At OpenProject, we build open-source project management and collaboration software used by organizations around the world. We believe good software does not begin with mockups or code, but with an understanding of people’s needs. Our users rely on our product to collaborate in agile product teams delivering software, plan infrastructure projects, organize research programs, and coordinate complex work across multiple teams and projects within enterprises. Our users build rockets, cars, or software using OpenProject and we are proud to empower teams worldwide to achieve great things together.

We are looking for a Senior UI/UX Designer to join our user-centric design team and help shape the future of OpenProject.

You will work closely with product managers, engineers, QA and marketing to collaboratively improve our product. Sometimes this will mean working on a completely new feature idea that expands the scope of OpenProject and other times refining an existing interaction that thousands of users already rely on. As a designer, your goal is to iteratively improve things with every release.

Your mission

You collaborate in a product trio (product management - engineering - design) in order to understand users’ needs and their use cases. We start with the problem and opportunity, try to understand it well and move on to the solution space. You will guide the process from UI/UX perspective from early discovery to polished implementation. In your daily tasks you will:

• Conduct user research, both exploratory discovery work and usability testing.
• Translate research insights into clear concepts.
• Design high-fidelity mockups on Figma.
• Iterate on ideas based on feedback from users, engineers, product and QA.
• Work closely with engineers to ensure designs translate well to the realities of implementation.
• Help maintain and evolve our design system by creating and documenting components and patterns.
• Update and redesign existing parts of the software in need of improvements.
• Balance ideal UX with technical constraints, product strategy, and delivery timelines.
• Contribute ideas that help improve the overall experience of OpenProject., * You will work with a team of experienced software engineers in continuous delivery and integration processes who love to learn from each other.
• Once a year, we dedicate our “Passion Time” off-site to work on any improvements of our choice with a business impact (e.g. product improvements, marketing concepts,…) in multi-disciplinary teams.
• Employee benefits such as job bikes and paid child care.
• You will be in touch with exciting clients and users from all around the globe, including NGOs and other open source projects which we love to support in fulfilling their mission (such as Greenpeace, Engineers without Frontiers), corporates like Siemens, Deutsche Bahn or Audi and public institutions like German Federal Ministries.

• Solid UI/UX design experience working on complex digital products.
• Experience conducting user research and usability testing.
• Strong skills in developing concepts, design iterations, and high-fidelity mockups in Figma.
• Experience collaborating closely within a cross-functional product team (engineering, product management, QA, marketing and sales).
• Experience maintaining or contributing to a design system.
• The ability to balance ideal UX, technical realities and practical delivery.
• A pragmatic mindset and the habit of improving things iteratively.
• A thoughtful, creative, curious, and communicative team player.

Experience with open-source projects and familiarity with distributed Git-based version control systems such as GitHub or GitLab are a plus but not required. What matters most is curiosity, judgement, and a genuine interest in how people use software.

At OpenProject, we build open source project management software that helps teams plan, collaborate, and deliver work more effectively. We believe great software should empower people to organize work in a way that supports autonomy, accountability, and collaboration across boundaries.
