Laboratory Technician / Hardware Technician (f/m/d)

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 Laboratory Technician / Hardware Technician (f/m/d)

Responsibilities:
As a Laboratory Engineer / Technician (f/m/d), you will work hands-on to assemble, integrate, test, and maintain complex quantum computing hardware systems. You will ensure that systems operate reliably from initial assembly through commissioning and handover to hardware operations. This is a purely hands-on role with no design responsibility or theory-heavy research work. You ensure that the hardware operates reliably, cleanly, and safely while working closely with engineers and scientists to support them in complex technical tasks.

• Assemble, integrate and modify mechanical, electrical and opto-mechanical laboratory systems

• Build and maintain complex subsystems, including:

  • Vacuum chambers and vacuum components

  • Precision mechanical assemblies

  • Cabling, wiring and connector systems

  • Electronics racks, enclosures and lab infrastructure

  • Optical mounts and basic optical alignments

• Perform hands-on technical work such as:

  • Drilling, tapping, mounting and fastening of precision parts

  • Cable routing, labeling and documentation

  • Leak checks and basic vacuum work

  • Visual inspections, functional checks and fault isolation

• Support system integration, testing, and commissioning

• Troubleshoot and fix practical hardware issues:

  • Loose connections, misalignments, mechanical tolerances

  • Wiring errors, damaged components, assembly mistakes

• Perform preventive maintenance and basic repairs

• Maintain a clean, safe and well-organized lab environment

• Document work in a clear, technical and reproducible manner
