Descripción del empleo

Senior UI/UX Engineer- Quantum Computing (f/m/d) at eleQtron, Siegen, Nordrhein-Westfalen, Germany. A senior-level full time position in the Quantum Firmware team, listed under software engineering.

We are looking for a Senior UI/UX Engineer (m/f/d) to join us in Hamburg or Siegen and own the end-to-end experience of working with our quantum computers, from the customer-facing web platform for submitting quantum programs and exploring results to the internal interfaces used to run, monitor, and calibrate our machines in the lab. You set the design direction for both, and you build the component library that both are made of.

This is a design-led role for someone who is not satisfied handing over a Figma file and hoping for the best .

• Flexible working hours : We offer personal freedom through a variety of flexible work schedules
• Team spirit: In our international and diverse team, and with our regular team events, having fun at work is simply part of the culture
• Further development: We want to grow together and so we offer our team members needs-based, individualized further training as well as plenty of room for personal development

• At the forefront : Work at the forefront of technology, where academic research meets commercial applications
• Modern workplace: We have a high-quality infrastructure with laboratory space, offices and meeting rooms

Responsibilities

• Own the design direction for our customer-facing cloud platform and our internal operator interface, and keep them coherent as one product family
• Run the research: interview operators and physicists, observe real calibration workflows in the lab, and turn what you learn into design decisions
• Produce wireframes, interactive prototypes, and high-fidelity designs for both surfaces
• Build and own our design system as production-ready, tested components in code — the shared foundation that our engineers assemble applications from
• Make dense telemetry and calibration data legible: define the visualisation patterns that let operators see what matters at a glance
• Validate what ships: run usability tests on implemented interfaces and hold the quality bar between design intent and delivered product
• Shape APIs together with backend and platform engineers, advocating for the user's perspective early in the process
• Set the standard for accessibility, usability, and visual consistency, and raise the design literacy of the wider engineering team

Requirements

• 5+ years of professional experience in product or interaction design, with a portfolio of shipped digital products
• Ability to build your own designs as reusable components in production code: confident with TypeScript and React, including component testing and documentation (e.g. Storybook)
• Mastery of the full design toolkit — research, information architecture, interaction design, prototyping, visual design — with Figma as your daily driver
• Demonstrated experience designing for complex, data-heavy, or expert-user products rather than consumer apps
• Track record of building or substantially owning a design system
• Experience planning and running usability testing, and acting on what it tells you
• Ability to collaborate effectively with domain experts, and to turn ambiguous problems into clear designs
• Strong adaptability and a quick learning mindset
• Good proficiency in English (written and spoken)

Nice to Have

• Real-time data in the browser (WebSockets, streaming telemetry)
• Experience with scientific, industrial, or laboratory control software
• Accessibility standards (WCAG) applied in practice
• Experience mentoring designers or leading design in a cross-functional team
• Prior experience with quantum computing or other deep-tech domains.
