We are looking for experienced developers who thrive in a dynamic environment, enjoy solving complex problems, and want to be part of a team where innovation and collaboration drive success. As a key player in our development team, you will help shape our platform, improve our architecture, and ensure that we continue to deliver high-quality solutions to our growing user base.


What is Unioo?

Unioo is a software company that has developed a board and compliance tool that does two things:

  • It helps Danish financial institutions collect legally required data about their association customers

  • It helps volunteer associations throughout Denmark manage their board work and their members.


We specialize in digital security in this area and are dedicated to helping enthusiasts in all corners of Denmark. We have built this passion through spending a lot of time in volunteer associations ourselves. Currently, we have more than 25 financial institutions on board and many thousands of associations, and we can see that it's going to be a lot more fun with a lot (!) more very soon! Everyone on the team always comes up with good (yes, sometimes brilliant!) ideas for further development of the system and the company in general, and we place great emphasis on ensuring that each employee has the opportunity to pursue their ideas, develop further, and have good opportunities for continuous skill improvement.


Why join Unioo?

  • You get a level of responsibility based on qualifications

  • Flexible working hours - we take work/life balance seriously

  • We take your development ideas seriously and are open to your input

  • You become part of a scaleup company and can influence the development of everything from individual products and procedures to the work culture in general

  • We have a lunch arrangement with a daily walk afterward (paid lunch break), as well as coffee and tea ad libitum

  • We organize small and large events with fun and delicious food and drinks

  • We have the coziest office in Randers with a good down-to-earth atmosphere

  • A good working environment with room for diversity, big gestures, and good humor

  • We provide space for focus and development

  • We foster a culture of continuous learning and knowledge sharing to keep everyone engaged and growing.


Who are you?

  • You are motivated to develop the core product for a tech startup, where your skills, together with those of other developers, help drive the company forward and take everything to the next level.

  • You can balance deep technical development with being an accessible sparring partner for the rest of the team when it comes to development and quality, support, idea development, and motivation.

  • You focus on strategic planning so that what is developed and time is spent on now is as sustainable as possible in the long term.

  • You should be ready to handle and improve Unioo as the system is now, as well as take responsibility for developing new features.

  • You should be passionate about a startup culture where not many processes are fixed yet, where there is ongoing change (especially in the beginning), and where everyone contributes openly.

  • You thrive in an environment where feedback is encouraged, and cross-functional collaboration is key.

  • At the same time, you should be structured and write high-quality code that ensures security, scalability, and compliance with banking and financial industry standards, in Denmark and abroad.

  • We are not looking for fully remote developers, but you can work from home a few days a week.

Education

If you have an education as a computer scientist or computer engineer, that's fantastic, but as long as you are good at what you do, the education is secondary. If you have a portfolio in software and development, we would like to see it.


Salary and start date

Salary and start date is agreed upon based on conversation. It would be fantastic if you can start as soon as possible, but we will be looking for the right candidate!


Are you interested?

We hold ongoing interviews, so feel free to send your CV and a short description of yourself and why you think we are a good match.

Working at
Unioo

Unioo is building a digital compliance and board management platform to help financial institutions and voluntary associations handle complex regulatory reporting—simply, securely, and without friction. 1. What problem are we solving? Associations in Europe are required by law to submit complex KYC and AML documentation to their financial institutions. This process is often confusing, paper-based, and time-consuming—especially for small, volunteer-run associations. At the same time, banks are struggling to comply with increasingly strict regulations without overloading internal teams or alienating nonprofit customers. 2. How are we solving it? Unioo provides a secure, plug-and-play digital platform where associations can easily complete their mandatory bank reporting. At the same time, they gain access to a suite of free digital board tools—meeting management, task tracking, file sharing and more. Banks receive fully compliant data packages with no internal resource strain. Associations stay compliant while benefiting from better tools for managing their boards. 3. Why are we doing this? We started Unioo as volunteers ourselves. We saw how much time was wasted on outdated processes, and how legal changes (like AML) were turning volunteer work into a bureaucratic burden. Then we realized: we could help both associations and banks by offering one unified solution—tailored for the unique needs of volunteer boards and aligned with financial institutions' regulatory requirements. 4. Why join us? We’re a fast-growing Danish startup backed by strong investors, trusted by 25+ financial institutions, and used by thousands of associations. Our team is small but ambitious—and deeply motivated by the impact we make. If you’re excited about simplifying bureaucracy, building elegant solutions, and empowering civil society, we’d love to meet you.
