Siegen, Germany
Posted on Jan 27, 2026

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 Engineer/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.

  • Assemble, integrate, and maintain quantum computing hardware from wire-bonded chip level to fully enclosed, self-contained systems

  • Integrate and validate all subsystems, including vacuum, electronics, optomechanics, cryogenics, lasers, microwaves, and control systems

  • Perform subsystem and system-level verification, including wiring checks, signal integrity testing, optical alignment, and vacuum leak detection

  • Execute functional, integration, and acceptance tests before system handover

  • Support commissioning activities and ensure systems meet defined performance and reliability requirements

  • Diagnose and resolve unexpected system behavior in close collaboration with design and operations teams

  • Conduct preventive maintenance and timely service interventions to ensure stable operation

  • Maintain clear and structured documentation of assembly, testing, and service activities

Required skills:

  • Bachelor’s degree in Physics, Applied Physics, Electrical Engineering, Mechanical Engineering, or a related field

  • 5+ years of hands-on experience building, maintaining, testing, or servicing complex laboratories or industrial hardware systems

  • Hands-on troubleshooting skills across hardware, electronics, optics, and vacuum subsystems

  • Structured approach to testing, documentation, and operational handover

  • Proven experience with systems of comparable complexity, such as:

    o Electron microscopes (SEM, TEM, FIB)

    o Mass spectrometers (ToF, QMS, SIMS, ICP-MS)

    o Semiconductor process equipment (e-beam lithography, ALD, MBE, CD-SEM, plasma etch tools)

    o Small particle accelerators or ion implantation systems

Nice-to-have:

  • Experience with in-house commissioning or field service of complex laboratory or industrial equipment

  • Exposure to quantum hardware or advanced experimental physics environments

  • Experience working in cleanroom or controlled laboratory settings

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 game.

  • 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.

  • 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.
