Senior Frontend Developer

This role is part of the Engineering Department in Amsterdam, Netherlands. You will be working with an ambitious team of experts in delivering innovative solutions to our clients, such as Meijers, Muuto and many more.

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.

KEY RESPONSIBILITIES

• 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.

WHAT WE ARE LOOKING FOR

• 4–7 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.
• 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

• Holiday allowance
• Pension scheme
• Internet allowance
• Hybrid working model
• Flexible working hours
• A reputation for doing good. DEPT® has been a Certified B Corp® since 2021 and named ‘Agency of the Year’ at both The Lovies and The Webby Awards.
• 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. And we celebrate all of our successes together!
• 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.
• Global annual DEPT® Cares Month in which employees come together and donate their skills to support local charities
