Founding Product Engineer

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.

Responsibilities

• Become the person the team relies on for the frontend and overall product experience.
• Ship clinician-facing workflows that providers use every day and continually improve them based on real customer feedback.
• Build frontend foundations that make the rest of the engineering team faster, more consistent, and more confident shipping product.
• Work comfortably across design, frontend, backend, and infrastructure to solve customer problems end to end.
• Be someone the team trusts with ambiguous, high-impact projects where there isn't an obvious right answer.

Requirements

• Demonstrated experience leading significant technical initiatives or owning major product areas.
• Strong experience with React and Next.js.
• Experience owning user-facing features from concept through production.
• Comfortable collaborating across the frontend/backend boundary, including working with APIs and debugging backend behavior when needed.
• Experience collaborating directly with designers, customers, or domain experts to shape product direction.
• Strong product intuition, engineering judgment, and debugging skills.
• Comfortable working in a fast-moving startup environment.
• Comfortable using AI development tools while maintaining ownership of the systems you build.
• Able to commute to Kinstead's Columbus Circle office 3x per week.

Nice to Have

• Experience with healthcare, FHIR, or other regulated software.
• Experience as an early or founding engineer at a startup.
• Experience building products used throughout the workday where usability and workflow matter as much as correctness.
• Experience working closely with designers to evolve a design system over time.

What You’ll Own

• Own major clinician-facing workflows from whiteboard to production, including implementation, testing, rollout, and iteration.
• Help define product behavior alongside designers, founders, and clinicians rather than waiting for finished specifications.
• Drive frontend architecture and technical direction across the provider and patient applications.
• Work side-by-side with our product designer to iterate quickly from rough concepts to polished production experiences.
• Work comfortably across the frontend/backend boundary, influencing APIs, data models, and overall architecture to make the entire product feel cohesive.
• Debug complex production issues that span browsers, APIs, third-party integrations, and infrastructure.
• Help shape our engineering culture through thoughtful code reviews, technical discussions, and pragmatic decision making.
