Job Summary:
Mochi Health is an innovative company focused on transforming healthcare through technology. They are seeking a Senior Fullstack Engineer to build complex tools for clinical teams, connect backend systems to user-friendly interfaces, and enhance patient experiences through high-quality software solutions.
Responsibilities:
โข 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 apps that handle sensitive PHI with perfect state synchronization.
โข Bridge Clinical & Client: Connect our complex backend medication ordering and fulfillment pipelines to intuitive, highly responsive frontend interfaces. You will translate dense healthcare requirements into seamless digital experiences.
โข 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 that measurably improve patient outcomes.
โข Own the Full Lifecycle: True full-stack means owning the delivery. You will design the database schema, write the API, build the React interface, deploy the service, and own both backend reliability and client-side error tracking in production.
โข 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 to automate clinical operations and scale our provider workflows.
โข Raise the Engineering Bar: Own key architectural decisions across the stack, systematically upgrade legacy code, and elevate the engineers around you through rigorous code review, testing practices, and technical standards.
Qualifications:
Required:
โข 5-7+ years of full-stack engineering experience.
โข Experience building and operating production systems that handle real complexity.
โข Mastery of client-side state and performance management.
โข Understanding of server-side rendering vs. client-side fetching, caching strategies.
โข Experience with data modeling, schema design, and API boundaries.
โข Comfortable with (or eager to master) Kubernetes, Terraform, AWS, and CI/CD.
โข Experience deploying code and owning system reliability.
โข Familiarity with frontier agentic tools (e.g., Codex 5.3, Claude Opus 4.6).
โข Excellent communication skills and ability to thrive in cross-functional environments.
โข Excitement to work in-person 5 days a week in the San Francisco office.
โข Demonstrated track record of setting technical direction across teams (if targeting Staff leveling).
