Senior Frontend Engineer (React / Next.js)

Our Customer a company founded in 2019 that works exclusively with international customers. Despite our young age, we already have a portfolio of long-lasting clients and are proud of the results we’re bringing to their businesses.

We’re a team of experienced and senior tech professionals with Danish management and a passion for building things right. Our clients are well-established organizations with a serious approach to Technology and Digital products. They strive for best-in-class experiences — and that’s what we deliver.

We strongly believe in modern architecture based on MACH Alliance Principles: Microservices, API-based, Cloud Services, and Headless.

What You’ll Do

Build a new frontend from the ground up using modern tooling — fast, broadly compatible, and UX-focused — and integrate it seamlessly into our existing e-commerce platform.
Participate in frontend development from discovery through launch, ensuring continuous improvement throughout the entire product lifecycle.
Collaborate proactively with stakeholders and teams to build a common understanding of solutions that address business and customer needs.
Take ownership of your work and act as a co-owner of the project. Take initiative and responsibility, share your thoughts, concerns, feedback, and advice to help us build better solutions.
Stay curious and keep up with trends in design, technology, and user experience. Share what you know and make an impact.

What We’re Looking For

5+ years of experience in frontend development — although if you have less, prove us wrong :-)
Strong knowledge of JavaScript (ECMAScript 5–7) and TypeScript.
Proficiency with ReactJS, including Hooks, Context API, core principles, and ecosystem.
Hands-on experience with Next.js.
Strong knowledge of HTML5, including semantics, DOM, adaptive and responsive development.
Strong knowledge of CSS3/SASS, CSS Modules, and cross-browser compatibility.
Experience with frontend build tools such as Webpack.
Experience with Git and unit testing with Jest.
Experience optimizing and developing fast-loading websites, including content caching and pre-loading asset optimization.
Familiarity with Agile methodologies such as Scrum and Kanban.
Strong spoken and written English — you should be comfortable gathering project requirements, participating in workshops, and clearly explaining your design and architecture decisions.
