Job description

JOB PURPOSE

We’re looking for a Frontend Developer who thrives on translating high‑fidelity designs and clear acceptance criteria into polished, performant, and accessible digital experiences. At DEPT®, your work will directly shape the frontlines of global digital platforms — where visual excellence, responsiveness, and accessibility matter. You’ll work alongside multidisciplinary teams to create frontends that meet today’s standards and tomorrow’s expectations.

WHAT YOU 'LL DO

• Translate tickets and acceptance criteria into functional, testable components using React, Tailwind CSS, and TypeScript.
• Build interfaces from Figma designs with high visual accuracy and attention to pixel perfection.
• Develop responsive layouts and components that adapt elegantly across devices and breakpoints.
• Ensure all components are accessible and inclusive, meeting WCAG 2.2 AA compliance standards.
• Optimize UIs for Core Web Vitals (LCP, CLS, INP) and other performance metrics.
• Contribute to and maintain shared component libraries and frontend standards.
• Collaborate with designers, QA, and backend developers to validate requirements and ship features.
• Follow clean coding practices like DRY, KISS, and component reuse to keep the codebase scalable and maintainable.
• Great to have: Working knowledge of Framer Motion, GSAP, ThreeJS, or other animation frameworks.

WHAT YOU BRING

• 5+ years of experience building frontend applications, preferably in agency or multi‑project environments.
• Fluency in React, Tailwind CSS, and TypeScript, with strong attention to detail and usability.
• High working proficiency in both Dutch and English.
• Knowledge on how to bring Figma designs to life, down to the last pixel — but know when perfection gives way to pragmatism.
• Ability to build fully responsive UIs that look and behave well on all modern devices and browsers.
• Understanding of optimisation for Core Web Vitals and real‑world performance benchmarks.
• Ability to apply WCAG 2.2 AA standards — including semantic markup, keyboard accessibility, and visual contrast.
• Passion for UI quality, maintainability, and collaborating with designers and backend engineers.
• Application of clean code principles like DRY, KISS, and modularity to your work.
• Clear communication and contribution to a healthy, collaborative team dynamic.

WE OFFER

• A flexible, hybrid working policy (2‑3 days from the office, depending on location) and the opportunity to work from abroad for 13 weeks a year.
• 24 vacation days per year and the possibility to buy an unlimited number of extra vacation days.
• DEPT®/YOU Learning Menu and DEPT®/YOU Special Programs. Develop your skills with courses and programs tailored to your needs.
• Stay happy and healthy with a contribution to your health through the OpenUp platform, gym and wellness discounts, and healthy lunches at the office.
• Awesome clients. Whether big or small, local or global — at DEPT® you’ll get the opportunity to work with clients of all sizes and across all industries.
• The opportunity for possibility. We want to enable you to do what you do best and help you develop your skills further with training, development and certifications.
