Job Summary:
Mochi Health is an innovative company focused on transforming healthcare through technology. They are seeking a Senior Front-End Engineer to develop and optimize user interfaces that enhance patient and provider interactions, ensuring a seamless experience in their AI-driven healthcare marketplace.
Responsibilities:
• Build High-Density Healthcare Interfaces: You will build the complex tools our clinical team relies on to treat patients safely. You will architect dynamic, multi-step medical intake engines, high-density provider charting dashboards, and patient-facing applications that handle sensitive PHI with perfect state synchronization.
• Master Client-Side Architecture: Healthcare data is heavy and highly relational. You will design robust, scalable frontend architectures that manage complex state, handle asynchronous data fetching cleanly, and ensure interfaces feel instantaneous even when underlying APIs are slow.
• Collaborate Across the Client Ecosystem: While your primary domain is the web, Mochi also heavily leverages React Native and Expo for our mobile applications. You will work closely with mobile engineers to establish shared state patterns, reusable business logic, and a unified architectural standard across all client platforms.
• Champion the User Experience: You don't just implement specifications; you deeply care about how patients and providers experience Mochi. You sweat the details of the UI and possess the strong product sense required to make pragmatic, high-quality design decisions on the fly using our component systems that measurably improve patient outcomes.
• Own Frontend Reliability: You are responsible for what happens after the code ships. You will own the frontend deployment pipelines, establish strict performance budgets, and manage client-side observability and error tracking (e.g., Sentry, Datadog) to catch regressions before our patients do.
• Build Agentic Workflows: Mochi is an AI-first engineering org. You will not only utilize frontier agentic models to accelerate your own development, but you will also integrate AI capabilities directly into our product interfaces to automate clinical operations and scale our provider workflows.
Qualifications:
Required:
• 5-7+ years of frontend engineering experience.
• Experience building and operating production React applications that handle real complexity.
• Deep understanding of the React render cycle and complex data flows.
• Knowledge of server-side rendering, static generation, and client-side fetching.
• Ability to design robust, scalable frontend architectures.
• Strong eye for design and ability to unblock yourself visually.
• Experience with frontend deployment pipelines and client-side observability.
• Excellent communication skills and ability to thrive in cross-functional environments.
• Excitement to work in-person 5 days a week in the San Francisco office.
Preferred:
• Experience with TypeScript, Next.js, Tailwind CSS, and modern state management/data fetching tools (e.g., React Query, Zustand).
• Demonstrated track record of setting technical direction across teams if targeting Staff leveling.
• Experience using frontier agentic tools (e.g., Codex 5.3, Claude Opus 4.6) to build faster.
