Join the team that brings social change through coding.

Here’s your chance to work only on projects that positively impact the health and lives of others. And to do it in a place that values innovation over efficiency. Do you take it?

We’re looking for a great developer. Someone who is creative and can see conceptual patterns that others can’t—a person with an eye for detail and an adjustable perspective. When stuck in a set way of thinking, you’re finding ways to push, pull, and prod yourself to look beyond. When any support is needed, you know you can count on the rest of your teammates.

Are you in?

🍎 a Senior iOS developer with...

  • Basic knowledge of RxSwift. Plus, you are familiar with Xcode/Appcode, Instruments.

  • Experience in using various software architecture patterns.
  • Fluent English-speaking skills (you would participate in regular calls and meetings with our English-speaking partners).
  • Speaks and writes Polish fluently.

So, what’s the process?


Everything starts with a conversation. You’re taking the time to send an application, so (based on your CV), we’re doing our best to assess your skills. Should we have doubts, we will reach out to you so you can go into more detail about your experience.

Intro call

Let’s talk/human/conversation. During a 15-30 min casual phone chat, we want to give you an overview of the company (and the role) + get to know you as a person. Are we a good fit for each other?

Technical task

Show you’ve got what it takes. U may be asked to fulfill an additional task. (we’ll let U know during the intro call). The assignment is strictly related to your role. The aim is to confirm (to you and to us) that you’re the right fit.


Let’s get into details. During a 1-2 hours online video meeting (cameras on), we get to actually interact! Expect to meet your potential team members, pair programming (for technical roles), and hear questions related to your role. And hey, it's a safe space for honest feedback.


Congrats! You made it to the final step. You know everything there is about your role. Both Uk and UK are confident you are a great fit. Now, it’s your decision. Change starts with U.

Whatever you do, do it with passion.

Bartek, iOS Developer

"The best thing about Untitled Kingdom is the 3 core values of the company: Quality, Family, and Transparency. Especially transparency. It doesn’t matter if it’s good or bad news; I feel comfortable knowing that important information will be disclosed to the whole UK Family. The way we communicate here is quite special. There’s no sugar coding, and no one is left in the unknown."

All for now, yet it’s just the beginning
