About the Role

This is a high-impact individual contributor role at the core of our backend engineering team, building the services, APIs, and data systems that power Sidecar Health's platform. You'll own complex, performance-critical systems end-to-end — from design through deployment — and make the architectural decisions that keep us fast and reliable as we scale. If you treat every feature like your name is on it and want to build things that matter in healthcare, this is the role for you.
