Frontend Engineer

This role is best suited for a Senior Frontend Engineer with 4+ years of experience building modern web applications and strong expertise in TypeScript and Svelte/SvelteKit. The candidate should be comfortable developing PWAs, creating performant and accessible interfaces with Tailwind, integrating APIs and health data systems, and ideally have exposure to Capacitor, Kotlin, Swift, healthcare standards (FHIR, HIPAA), or mobile ecosystems. They should enjoy working in a fast-moving startup environment, collaborate closely with designers and clinical teams, and care about reliability, UX, and building impactful healthcare products.

1. How would you structure a scalable SvelteKit application for a healthcare platform?
   I would organize the application by feature/domain, separate UI from business logic, and create reusable components and services. Strong typing and clear boundaries help maintain reliability as the application grows.

2. What advantages does Svelte offer compared to React or other frontend frameworks?
   Svelte shifts much of its work to compile time, reducing runtime overhead and bundle size. It often results in simpler code and improved performance for interactive applications.

3. How would you build a Progressive Web App that works reliably across Android and iOS?
   I would focus on responsive design, offline capabilities through service workers, proper caching strategies, and testing platform-specific behavior across devices.

4. How would you integrate device-native functionality into a web application using Capacitor?
   Capacitor allows PWAs to access native APIs through plugins. Custom plugins can be written in Kotlin and Swift when device features are not available through existing packages.

5. What security and privacy considerations are important when handling healthcare data?
   Healthcare applications require strict access control, encryption in transit and at rest, secure authentication, audit logging, and compliance with standards like HIPAA and SOC 2.

6. What is FHIR and why is it important in healthcare applications?
   FHIR is a healthcare data standard designed for exchanging clinical information between systems. It improves interoperability between providers, applications, and electronic health record systems.

7. How would you ensure accessibility in patient-facing applications?
   I would use semantic HTML, keyboard navigation support, screen reader compatibility, proper contrast ratios, and accessibility testing tools to ensure usability for all users.

8. How would you approach integrating health data sources like Apple HealthKit or CGMs?
   I would implement secure API communication, handle permissions carefully, validate incoming data, and design systems that remain reliable when data is delayed or unavailable.

9. How do you collaborate with designers and domain experts in healthcare projects?
   I work closely with designers to align implementation with UX goals and with clinical experts to validate workflows, ensuring that functionality is both usable and medically appropriate.

10. How would you ensure reliability and quality in a frontend healthcare application?
    I would use automated testing, strong TypeScript typing, code reviews, monitoring, and extensive validation of critical workflows since errors can directly affect patient experiences and safety.
