Senior Frontend Engineer - Remote Europe

This role is suitable for a Senior Frontend Engineer with professional Vue.js experience and strong JavaScript, Sass/CSS, component-based UI, MVC, Git, and agile development skills.

The candidate should be familiar with building maintainable, scalable, responsive, and mobile-friendly applications, creating polished interactions and visualizations, integrating RESTful APIs, and collaborating with backend engineers and UI designers.

They should also have experience writing unit and functional tests, optimizing frontend applications, applying UX and pixel-perfect design principles, and communicating effectively in a remote team; knowledge of TypeScript, Node.js, Ruby on Rails, Electron, or iOS is advantageous.

How would you structure a scalable Vue.js application with reusable components?

I would organize the application by feature or domain, separating reusable UI components, page-level components, state management, services, and API clients. Components should have clear responsibilities, well-defined props and events, and minimal coupling to business logic.

How do you manage state and data flow in a Vue.js application?

I prefer local component state for isolated concerns and a centralized store for shared or cross-page state. Data should flow predictably through props and events, while asynchronous API interactions should be encapsulated in services or dedicated store actions.

How would you consume and handle errors from RESTful APIs in a frontend application?

I would create a consistent API client layer that handles authentication, serialization, loading states, and common errors. Components should present useful feedback to users while logging or reporting unexpected failures for debugging and monitoring.

What techniques do you use to write maintainable and scalable Sass?

I use a modular architecture with variables, mixins, utilities, and component-level styles, while avoiding deeply nested selectors and excessive specificity. Naming conventions such as BEM and design tokens help keep styles predictable and reusable.

How do you ensure that a Vue.js application is responsive and mobile-friendly?

I use a mobile-first CSS approach with flexible layouts, responsive breakpoints, accessible controls, and touch-friendly interaction sizes. I also test across different viewport sizes and real devices to identify layout, performance, and usability issues.

What is your approach to unit and functional testing for frontend applications?

Unit tests should cover component behavior, utility functions, computed properties, and edge cases, while functional tests validate complete user workflows. I focus testing on observable behavior rather than implementation details and include API mocking for reliable isolation.

How would you optimize the performance of a JavaScript-heavy application?

I would measure performance first using browser profiling and real-user metrics, then address issues such as unnecessary re-renders, large bundles, expensive computations, and excessive network requests. Code splitting, lazy loading, memoization, virtualized lists, and optimized assets can significantly improve performance.

How do MVC and object-oriented concepts apply to frontend development?

MVC encourages separating presentation, application logic, and data responsibilities, which improves maintainability and testability. Object-oriented principles such as encapsulation, abstraction, and composition can be applied to services, models, and reusable application behavior without over-engineering the UI.

How do you collaborate with backend engineers and designers on a frontend feature?

I clarify requirements early, agree on API contracts and error formats with backend engineers, and confirm interaction details and responsive states with designers. I also communicate trade-offs, document decisions, and use incremental reviews to reduce integration problems.

What Git workflow do you use when working in an agile, distributed team?

I use focused branches and small, descriptive commits, then open pull requests for review with relevant tests and context. I keep branches synchronized, resolve conflicts carefully, and use continuous integration to validate quality before merging.
