Senior Backend Engineer, Workflow Systems
About The Position
Kinstead is building the AI-native operating system for independent healthcare, enabling nurse practitioners to launch and run their own clinics. We replace the fragmented, manual infrastructure behind healthcare with a single, intelligent system so clinicians can spend their time on care, not paperwork. This creates a new model of care, one where clinicians practice on their terms and patients get consistent, community-rooted care. We’re backed by Wisdom Ventures and founders and executives from Pomelo Care, Flatiron Health, Roivant, and PathAI on our mission to deliver better care. We’re hiring a senior backend engineer to build and own core backend systems and application logic. You’ll design and build the services that power reliable clinical and operational workflows, including APIs, background processing, and system behavior under real-world conditions. This role focuses on reliability, correctness, and predictable execution as the product grows. You do not need prior healthcare or FHIR experience. We care more about strong backend fundamentals, sound engineering judgment, and the ability to ramp quickly on a complex domain. You’ll work closely with the CTO on system design while maintaining ownership of implementation and operational correctness.
