OneMarketData Tech Stack

Enterprise tick data platform for quantitative finance and market surveillance

IT Services and IT Consulting Hoboken, NJ 201–500 employees Founded 2005 Privately Held

OneMarketData operates OneTick, a specialized data platform for financial institutions handling high-volume tick data, backtesting, and market surveillance. The stack is heavily AWS and Kubernetes—with active migration from EC2 to EKS, supported by Python, pandas, and ML libraries (scikit-learn, LightGBM)—reflecting both cloud modernization and the computational intensity of time-series analytics at scale. Current projects span ETL optimization (Airflow migration), observability (Prometheus, Grafana, Loki), and multi-account AWS infrastructure, while pain points cluster around distributed system complexity, data delivery SLAs, and cost optimization under high throughput.
