We're looking for a Senior Frontend Developer to join an international product team, working 24–32 hours per week (3–4 working days) .

This is a hands-on role for someone who enjoys taking ownership, making technical decisions, and being an active part of a product team.

About the Client
Our client is a Netherlands-based software partner delivering enterprise-grade software solutions. From custom web applications to complex integrations, they turn business challenges into efficient, high-quality software solutions.

?? About the Role
As a Senior Frontend Developer , you will take ownership of the user-facing side of business-critical B2B applications, with a strong focus on Vue.js. You’ll work closely with backend engineers, product stakeholders, and a Product Designer based in Australia to translate complex commercial and logistical processes into intuitive and reliable digital experiences.

We're looking for someone who can take ownership of frontend development , contribute to technical decisions, and proactively drive improvements rather than simply work through assigned tasks.

This is a long-term engagement of 24–32 hours per week, ideally across 3–4 full working days . You'll need to be available during regular CET working hours, including daily stand-ups and team meetings.

We're looking for someone who can make this project a priority, rather than fit it around an existing full-time job as a side project.

?? Responsibilities

• Design, build, and maintain robust Vue.js applications for B2B users
• Translate complex commercial and logistical business logic into clear, intuitive interfaces
• Collaborate closely with backend engineers working with Laravel on API design and contracts
• Work with Product and Design to turn requirements and designs into high-quality user experiences
• Contribute to and help evolve a shared component library and design system
• Ensure strong frontend performance, accessibility, and cross-browser compatibility
• Write maintainable, scalable, and well-tested frontend code
• Communicate clearly and proactively in English with global stakeholders, both technical and non-technical
• Take ownership of your work and contribute to the ongoing reliability of the platform

?? Tech Stack

• Styling : Modern CSS, component library / design system driven
• Backend (context) : Laravel, REST APIs

? Requirements

• Senior-level experience with Vue.js, ideally Vue 2 and 3 and the Composition API

• Solid understanding of REST API consumption and state management at scale
• Comfortable working alongside a Laravel backend; hands-on PHP experience is a plus
• Experience with front-end testing
• Experience with build tooling, CI/CD pipelines and front-end performance optimisation
• Familiarity with Docker and modern development environments
• Proven experience working in a distributed, international team across multiple time zones
• Professional-level English, written and spoken, at a level that allows you to lead calls, write documentation and discuss complex topics with confidence
• Strong communication skills are essential and weigh as heavily as technical ability in this role
• Ability to explain technical challenges clearly to non-technical stakeholders
• Proactive, reliable and ownership-driven mindset
• Availability for 24–32 dedicated hours per week, including daily stand-ups and regular collaboration during CET working hours
  

?? What We Offer

• A long-term, part-time engagement (24–32 hours per week)
• A fully remote role
• A key role with real ownership of frontend development
• The opportunity to influence frontend architecture and technical decisions
• Collaboration with an experienced international product and engineering team
