About The Position

Kinstead is hiring a Senior Software Engineer to build and own core product functionality across the stack. You’ll design and implement the systems that power reliable clinical and operational workflows, from backend services and APIs to the frontend experiences that clinicians use every day. You’ll work on everything from application logic and asynchronous processing to user-facing features, collaborating closely with the rest of the engineering team to ship complete product capabilities. We care deeply about reliability, correctness, and building software that behaves predictably under real-world conditions. Many of their most interesting engineering problems involve workflow design, state management, integrations, and ensuring complex systems remain understandable as they grow. You do not need prior healthcare or FHIR experience. We care more about strong engineering fundamentals, sound technical 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, production quality, and the long-term health of the systems you build.

• 5+ years building production web applications
• Strong backend engineering experience with a modern server-side language or framework (Python, Go, Kotlin, TypeScript, Java, C#, or similar)
• Comfortable building product features across the stack, including React/Next.js
• Strong engineering judgment and debugging skills
• Comfortable owning features from design through production
• Comfortable using AI development tools while maintaining ownership of the systems you build
• Ability to commute to Kinstead’s Columbus Circle office 3x week

Responsibilities
