UI/UX Designer (Werkstudent)

ONLY APPLICANTS AVAILABLE TO WORK IN KARLSRUHE

Working Student / Mandatory Internship – UI/UX Designer with C++ Implementation Skills (m/w/d)

We are looking for a UI/UX Designer to join VISS as a Working Student or Mandatory Intern in an on-site role based in Karlsruhe.

VISS is building a new hardware-based cybersecurity layer that physically isolates untrusted digital content before it can reach protected systems in executable form. As part of our team, you will help shape the user experience, product interfaces and visual identity of a deep-tech cybersecurity startup working at the intersection of hardware, software, security and design.

This is not a purely conceptual design role. We are looking for someone who can not only design intuitive interfaces, but also help implement those designs directly in the product environment, especially in C++-based UI development. Support from the development team is available, but only selectively, so you should be comfortable working independently, close to the code, and iterating quickly.

Your responsibilities

You will apply design thinking methods to create intuitive and user-friendly experiences for our product and internal tools. You will work closely with our engineering and marketing teams to design, prototype and implement user interfaces that are functional, visually clear and aligned with real user needs.

Your tasks will include:

• Designing intuitive UI/UX flows for hardware and software interfaces
• Creating wireframes, mockups, clickable prototypes and design systems
• Implementing UI elements and prototypes in C++
• Adapting and improving existing product interfaces
• Designing concepts for keyboard/mouse-operated and touch-operated interfaces
• Supporting website, brand, logo, merchandise and marketing asset design
• Contributing to brand guidelines and visual identity
• Collaborating with engineering to translate designs into functional interfaces
• Improving product usability based on user feedback, technical constraints and business goals

Your profile

You are currently studying design, media design, interaction design, human-computer interaction, computer science, software engineering or a related field.

You combine a strong design mindset with enough technical understanding to bring your concepts into the product. You should have a good eye for detail, a sense for usability and the ability to work hands-on in a fast-moving startup environment.

Ideally, you bring:

• Experience with UI/UX design, interaction design or product design
• Experience with AI Tools
• Experience with Figma or similar design/prototyping tools
• Basic to solid experience with C++
• Interest in C++-based UI development
• Ability to independently implement interface elements with occasional developer support
• Understanding of design systems, usability and user-centered design
• Interest in cybersecurity, hardware, deep tech or critical infrastructure
• A proactive, structured and hands-on working style
