Job Description

Join Our Mission to Advance Cybersecurity with Quantum Communication

At Quantum Technology Laboratories GmbH (qtlabs), we develop quantum key distribution systems and optoelectronic solutions for space and terrestrial applications. Based in Vienna, our engineers and scientists work on technologies for secure global communication.

Develop, integrate, and maintain advanced optical and mechatronic systems for cutting-edge space and terrestrial communication technologies.

About the Position

We are looking for a motivated Technician to join our engineering team in the development, integration, testing, and maintenance of optical and mechatronic systems.

In this role, you will help develop and improve measurement setups for optical components, integrate laser optics for free-space optical communication, and contribute to the automation of optical alignment and measurement processes.

You will work closely with colleagues from different engineering disciplines, combining electronics, mechanics, optics, and software development. The position offers a good opportunity to apply your technical knowledge, gain practical experience, and further develop your engineering skills.

We particularly welcome candidates with completed technical education (HTL or equivalent) or a technical apprenticeship in Electrical Engineering, Electronics, Mechatronics, Automation Technology, or a related field who are interested in working on complex technical systems.

Main Responsibilities

Your work will involve a combination of laboratory development, practical assembly, testing, and system integration. Depending on the project, your responsibilities will include:

• Assembly, alignment, and characterization of optical and optomechanical systems.
• Development and improvement of optical measurement setups and automated alignment procedures.
• Integration, testing, and troubleshooting of electronic and mechanical components and control systems.
• Maintenance, testing, and commissioning of telescope systems.
• Support of laboratory experiments, system integration, and field measurement campaigns.

You will also help document measurement procedures, test results, and technical modifications.

Required Qualifications

We are looking for candidates with a solid technical foundation in Electrical Engineering, Electronics, Mechatronics, Automation Technology, or a related field, gained through technical education (HTL or equivalent), a completed technical apprenticeship, or a comparable qualification.

• Electronics and Measurement Technology: Basic knowledge of electronic circuits, sensors, actuators, and measurement equipment for testing and characterizing technical systems.
• Mechanical Design and Assembly: Basic knowledge of CAD software, mechanical design, and precision assembly of mechanical and optomechanical components.
• Programming: Basic knowledge of Python and/or C++ for measurement automation, data acquisition, and hardware control.
• Technical Development: Basic knowledge of structured engineering workflows, system integration, testing, troubleshooting, and technical documentation.

You enjoy working hands-on with technical equipment, approach problems in a structured and solution-oriented way, and are comfortable working both independently and as part of a team. Most importantly, you are curious about technology and motivated to expand your knowledge.

Preferred Qualifications

Knowledge, practical experience, or an interest in one or more of the following areas would be an advantage:

• Optics, photonics, laser technologies, and optical measurement techniques.
• Astronomy and telescope technology.
• Embedded systems, electronics, and hardware interfaces.
• Robotics, automation, and control systems.

Previous professional experience in optics or laser systems is not required. We welcome applicants who have gained relevant experience through school projects, internships, personal projects, or previous technical positions.

What We Offer

At qtlabs, you will work on optical and quantum communication technologies, including satellite communication systems and optical ground stations. Our projects cover a broad range of engineering activities, from laboratory development to the integration and operation of complex technical systems.3

You can expect:

• Involvement in national and international projects, including activities in cooperation with the European Space Agency (ESA).
• Practical work with specialized optics and laser laboratories, measurement equipment, and telescope systems.
• Collaboration with experienced engineers and researchers who support you in developing your technical skills.
• Opportunities to gain experience in optics, electronics, automation, and quantum communication technologies.
• Flexible working hours and a modern workplace in Vienna.

The position offers varied technical tasks, the opportunity to take on responsibility as your experience grows, and a combination of laboratory work, engineering development, and occasional field measurement campaigns.

The minimum gross salary for this position is €3.157,47 per month on a full-time basis, in accordance with the applicable collective agreement. The actual compensation will be above this minimum and will reflect the candidate’s experience and qualifications.
