Frontend Engineer

we make it easy for developers and AIs to build on health data. hundreds of wearables, sensors, labs, and health apps — connected, normalized, and made intelligent through a single platform. 1,000s of developers and AI labs build on Terra today. we process 15+ billion health data events per year. and we are just getting started.

the health OS

health data is fragmented. every device, every app, every 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.

Terra was founded in 2021 and operates from London, San Francisco, and South Korea.
we are funded by Y Combinator (W21), General Catalyst, Samsung NEXT, NEXT Ventures, and many of the world's finest investors.

we are a team of engineers, researchers, builders, and designers. we hire people who get things done, think from first principles, and learn ferociously. we default to yes. we ship fast. we hack. we build. we don't do bureaucracy.

At Terra, we aim to be the infrastructure for health data and products alike. To do this, we need world‑class engineers capable of making the most intuitive and pleasing UI for our customers and internal team. Branding is also a very important aspect here  will work directly with product engineers to build and evaluate UI/UX to ensure everyone stays on their happy path!

We currently use AWS and GCP along with NextJS (Typescript), HTML, CSS, Tailwind for frontend. We do not discriminate by language and if you have a preferred language within reason, we are happy to let you build with it!

We believe outstanding engineers don’t need extensive training from big‑tech companies but rather able to learn through passion, curiosity, and resourcefulness.
