Frontend Developer - 2026-36151

Department Head quarters: Tech & Data

Education level: Higher professional education

Contract hours: 32-40

Job description

As a Senior Frontend Developer in the ICX team, you directly contribute to the digital customer experience in Jumbo stores. The ICX team develops the software that runs on hundreds of screens and kiosks in our stores—from smart checkout applications to interactive customer displays. Are you a frontend specialist who writes beautiful, high-performance, and maintainable code while also bridging the gap to backend systems? Then we’re looking for you.

Working at Jumbo Tech means being part of an international, agile team where English is the working language. You’re not the type to sit quietly in a corner: you ask questions, share your insights, and easily connect with colleagues. You work with modern tooling, TypeScript, a monorepo setup, and GitHub Actions for CI/CD, and you fully understand how the frontend communicates with REST and GraphQL APIs.

You’ll be part of a Scrum team where everyone takes ownership. Two-week sprints, short feedback loops, and continuous improvement—that’s how we work. Do you also have an affinity with Node.js or MongoDB? That’s a plus—you’ll be able to support our backend engineer Sergei whenever needed.

• Strong communication skills in both Dutch and English; within the international team, English is the primary working language.
• Proactive mindset: comfortable speaking up, asking questions, and actively seeking collaboration rather than waiting.
• At least 5 years of relevant experience with a modern frontend framework; preference for Vue, but solid experience with React is also welcome.
• Advanced knowledge of TypeScript and the ability to write type-safe and maintainable code.
• Understanding of backend architectures and experience integrating REST and/or GraphQL APIs on the frontend.
• Experience with CI/CD pipelines, preferably using GitHub Actions.
• Familiarity with working in a monorepo environment and understanding of its associated challenges and benefits.

Nice to have

• Affinity with taking a leading role in Scrum ceremonies, such as facilitating sprint planning sessions, retrospectives, and refinements.
• Knowledge of Node.js and/or MongoDB, enabling you to support the backend engineer during peak workloads or complex challenges.

• You build robust frontend applications in Vue or React, work with TypeScript in a monorepo setup, build bridges to backend teams via REST and GraphQL, and actively contribute to a strong CI/CD culture through GitHub Actions.
• The ICX team develops Jumbo’s digital in-store customer experience. Your work directly impacts millions of customers: faster communication, smarter screens, better in-store data—all powered by the code you write.
• You work in a close-knit, international Scrum team. English is the working language. You’re not on your own: colleagues expect you to ask questions, think along, and share your knowledge. Together, you deliver user stories end-to-end in short sprints.
• You collaborate closely with backend engineers (including Node.js/MongoDB), designers, a Product Owner, and stakeholders. You take initiative, even beyond your own part of the code.
