We are seeking a UX Design Intern to join our fast-growing Platform Team for 6 months in a full-time capacity. The targeted start date is April 2026 and since we value long-term growth, exceptional performance during the internship may lead to an offer for a permanent role. In this role, you'll help design and develop intuitive user interfaces for our quantum sensing systems, bridging the gap between cutting-edge hardware technology and user-centric software design. Your work will enable semiconductor engineers to interact seamlessly with our advanced metrology tools, making complex data visualization accessible and actionable. This internship is an opportunity to work hands-on at the intersection of design, software development, and cutting-edge quantum sensor development.

QuantumDiamonds is one of the world’s most advanced deep-tech companies, developing quantum-sensing systems that redefine electrical fault localization and yield engineering in modern semiconductor manufacturing. Our technology visualizes current paths inside highly complex multi-layer packages, enabling engineers to understand, debug, and optimize next-generation devices faster and with unprecedented precision.

Backed by leading international investors and major public innovation programs, we are entering a high-growth phase as we prepare to ship our first series of devices next year. Headquartered in Munich, Germany, QuantumDiamonds works closely with leading semiconductor manufacturers across Asia, the US, and Europe on the future of HBM, chiplets, advanced fan-out, and system-level integration.

Picture this:

• A machine that catches what others miss – in milliseconds.
• Physics, data, and engineering are working hand in hand to build tools that matter.
• An international team, who loves solving hard problems and where knowledge flows fast.

Still unsure about why joining us?

• You'll get to build a company together with a brilliant and welcoming team on a product that has never been done before.
• Our technology is the cutting edge of tomorrow, starting today and not in 10 years.
• You will work directly with major semiconductor companies from Day 1.
• You’ll be part of a high-growth company backed by top-tier investors.

Let’s make the invisible visible!

• Design intuitive user interfaces and user experiences for our quantum sensing software platform using Figma.
• Collaborate with engineers and physicists to translate complex technical requirements into user-friendly workflows.
• Develop and implement UI components using Python and Qt framework, bringing your designs to life.
• Conduct user research and usability testing with internal teams and external customers to iterate on designs.
• Create design systems, wireframes, prototypes, and visual assets thatmaintainconsistency across our product suite.
• Work closely with the ML and engineering teams to visualize complex data and simulation results effectively.
• Contribute to documentation, version control (Git), and collaborative design workflows.
• Learn about the unique challenges of designing interfaces for scientific instrumentation and deep-tech products.

• You are willing and able to join us for 6 months starting April 2026 in full time.
• You are a student or recent graduate in Interaction Design, Human-Computer Interaction, Computer Science, or a related technical field.
• You have demonstrated experience with Figma and UX/UI design principles (portfolio required).
• You have basic programming knowledge or willingness to learn Python and Qt framework for UI development.
• You are eager to bridge design and development, learning how to implement your designs in code.
• You bring a user-centered design mindset with attention to detail and visual aesthetics.
• You have strong communication skills and enjoy working closely with technical teams.
• You bring a hands-on, proactive mindset and enjoy solving complex user experience challenges.
• You enjoy working closely with a multidisciplinary team on-site in Munich.

• Mission: At QD, we’re driven by more than just building great products - we aim to make a lasting difference. Joining us means contributing to meaningful work that goes beyond business as usual.
• Impact & growth: This is an exciting stage of our journey, and your voice matters. You’ll have the chance to shape our culture, influence key decisions, and grow alongside a company that’s scaling fast.
• Health & fitness: With a company-sponsored Wellpass membership, you’ll have access to countless gyms, classes, and wellness offers across Germany to stay healthy and active.
• Team & culture: We believe the best ideas come when we connect outside the office. From regular off-sites to team events, you’ll be part of a collaborative and supportive environment.
