Job summary

eleQtron is seeking a Senior UI/UX Engineer to own the end-to-end experience for our quantum computing interfaces, in Hamburg or Siegen. You will lead the customer-facing web platform for quantum programs and the internal operator interface, setting the design direction and building a shared component library.

The role is design-led, requiring hands-on implementation, prototyping, and a strong emphasis on accessibility and usability across surfaces and APIs.

Qualifications

• Minimum 5+ years of professional experience in product or interaction design with a shipped portfolio.
• Ability to build reusable production-ready components in TypeScript and React.
• Mastery of full design toolkit (research, IA, interaction, prototyping, visual design) with Figma daily use.
• Experience designing for complex, data-heavy or expert-user products rather than consumer apps.
• Track record of building or owning a design system.
• Experience planning and running usability testing and acting on findings.
• Ability to collaborate with domain experts and translate ambiguity into clear designs.
• Strong adaptability and quick learning mindset; excellent written and spoken English.

Responsibilities

• Own design direction for customer-facing cloud platform and internal operator interface as one product family.
• Conduct user research with operators and physicists to transform insights into design decisions.
• Produce wireframes, interactive prototypes, and high-fidelity designs for both surfaces.
• Build and own a production-ready design system and components used by engineers.
• Make dense telemetry and calibration data legible with clear visualisation patterns.
• Validate shipped interfaces with usability testing to ensure design intent meets product.
• Shape APIs with backend and platform engineers, advocating for user perspective early.
• Set accessibility, usability, and visual consistency standards across the team.

Job description

eleQtron develops and operates full-stack quantum computers based on trapped-ion technology. Quantum computing is a new computing paradigm rapidly approaching commercial viability. Our unique approach combines laser-cooled trapped ions with microwave control and tailored magnetic fields. Our next-generation computing machines under development will be able to find solutions to problems that are out of reach today, thus enabling new innovative products and services for a brighter future.

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.

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

Required Skills:

• 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 (Bonus)

• 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.

What you can expect from eleQtron:

• Competitive salary: We value our team members and therefore provide remunerations that reflect this, additionally rewarding achievements

• 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

• Wellness Package: We offer health-promoting benefits such as fitness programs like UrbanSportsClub to support your well-being

• Bike Leasing: Stay Mobile and Sustainable with Our Company Bike Leasing Program

• Moving Benefits: A warm welcome! We are happy to support employees who move for us with a bonus

• 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
