Are you excited about working on a modern, state-of-the-art platform used by a large number of customers on a daily basis? Then you might be the person we’re looking for!

About Mijndomein

At Mijndomein, we build and operate an international, high-traffic and high-availability digital platform used daily by a large number of customers. Our technology powers e-commerce, billing and content management systems and is designed with scalability, reliability and quality at its core.

Mijndomein is part of The Sharing Group, a Dutch family-owned group of technology companies focused on long-term value, quality and positive societal impact. We work in an open, people-centred culture where collaboration, ownership and continuous improvement are key.

The Role

As a Senior Full Stack Engineer, you will join one of our multidisciplinary engineering teams and work on our core, customer-facing platform. This platform supports our e-commerce, billing and CMS systems and is built to scale across multiple markets.

You will be part of a full-stack Scrum team, translating requirements into high-quality, maintainable solutions. You collaborate closely with fellow engineers and other departments across the organisation. Operating in a competitive and fast-moving market means adaptability and curiosity are essential.

Our platform serves customers across multiple countries and regions, so you will work with internationalisation, localisation and region-specific requirements. The team is distributed across multiple countries and works comfortably in a remote-first setup. At the same time, we value in-person collaboration and creativity, which is why we ask you to join us at our Almere office at least one day per week.

What you will do

You contribute to building and maintaining a high-traffic, high-availability platform. You collaborate with other engineers on scalable and reliable solutions. You translate functional and technical requirements into clean, well-structured code. You actively participate in code reviews, pair programming and continuous improvement of the codebase.

You enjoy working with modern technologies and architectures and like to experiment with new approaches. AI plays an important role in your daily workflow, whether for prototyping, improving code quality or working more efficiently. You help promote an AI-first mindset within the team, while maintaining high standards for quality, performance and maintainability. You challenge existing choices, propose new ideas and contribute to the growth of both the product and the team.

What we offer

We offer a challenging role within an international and technically mature organisation. You will work with experienced colleagues in an open and informal culture where initiative and new ideas are valued. We work in a hybrid setup with plenty of flexibility, while asking for at least one day per week at our Almere office. In addition, we offer a competitive salary, solid secondary benefits, room for personal development and the opportunity to work on a platform with real scale and impact. As an employee, you automatically earn Share Points, which can be converted into Good Shares. This way, you become a small part owner and share in the success we build together.

Who you are

You are a team player who enjoys collaboration, takes initiative and embraces responsibility. You like being challenged and challenging others in a constructive way. You are analytical, curious and stay up to date with developments in the field. You are comfortable working in multidisciplinary teams and use a critical mindset to continuously improve yourself and the team. You communicate clearly and feel at home in an international working environment. Your English is at an advanced or native level.

Your experience

You have strong experience with Node.js and TypeScript, React or another modern frontend framework, and digital e-commerce platforms. You are familiar with AI-powered code editors and models, event-based architectures and microservices. You have worked with Docker and Kubernetes, GraphQL, RabbitMQ and SQL.

Experience with Java, Medusa JS, Payload CMS, Kill Bill, Next.js (App Router), Tailwind CSS and modern CSS is considered a plus.
