Full-time · Amsterdam

Koos works for clients all over the world, with offices located in Amsterdam, Lisbon, Berlin, and most recently Oslo. We collaborate with various organisations and companies to develop their products and services and support them tackling innovation challenges. As our digital division is growing fast, we are looking for a skilled Medior or Senior digital product designer to join us in the pursuit of making digital products more human!

Your challenge

Are you passionate about making a positive impact through digital products? Do you want to develop yourself by working on diverse complex design projects worldwide - both in terms of hardcore UX skills and strategic innovation skills - and further develop as a rock-solid digital product designer? Then this role is tailor-made for you!

As a Medior or Senior UX Designer, you will take the lead in running projects while guiding junior team members. Together, you will design rock-solid, user-friendly digital products. Products that not only make sense on all sides, but are also visually attractive. In addition, you are strategically strong and sensitive to the organisation you are working for. In your design process, you maintain a holistic perspective, considering the complete service and all touchpoints. You are assertive in engaging various stakeholders (from C-level and PO to developers and privacy experts), and facilitate the team in strategic decision-making. With a toolkit of design methods and tactics at your disposal, you know which tools to employ to drive progress in your design process.

While thought leadership is not mandatory, we highly encourage it! If you have a passion for motion, digital accessibility, or design systems and aspire to develop yourself further while sharing your expertise with the Koos team and the wider community, there is ample opportunity to do so.
