Senior Fullstack Engineer

Responsibilities

• 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.
• 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.
• 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.
• 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.

Requirements

• You have operated high-stakes systems. You have 5-7+ years of full-stack engineering experience. You've built and operated production systems that handle real complexity, crossing the boundary between complex backend domain logic and polished frontend user experiences.
• You get data modeling right. You think carefully about schema design and API boundaries, because you've seen what happens to the frontend when the foundational backend model is wrong.
• You

Additional Information

Healthcare is broken at the first step: patients can't find the right care, understand what it costs, or access the medications they need. Mochi Health is fixing this. We're building an AI-driven marketplace that makes healthcare discoverable-connecting patients to the right providers, transparent pharmacy pricing, and affordable medications. Over the past few years, we've grown rapidly by combining clinical expertise with technology that actually works for real people, not just hospital systems. Our platform does what legacy healthcare can't: it gives patients transparent pricing before they pay, personalized medication management that follows them across providers, and long-term access to their own medical records. We're proving that healthcare can be more affordable, more human, and far more intuitive than what exists today. Join a team that's rebuilding healthcare from the patient up. At Mochi Health, you'll work alongside people who value bold thinking, inclusive collaboration, and getting meaningful work into the world. If you want to do the most impactful work of your career, this is where to do it.
