Senior UI/UX Engineer- Quantum Computing (f/m/d)

<p style="text-align:start;"><strong><span style="color:#121317">eleQtron</span></strong><span style="color:#121317"> 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.</span><strong><span style="color:#121317"><br></span></strong></p><p><strong><span style="color:#121317">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.
