About the Role :
At Healthify, we're building technology that helps millions of people manage their health. Our engineering challenges span large-scale consumer applications, complex backend systems, and increasingly AI-powered products.
We're looking for a strong Full Stack Engineer who is equally comfortable building sophisticated frontend experiences and designing scalable backend systems.
What You'll Work On :
Frontend Engineering & Product Development :
- Build and maintain production web applications using React, TypeScript, and JavaScript.
- Work with modern React frameworks such as Next.js and React Router.
- Understand and apply Client-Side Rendering (CSR), Server-Side Rendering (SSR), and other rendering strategies.
- Independently translate Figma designs into responsive, polished, and intuitive product experiences.
- Optimize frontend performance, rendering, network requests, and user experience.
Backend Engineering & System Design :
- Design, build, and maintain backend services using Python, Django, or FastAPI.
- Develop APIs, background jobs, integrations, and services that support production applications.
- Work with relational and NoSQL databases, including schema design, indexing, and query optimization.
- Build systems with scalability, reliability, latency, and operational efficiency in mind.
Performance, Scalability & Engineering Fundamentals :
- Understand how applications behave end to end, from the browser and network layer to databases.
- Identify and solve performance bottlenecks involving network latency, database queries, and caching.
- Make informed technical decisions based on trade-offs involving performance, maintainability, and cost.
AI-Powered Engineering & Applications :
- Work on products that integrate LLMs, AI agents, and intelligent workflows.
- Understand the fundamentals of AI application architecture, including model APIs, tool calling, and context management.
- Use AI-assisted development tools effectively to accelerate implementation, testing, and debugging.
What We're Looking For :
- Strong, hands-on experience across both frontend and backend development.
- Frontend : Strong command of JavaScript, TypeScript, React, and modern frontend architecture.
- Product development : Ability to independently take Figma designs and build complete, production-ready user experiences.
- Backend : Hands-on experience building production services using Python with Django or FastAPI.
- Databases : Solid understanding of SQL and NoSQL databases.
- Core engineering fundamentals : Strong understanding of data structures, networking, HTTP, caching, and concurrency.
- Production experience : Experience building, deploying, maintaining, and scaling real applications.
- Independent ownership : Ability to understand requirements, make architectural decisions, and deliver features end to end.
- Engineering judgment : Ability to reason through unfamiliar problems and understand trade-offs.
