Web App Developer

Job Title Web App Developer Job Description Summary Our Enterprise Data team is building a Databricks-native data platform spanning master data management, AI-powered data quality and lineage, and a suite of internal tools used by data stewards, analytics engineers, and business stakeholders across multiple global regions. We are hiring a mid-level Web Application Developer to design, build, and operate the front-end and API layer of these tools — with Databricks Apps as the primary deployment target and Unity Catalog as the data authority. You will work closely with data engineers, platform architects, and business stakeholders to turn complex data workflows — stewardship queues, lineage dashboards, quality monitoring — into polished, production-grade web applications that feel enterprise-ready without sacrificing developer velocity.
