You have 5-7+ years of frontend engineering experience. You've built and operated production React applications that handle real complexity, crossing the boundary between dense data visualization and polished, accessible user experiences. * You master React and state architecture fundamentals. You understand the React render cycle deeply, moving beyond surface-level hooks to truly orchestrate complex data flows. You know the tradeoffs between server-side rendering, static generation, and client-side fetching, and you leverage tools like Next.js pragmatically without over-complicating the architecture. * You are an independent product builder. You don't need a pixel-perfect Figma file to ship great software. You have a strong eye for design and can unblock yourself visually while maintaining strict adherence to our design system and brand language. * Your workflows are altered by AI. You are already using frontier agentic tools (e.g., Codex 5.3, Claude Opus 4.6) to build faster. You can describe specific ways these models have structurally changed how you code, while retaining the deep technical skepticism required to audit, verify, and own its output. * You are a collaborative builder. You have low ego, high standards, and excellent communication skills. You thrive in cross-functional environments where engineering requirements are heavily shaped by healthcare regulations, compliance, and patient safety. * You are excited to work in-person. You want to build alongside the team 5 days a week in our San Francisco office. * If you are targeting Staff leveling: We expect a demonstrated track record of setting technical direction across teams, navigating deep ambiguity, and measurably leveling up the engineers around you. * Our frontend stack is TypeScript, React, Next.js, Tailwind CSS, and modern state management/data fetching tools (e.g., React Query, Zustand). Experience with these is a strong plus, but we index on engineering fundamentals, web performance, and product sense over framework dogmatism., 2. Technical round (2 hrs, remote) - Practical coding in react + application design conversation. Real problems, not LeetCode. 3. Behavioral interview (45 min, remote) - Technical background, motivation, and what you're looking for. 4. Team meet (2 hrs on-site) - Come to our SF office to meet your future manager, engineering peers, and product partners for 30-minute 1:1s, concluding with a quick recruiter wrap-up. We are ready to move as fast as you are. We can go from the first intro to offer in two weeks, or pace the rounds to comfortably fit your current work schedule. Our Core Technologies Include: Typescript, Javascript, Node.js, Next.js, React, React Native, SQL, Redis, Redux, New Relic, Kubernetes, CSS, AWS, Cypress, Docker, Express ## Description * 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. ## Related Videos - [But, you're not Facebook](https://www.wearedevelopers.com/videos/378-but-you-re-not-facebook) - [From Doubt to Confidence: How Sentry Uses Verdaccio to Bulletproof SDK Releases](https://www.wearedevelopers.com/videos/739-from-doubt-to-confidence-how-sentry-uses-verdaccio-to-bulletproof-sdk-releases) - [Reducing LLM Calls with Vector Search Patterns - Raphael De Lio (Redis)](https://www.wearedevelopers.com/videos/1714-reducing-llm-calls-with-vector-search-patterns-raphael-de-lio-redis) - [Boost Productivity with AI: Figma & Playwright MCP Workflows - Aris Markogiannakis](https://www.wearedevelopers.com/videos/1768-boost-productivity-with-ai-figma-playwright-mcp-workflows-aris-markogiannakis) - [Microfrontends at Scale](https://www.wearedevelopers.com/videos/236-microfrontends-at-scale) - [Debugging in the Dark](https://www.wearedevelopers.com/videos/1658-debugging-in-the-dark) ## Related Articles - [16 Best Free React UI Libraries in 2025](https://www.wearedevelopers.com/magazine/148-16-best-free-react-ui-libraries-in-2025) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [The Best 7 Frontend Frameworks for Developers in 2025](https://www.wearedevelopers.com/magazine/400-the-best-7-frontend-frameworks-for-developers-in-2025) - [React Developer Salary [2023]](https://www.wearedevelopers.com/magazine/198-react-developer-salary-2023) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 133 - Back to Front](https://www.wearedevelopers.com/magazine/474-dev-digest-133-back-to-front)
