Senior Product Engineer

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

About The Role

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.

How We Work

We use tools such as Claude Code, GitHub 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.

What You'll Do

• Own the user interface and experience across core clinical and operational workflows
• Build production features using Next.js, React, and TypeScript
• 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

Our Stack

Next.js, TypeScript, Tailwind, Turborepo, Python (Django, async-first), PostgreSQL, 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.

What Success Looks Like

• 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

Requirements

• 5+ years building production web applications
• Strong TypeScript 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, including reading and debugging Python/Django code when needed
• Comfort working in a fast-moving startup environment
• Experience working in an AI-assisted development workflow

Nice to Have

• Experience with healthcare or regulated software
• Familiarity with FHIR or clinical data systems (helpful but not required)
• Strong product intuition and pragmatic engineering judgment

What It's Like to Work with Us

We're building something ambitious, and we care deeply about how we show up while we do it.

We stay close to clinicians

We spend time with the people we serve, in their practices and in their communities. The best ideas come from understanding their reality and building alongside them.

We take responsibility and move things forward

If something matters, we don't wait for perfect clarity. We step in, make progress, and figure it out together.

We turn what works into something that lasts

We solve problems in real time, then step back and build the systems that make it easier for the next clinician.

We use AI thoughtfully

We look for ways to reduce manual work so clinicians can focus on care. If something feels repetitive, we treat it as an opportunity to improve how we operate.

We care about building something meaningful

We're here to help clinicians create independent, community-rooted practices. That responsibility shapes how we make decisions and how we grow.

We are kind, direct, and low ego

We support each other, give honest feedback, and focus on getting to the right answer. We take the work seriously, but not ourselves.

Benefits

• Competitive salary and generous, early-stage equity (4-year grant)
• Health, vision, and dental benefits
• 401(k)
• Unlimited PTO
• Prime office in Columbus Circle with weekly team lunches
• Fun team events and offsites

We aim to pay competitively for our stage and the importance of the work. Compensation includes base salary, meaningful equity, and benefits, and is designed to align long-term incentives with the impact you'll have at Kinstead. In accordance with applicable laws, we provide a reasonable estimate of the salary range for this role. Final compensation will depend on a number of factors, including experience, skillset, and leveling, as well as internal equity considerations. For this role, the estimated base salary range is $160,000 - $205,000, with most candidates falling somewhere in the middle.
