Recruitment Background<\/h2>\n
\n

VISASQ operates a knowledge platform dedicated to its mission: "We make insightful connections possible." Connecting businesses with precisely the right expertise across 190+ countries and a network of over 800,000 experts, our Global Expert Network Service (ENS) provides high-precision matching across region and language barriers for professional clients, including management consulting firms and financial institutions.<\/p>\n

In an era where generative AI has made publicly available web information easily accessible, the value of unstructured first-hand human experience and knowledge has grown exponentially. Currently, vast amounts of data continue to accumulate across multiple products and multi-cloud environments (Azure and GCP).<\/p>\n

However, the precision of AI agents relies fundamentally on the quality of the underlying data. Core elements\u2014such as company master identity resolution, employment history accuracy, and compliance verification reliability\u2014directly impact the quality of AI agent decision-making.<\/p>\n

While we are incrementally improving data quality within our current structures, we are looking toward building a unified master data platform that consolidates multiple data sources. We are seeking a Data Platform Engineer who can design the data platform architecture that fuels our AI products and lead complex, data-driven design decisions based on empirical evaluation.<\/p>\n<\/div>\n
