We make it easy for developers and AIs to build on health data. Hundreds of wearables, sensors, labs, and health apps are connected, normalized, and made intelligent through a single platform. Thousands of developers and AI labs build on Terra today, processing over 15 billion health data events per year.
The health OS addresses the fragmentation of health data, where every device, app, and sensor speaks a different language. We built the health OS to solve that — a full-stack platform that turns raw, messy, siloed health data into something developers and AIs can reason over, build on, and ship with.
Founded in 2021, Terra operates from London, San Francisco, and South Korea, and is funded by Y Combinator (W21), General Catalyst, Samsung NEXT, NEXT Ventures, and many of the world's finest investors. Our team consists of engineers, researchers, builders, and designers who get things done, think from first principles, and learn ferociously. We default to yes, ship fast, hack, build, and avoid bureaucracy.
You will own and ship core platform systems that power how health data flows through Terra — from upstream data suppliers (wearables, health apps, sensors) into our unified schema, and out to downstream developers and AI consumers via our REST API, Streaming API, and webhooks. This is not a maintenance role. You will build new data connectors, scale real-time streaming pipelines, harden our authentication layer, and design the systems that handle millions of API calls per day.
You will work across the entire stack — from low-level data ingestion to developer-facing API surfaces. You will ship fast, iterate through feedback loops, and think in first principles. We don't have layers of process; we have ownership and velocity.
What You Will Build: Unified API
