Join Outlive Help Build the Operating System for Better Long-Term Health Outlive is translating the principles of Medicine 3.0 into a practical, evidence-based product that helps people change the trajectory of their health. We focus on what matters most. Setting meaningful long-term goals, understanding the risks that can get in the way, and selecting the tactics that move the needle. Our approach is grounded in the ideas Peter Attia has spent his career developing. A deliberate practice with clear metrics and truly personalized plans that extend healthspan, not just lifespan. We're building a system that takes the essential pillars of long-term health and makes them actionable. Our goal is simple. Give people a structured way to understand where they are today, what levers truly matter, and how to make durable progress over time. Why Outlive You will shape the foundation, not optimize at the margins We're in the earliest stages of building something that doesn't exist anywhere else. There are no templates. No inherited systems. The work requires people who want to solve first-principles problems and create frameworks built to last. Science and design sit at the center of everything We aim to convey complex ideas with clarity and precision. That means pairing rigorous scientific thinking with thoughtful, intuitive design; so users can understand why something matters and how to act on it. AI is part of how we work The product itself is grounded in science and behavior change. But as a team, we use AI to think, test, draft, explore, and accelerate our work. It's a tool that enhances judgment and craftsmanship, not a replacement for either. We care about rigor, honesty, and high standards The team is small, driven, and aligned around a shared goal: build something that meaningfully improves long-term health. We challenge ideas respectfully, expect clear reasoning, and operate with a bias toward action. Precision matters. So does integrity. Role Overview As a Backend Engineer , you'll be responsible for designing and evolving the core services that power Outlive's health intelligence platform. This includes user identity, data ingestion, scoring systems, background processing, and secure integrations with external services. You'll work primarily in TypeScript with NestJS , deploying to Cloud Run and Cloud Functions on GCP.
