About the Company
Terra is the health operating system. 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. Thousands 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.
About the Role
Terra is the unified API for health and fitness data. We connect developers and AI labs to 500+ wearable, sensor, and biomarker sources through a single normalized schema. Over 15 billion health data events flow through our infrastructure every year. The companies building the world's best health products run on Terra.
We are hiring a Senior Customer Engineer—someone who can operate at the intersection of deep technical ability and customer‑facing ownership. This is not a support role with scripts and macros. This is an engineering role where the customer is the context. You will be the most technical person our customers ever talk to, and the most customer‑aware person on our engineering team.
You will own the full integration lifecycle: from first API call to production‑grade data pipeline. You'll debug webhook delivery, troubleshoot OAuth flows across dozens of wearable providers, write reference implementations, and ship tooling that makes every developer on Terra's platform more successful. When something is broken at 2 am and a customer's health app is down, you're the person who fixes it and then writes the runbook so it never happens again.
What You Will Do
- Lead technical onboarding for customers integrating with the Terra API—from initial sandbox setup through production go‑live. You are accountable for time‑to‑first‑data. Architect integration patterns tailored to each customer's stack: REST polling vs. webhook‑driven pipelines, batch historical backfills vs. real‑time streaming, mobile SDK vs. server‑side.
- Build and deliver reference implementations in Python, Node.js, and other languages that demonstrate best practices for consuming normalized health data (activity, sleep, heart rate, workouts, biomarkers). Work directly with customer engineering teams to review their integration code, flag anti‑patterns, and accelerate production readiness.
- Debug and resolve complex technical issues: troubleshoot data pipeline issues across Terra's infrastructure—webhook delivery failures, data gaps from upstream providers (Garmin, Fitbit, Oura, Apple Health, etc.), OAuth token expiry, and normalization edge cases. Investigate issues that span multiple systems—from our API gateway and webhook retry logic to the customer's receiving endpoint. Reproduce customer‑reported bugs, isolate root causes, and either fix them yourself or deliver precise, actionable bug reports to internal engineering with reproduction steps, logs, and proposed fixes.
- Own incident communication for customer‑impacting issues: clear, honest, and technical. No hiding behind 'we're looking into it.'
- Build internal tooling and automation: identify patterns in customer issues and build tooling to eliminate them. If five customers hit the same webhook misconfiguration, build a validator. If a data gap keeps recurring from a specific provider, build monitoring. Contribute to Terra's developer documentation, API reference, integration guides, and troubleshooting runbooks.
- Develop internal dashboards and diagnostic tools to accelerate issue resolution—query health, webhook delivery status, data freshness, provider connectivity. Automate repetitive operational tasks: data backfills, provider re‑authentication.
