Product / UI Designer

Let's rethink tomorrow

Hi, we are dayy.

dayy® is an experience design agency in the heart of Cologne, founded in 2016, with a team of around 20 people.

We craft forward-thinking digital products, brands and experiences for a more exciting, joyful and resilient tomorrow.

The brands we work with, e.g. Red Bull, Spotify, Rewe and Allianz, appreciate our way of working and our idea of being their partner in crime rather than your regular service provider.

We are really serious about the work we do and the quality we deliver but we are also very serious about having fun at work and not taking ourselves too seriously.

And one more important thing before you read the following:

We know job postings can be pretty intimidating. We don’t expect you to be or to have all the requirements listed here. No one can be an expert in everything. You are specialized in one field but got a general understanding of the rest and willing to learn and improve? Perfect! Give it a Go!

Our Beliefs

People first.

Because that’s what we all are, aren’t we? In a digital world we should never forget what it means to be human. We are empathetic and strongly believe that a successful experience always starts by focussing on the user’s context. But it does not stop there: We as a team and also our clients are humans, too. That’s why we have the interests and needs of everyone involved at heart, when it comes to tough decisions.

Driven by Story & Vision.

Because everybody loves a good story. A commitment to compelling storytelling is a red thread through all our work. It breathes life and passion into every project.Technology can send us flying to our destination, but we need the navigation of vision and story to get us anywhere worthwhile.

Design with Soul.

Because it’s in the details. Every project deserves passion and dedication, and we leave a bit of ourselves in each one. Our ambition always is to honor the craft and create tangible, beautiful and exciting things that have an emotional heart and go beyond being just functional.

There is no boring.

Because the point is to find wonder in everything. We believe everything can be exciting. It’s just a question of „how“. Through story, joy and ease we aim to create meaningful experiences that provoke a sense of wonder and delight. Our goal is to move & excite people with everything we do.

Less noise. More action.

Because we do, rather than just talk. We like to roll up our sleeves and dive in. We don’t believe in endless powerpoint decks and meetings. Flexibility is key, as is quickly adapting to new conditions and challenges. Like a living organism we react to the ever-changing circumstances we face while doing project work in realtime.

Power of together.

Because it’s all about teamwork. We are not just another service provider where checking in feels like more of a chore. We prefer to see ourselves as your partner in crime. And just like any good relationship, collaborating with us should take place on eye-level, based on honest communication & transparency. We love to work as integrated teams. As equals we strive towards the best possible result - together.


Culture Check – that is how we roll.
Rolling with us?

  • We don’t have an agency dog yet, we would love to have one though. Or even better, an agency lama, yes lama.
  • Things can get chaotic but we never lose sight of the real important stuff.
  • We love to take the team to our favorite restaurants for team meetings and things like that. Combine work with something pleasant.
  • We love to have some fun side projects like our own dayy Merch, our own clothing line and potentially our own dayy Café.
  • We really enjoy the time we are together as a team in our office but working remote has almost become the standard. So if you live in a different city, that is totally fine with us. We would like to have you here in Cologne though once in a while for certain meetings, team events, etc.
  • We like Memes and we are not afraid to use them.
  • That also applies to cringy Dad Jokes.

What’s happening Next?

  • Send your CV and portfolio to and just drop a few lines on yourself that is not written in your résumé (no need to google „professional cover letter“)
  • Let us know when you could start and what your salary expectations are
  • We will contact you and best case arrange an interview with you
  • If you don’t hear from us within a week, feel free to reach out to us
