TigerData (FKA Timescale) [ Global | 100% Remote | Multiple Roles: Eng, Product + more ] We began in 2017 as Timescale, focused on making PostgreSQL the best database for time-series data. As our customers evolved, so did we.

Today, more than 2,000 companies use our technology to power real-time analytics, agentic applications, and high-ingest operational systems.
