The Reference Data team owns ingesting and serving metadata about each financial market Polygon.io supports as a product. Think about answering the questions: “What are the tickers on the New York Stock Exchange?” or “I wonder if Options markets have a holiday tomorrow?”. The Reference Data team also owns synthesizing sentiment analysis and related companies from our third-party data vendors. All engineers work directly with our Product and Support managers to consistently deliver an industry-leading customer experience. The Reference Data team collaborates closely with our Account Services, Infrastructure Platform, and Data Platform engineering teams.

Because we are a lean engineering org there are many opportunities to wear multiple hats, lead technology changes, and dive deep into many technologies. The core technologies in the Reference Data team include, but are not limited to, Go, Kubernetes, Docker, GitHub Actions, RESTful APIs, gRPC/Protobuf, Redis, PostgreSQL, SQL, Parquet, and (a little) Python.
