Job Description

Here at Mindera Morocco, we are continuously developing a fantastic team, and would love it for you to join us.

We are looking for a Senior Frontend Software Engineer who not only brings strong technical skills but also excels in team fit, communication, and collaboration.

You will be responsible for designing and building high-performance, secure, and scalable front-end solutions — with a strong focus on React and Next.js, along with server-side rendering concepts (e.g., Node.js) to create seamless, isomorphic applications.

If you are approachable, communicate clearly, and enjoy working in a collaborative and positive team environment, we’d love to hear from you.

National and international expected traveling time varies according to project/client and organisational needs: 0%-15% estimated.

Technical Skills

Strong experience in React.js and Next.js.
Experience working with Redux or similar state management tools.
Familiarity with GraphQL and REST APIs.
Solid skills in HTML5, CSS3, and CSS pre/post-processors (SASS, LESS, PostCSS).
Experience with testing frameworks such as Jest, React Testing Library, and Enzyme.
Knowledge of performance optimization, observability tools (e.g., Grafana, Core Web Vitals), SEO, and accessibility best practices.
Varied tech experience is highly valued — exposure to different stacks and environments.

Ways of working

Agile methodologies such as Scrum and Kanban.
Passionate, self-driven, and comfortable working with little supervision.

🎯 Who is this job for?

This role suits a Senior-level Frontend Engineer with strong expertise in React.js and Next.js, including experience building SSR/isomorphic applications with Node.js. The candidate should have solid skills in state management (Redux), APIs (GraphQL/REST), testing (Jest, React Testing Library), and frontend fundamentals (HTML, CSS, performance, SEO, accessibility). They should be comfortable working in Agile environments, collaborating closely with teams, and taking ownership of scalable, high-performance frontend solutions with minimal supervision.

💬 Potential Interview Questions

How does Next.js handle server-side rendering (SSR), and when would you use it?
Next.js pre-renders pages on the server at request time, improving SEO and initial load performance. Use SSR for dynamic data that must be up-to-date on each request.
What are the key differences between CSR, SSR, and SSG in React/Next.js?
CSR renders content in the browser, SSR renders on each request, and SSG generates static pages at build time. Choice depends on data freshness, performance, and SEO needs.
How do you optimize performance in a React application?
Use techniques like memoization (React.memo, useMemo), code-splitting, lazy loading, and minimizing re-renders. Also optimize assets and monitor Core Web Vitals.
Explain how Redux works and when you would use it.
Redux is a centralized state management library using a single store and pure reducers. It’s useful for managing complex global state across large applications.
How do you handle data fetching in Next.js applications?
Use getServerSideProps, getStaticProps, or getInitialProps depending on the rendering strategy. For client-side fetching, use hooks like useEffect or libraries like SWR/React Query.
What are the benefits of using GraphQL over REST?
GraphQL allows clients to request only the data they need, reducing over-fetching and under-fetching. It also provides a strongly typed schema and better flexibility for frontend development.
How do you ensure accessibility (a11y) in a frontend application?
Follow semantic HTML practices, use ARIA attributes when necessary, ensure keyboard navigation, and test with screen readers. Tools like Lighthouse can help identify issues.
What testing strategies do you use for React applications?
Use Jest for unit testing and React Testing Library for component behavior testing. Focus on testing user interactions and expected outcomes rather than implementation details.
How do you improve SEO in a Next.js application?
Leverage SSR/SSG, use proper meta tags with next/head, optimize images, and ensure fast loading times. Structured data and accessibility also contribute to better SEO.
How do you monitor and debug frontend performance in production?
Use tools like Grafana, browser DevTools, and Core Web Vitals metrics. Logging, tracing, and real user monitoring (RUM) help identify and resolve performance bottlenecks.
