Help us deliver ergonomic product APIs that efficiently and maintainably handle large quantities of financial pricing data.

Apply Now About this role The Market Data team owns the fundamental pricing data that most people associate with financial markets - trades, quotes, and aggregates. Market Data engineers manage high-volume data from ingestion into our Data Platform to presentation through our many customer-facing APIs (REST + WebSockets). They also work on minimizing latency in our streaming data pipeline. All engineers work directly with our Product and Support managers to consistently deliver an industry-leading customer experience. The Market Data Team closely collaborates with our Account Services, Infrastructure Platform, and Data Platform engineering teams.

Because we are a lean engineering org (<30 people), there are many opportunities to wear multiple hats, lead technology changes, and dive deep into many technologies. The core technologies in the Market Data team include but are not limited to Go, Kubernetes, Docker, GitHub Actions, RESTful APIs, gRPC/Protobuf, WebSockets, Kafka, Redis, SQL, and (a little) Rust.
