Senior Product Engineer

Senior Product Engineer

Location: New York City (Hybrid, 3 days in office per week)

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 product engineer to own the user-facing experience of our platform.

This role focuses on turning complex clinical workflows into interfaces that feel simple, reliable, and delightful. You’ll build multi-step forms, workflow-driven user interfaces, and product features that clinicians depend on every day.

You’ll also be building new product surfaces that do not exist yet. Today the system has a small set of core workflows, and over the next year that number will grow significantly. This role is about creating those new capabilities from scratch, not maintaining an existing UI.

You’ll work closely with the CTO to integrate those interfaces with backend systems and maintain clear API contracts. This role is frontend-heavy but requires comfort reasoning about backend behavior when debugging integration issues.

We use tools such as Claude Code, Git Hub Copilot, and Codex heavily throughout development. They are a normal part of how we move quickly on implementation, exploration, and iteration.

Engineers are responsible for what ships. We expect people to understand system behavior, review generated code carefully, debug failures, and maintain a high bar for reliability, security, and production quality.

We look for engineers who use AI for leverage while still owning their code end-to-end. We review meaningful changes together as a team so everyone maintains context on how the system works end-to-end.

• Own the user interface and experience across core clinical and operational workflows

• Build production features using Next.js, React, and Type Script

• Implement complex multi-step forms and workflow-driven interfaces

• Build AI-powered tools that help clinicians with documentation, clinical decision support, and voice-driven workflows

• Work with generated API clients and maintain frontend/backend contract alignment

• Translate real-world workflow requirements into usable software

• Build new product capabilities from scratch as the platform expands

• Collaborate closely with product, design, and clinical stakeholders

• Use AI development tools to accelerate implementation while maintaining code quality

• Participate in code reviews and technical planning

Next.js, Type Script, Tailwind, Turborepo, Python (Django, async-first), Postgre

SQL, workflow state machines, and clinical integrations using Medplum and FHIR.

Our services run on AWS and Kubernetes, and we rely on Terraform for IaC and Datadog for APM and infrastructure monitoring.

We maintain automated testing and deployment pipelines using Github Actions and integrate with AI providers including Google, Anthropic, and OpenAI.

• You independently scope and deliver production features

• You build new product surfaces that become core parts of the system

• Complex workflows feel simple to the people using them

• The product behaves predictably in real clinical settings

• You use AI tools effectively while maintaining ownership of system behavior

• Frontend code remains maintainable as the system grows

• You can debug a production issue that crosses the frontend/backend/infrastructure boundary without waiting for someone else

• 5+ years building production web applications

• Strong Type Script experience and proficiency with React and Next.js

• Experience building complex multi-step forms or workflow-driven interfaces

• Familiarity with API contracts and backend integrations

• Comfortable tracing application behavior across frontend and backend systems,…
