About the Role:

We are looking for an enthusiastic front end developer specialiced on Vue 3 to join our team in evolving Frontiers' publishing web. The platform is large and complex, combining both modern and legacy technologies. This role involves maintaining and improving existing systems built with older technologies while contributing to the gradual transition toward a more modern and scalable architecture.

Your focus on best practices, collaboration, and continuous improvement will be essential in driving the platform's success. If you enjoy working with both existing and new technologies in a dynamic environment, we'd love to hear from you!

Requirements

Experience

  • 4+ years of professional frontend development experience
  • Strong experience building production web applications with Vue and Node-based frameworks (ideally Nuxt 3; similar experience with Next.js is also relevant)

Responsibilities

  • Build and maintain SSR-first web applications using Nuxt 3
  • Implement pages, layouts, and reusable components with strong UX and accessibility practices
  • Integrate frontend applications with backend APIs (REST/GraphQL), handling authentication and error states
  • Work with data-heavy features (search, filtering, pagination) and integrate with services such as Elasticsearch and MongoDB-backed APIs (through backend endpoints)
  • Contribute to frontend architecture and standards (project structure, composables, state management, code conventions)
  • Improve quality and delivery through code reviews, refactoring, testing, and debugging production issues
  • Collaborate with QA, DevOps, and product teams to ship, monitor, and troubleshoot releases
  • Contribute to technical improvements: performance, observability, maintainability, developer experience

Must-have technical skills

  • Vue 3 + Composition API in production
  • Nuxt 3 with SSR in production (routing, layouts, server routes if used, SSR vs CSR trade-offs, runtime config)
  • Pinia in real-world apps: store design, SSR compatibility, state serialization, and testing
  • TypeScript (strong practical usage, typing components/composables, avoiding any)
  • Solid HTML/CSS fundamentals (responsive layouts, modern CSS, cross-browser)
  • Comfortable consuming APIs and handling client-side data flows (loading/error/empty states)
  • Familiarity with Git workflows and code review practices
  • Clean code mindset: maintainable architecture, naming, separation of concerns (SOLID principles applied pragmatically)

Nice-to-have

  • Nuxt modules ecosystem, Nuxt server routes, or BFF patterns
  • Testing: unit/component testing (Vitest/Jest), e2e (Playwright/Cypress)
  • Performance optimization: hydration/SSR performance, caching, bundle analysis, lazy loading
  • Observability: error tracking (Sentry), logging/metrics, web vitals
  • Docker familiarity and working in CI/CD environments
  • Experience using AI coding agents like Claude, Chat GPT, Copilot, etc.

Soft skills

  • Team player; collaborates well across roles
  • Comfortable giving and receiving constructive feedback (code reviews)
  • Proactive learner; adapts to new tools and requirements
  • English communication: can clearly explain technical ideas in writing and calls (doesn't need to be perfect)

Benefits

  • We prioritise office presence and emphasise in-person collaboration, but also offer appropriate adjustments where needed, in line with company policy
  • Extra wellbeing days on top of your annual leave allowance
  • Up to 3 paid volunteering days each year
  • 24/7 confidential Employee Assistance Programme (wellbeing, mental health, legal & financial support)
  • Learning & development support via the Frontiers Learning Hub
  • Competitive local benefits country dependent (e.g. healthcare and pension/retirement provision)
