Full Stack Engineer

## About the company myStoria is AI-powered, patient-side infrastructure that turns the patient into a contributing node in the healthcare system. We make being a patient dramatically easier — organizing your health, carrying your records, and helping you show up to care prepared. And we're building the layer that makes the patient a true source of truth across a fragmented system. We're a small, fast-moving team that ships constantly. ## About the role We are looking for a product-minded engineer who is strongest on frontend/mobile, but comfortable working across the stack when needed. You'll own core user-facing flows in our new mobile-first experience and help us bake AI into the product in practical ways, not just as a buzzword. You should be excited about: - Shipping quickly to real users - Using AI tools (ChatGPT, Copilot, Cursor, etc.) to move faster - Working directly with the founder, engineering, product, and clinical team - Turning messy real-world health journeys into clean, usable interfaces This is a hands-on role with high ownership, not a management position. ## What You Will Do - Build and ship mobile-first features - Implement core flows in our app (onboarding, messaging, timelines, data views, etc.). - Work mostly on frontend/mobile, while being comfortable jumping into backend where needed. - Integrate AI into real product surfaces - Work with product, engineering, and clinical teams to turn LLM capabilities into features (e.g., contextual chat, summarization, routing, smart prompts). - Prototype quickly with AI tooling and iterate based on user feedback. - Own features end-to-end - Take a problem from rough requirements to technical design, implementation, rollout, and monitoring. - Make pragmatic decisions around tradeoffs, tech debt, and speed vs. polish. - Collaborate tightly with the rest of the engineering team - Pair with other engineers on architecture, code reviews, and shared components. - Work directly with the founder and Head of Product to shape scope, UX, and roadmap. - Give and receive direct feedback; push back when something doesn't make sense. - Build for security and reliability from day one - Handle sensitive health data with care and good judgment. - Contribute to patterns that keep our stack secure and maintainable as we scale. ## Our current stack You don't need all of these on day one, but you should be comfortable picking up similar technologies quickly. - Frontend/mobile: React / React Native, Next.js - Backend: Node.js / TypeScript, APIs (REST/GraphQL), serverless / BaaS (e.g., Convex, Firebase, or similar) - Data & infra: Postgres or similar, GCP/AWS, auth, basic observability - AI: LLM APIs (e.g., OpenAI, Anthropic, Gemini), prompt design, retrieval patterns ## You might be a fit if you: - Have 4+ years of experience building production web or mobile products. - Are strongest in frontend/mobile (React / React Native or similar) but have enough backend experience to build and debug APIs, data models, and integrations. - Have shipped real features that users touch every day, not just internal tools or prototypes. - Use AI tools as leverage: - You already use ChatGPT / Copilot / Cursor or similar to speed up your work. - You're comfortable reading and critiquing AI-generated code instead of blindly trusting it. - You care about UX, edge cases, and whether something actually solves the user's problem. - Are comfortable with ambiguity and constraint - You can work with incomplete specs and help define what "v1" should be. - You're okay with switching contexts when priorities change. - Care about privacy and ethics in health and AI. ## Nice to have - Experience with: - Mobile apps in production (App Store / Play Store). - Healthtech, PHI, or regulated environments. - Chat-based interfaces or LLM-powered products. - Analytics and experimentation (feature flags, A/B tests, product metrics). - Previously worked in a 0 → 1 or seed/Series A environment. ## What we offer - Competitive salary for seed stage + meaningful equity in the form of stock options. - Direct impact: your work will be in the hands of patients quickly - Tight feedback loop with real users and clinicians - A small, senior team that cares more about outcomes than ceremonies - Flexibility in where and how you work, as long as you deliver
