Taxonomy, Member Data, Job Data, Company Data, and Internationalization. The Taxonomy team is responsible for creating the best professional ontologies for LinkedIn economic entities (titles, skills, companies, products, industries, education, geo locations, certificates etc.) in the world. The other data teams are building the life cycle of data, including ingesting data from Web, developing AI models and data infrastructure to extract/infer economic entities from raw member/job/company data, and proactively interacting with LinkedIn consumers/customers to smartly solicit their data (e.g., evaluating the expertise of LinkedIn members, assessing the qualification of job applicants, verifying the correctness of inferred/ingested data). The Internationalization team is dedicated to developing language-independent models and expanding non-English taxonomies. Our new Dublin team will create accurate and comprehensive company data across the globe for LinkedIn Sales, Marketing and Talent audiences, and build the end-to-end scalable LinkedIn data ingestion platform.

We all collaborate and function as one to create the best and the largest professional Knowledge Graph centered at people in the world with 1B+ nodes and 50B+ edges. Our work directly creates hundreds of millions of annualized revenue in data products like ads targeting, data insights, facet search, profile creation. Our work also provides rich features for Recommendation and Search AI models.
