Join Tech @ Ro to build the future of healthcare, from the ground up! At Ro, we believe that when people achieve their health goals, they can achieve their life goals. The highest-leverage way to move society forward is to give people their health, and the current healthcare system isn’t built to do that. It was built to bill, not to serve patients. We’re building a new system. One where the patient is in control. One designed from scratch for the digital age. At Ro, technology isn’t just a function… It's core to how we deliver care. We’ve built a vertically integrated healthcare platform that connects telehealth, diagnostics, pharmacy, and logistics into a seamless, end-to-end experience for millions of patients. …and we’re just getting started.  As part of Tech @ Ro, you’ll work on systems that operate at scale, with an opportunity to: Solve complex, high-concurrency problems across a full-stack platform Build and ship quickly with tight feedback loops and real-world impact Own systems end-to-end, from architecture to production performance Work alongside experienced operators, technical leaders, and clinicians Help define how modern healthcare should be delivered We’re a performance-driven team with a strong sense of ownership and urgency. We move fast, learn quickly, and hold a high bar for what we build, and do so with a big heart — because patients depend on it. If you’re motivated by impact, scale, and the chance to help lead the patient revolution, come build with us. The Role:   At Ro, our mission is to provide world-class healthcare by putting patients first - and that mission depends on reliable, secure, and scalable systems. As a Staff SRE on the infrastructure team, you’ll sit at the core of that effort: owning the reliability of our production systems, hardening infrastructure and building tools that empower our engineers to ship safely and confidently.   You will work across teams to drive uptime, performance and observability – partnering closely with product, platform and security engineers.    From designing resilient systems to shaping incident response practices, this is a role for engineers who thrive on impact and care deeply about operational excellence.
