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, Roo Capital, and leaders from PathAI, Pomelo Care, and Flatiron Health on our mission to deliver better care. About The Role We're hiring a founding product engineer to own the user-facing experience of our platform. You'll work closely with the CTO, founders, designers, and clinical stakeholders to turn complex clinical and operational workflows into software that feels simple, reliable, and intuitive. This isn't a role where product requirements are handed to you in finished form. You'll help discover the right solution alongside clinicians and designers, make thoughtful product and technical tradeoffs, and build features from idea to production. You'll own the frontend, but not in isolation. You'll influence API design, data models, and overall architecture to make the entire product feel cohesive. We expect engineers to think beyond components and pages, thinking about how the entire product should behave. This role is a great fit if you enjoy turning messy real-world workflows into polished software, making product decisions, and building alongside customers. It is probably not the right role if you prefer narrowly scoped implementation work or highly specified roadmaps. How We Work We use AI coding tools such as Claude Code and Codex every day. We expect every engineer to be comfortable incorporating AI into their development workflow. AI accelerates implementation, but engineers remain responsible for system design, debugging, code review, and everything that reaches production. We care far more about engineering judgment than lines of code. Great engineers know when to trust AI, when to question it, and ultimately take responsibility for what ships.
