Software Engineer for Quantum Communication Systems: application development


QuTech is a mission-driven research institute, run by Delft University of Technology (TU Delft) and the Netherlands Organisation for Applied Scientific Research (TNO). Together, we work on a radically new technology with world-changing potential, developing scalable prototypes of a quantum computer and an intrinsically safe quantum internet.

QuTech is creating the quantum future. We believe that quantum technology can be a game changer in many social and economic sectors, including health, agriculture, climate and safety. To achieve our ambitious goals, we bring together scientists, engineers and industry in an inspiring environment – with plenty of space for ambition, entrepreneurship and innovation. QuTech’s research and engineering activities are conducted in three divisions: Quantum Computing, Quantum Internet and Qubit Research. Our divisions and support teams include 220 FTE and over 300 dedicated people, and we are happy to welcome new colleagues who share our vision and enthusiasm!

Job Description

Our software engineer is responsible, both independently and within a small team, for extending existing sub-systems and building new sub-systems, for key software aspects of a secure quantum telecommunications system, in which security is partially based on quantum physics. The ideal candidate is able to work independently without a narrow focus and is comfortable tackling different types of problems. This involves defining communication protocols between quantum communications equipment, securing that communication with conventional cryptography, interfacing the quantum systems with existing communication/routing infrastructure, analyzing known cryptography protocols, API design, and working with prototype systems. Tasks will be very broad, and the software engineer is independent, flexible and comfortable determining system requirements. Moreover, our software engineer has product development experience and can work alongside academics.


Note: We do not expect that applicants will meet all the requirements mentioned below.

  • Experience with software architecture design and programming, preferably systems with high security requirements (3 years+)
  • Experience with network protocol design and programming (3 years+)
  • Experience analyzing cryptographic algorithms (1 years+)
  • Experience with secure communications (3 years+)
  • Master’s Degree in computer science, engineering or comparable discipline
  • Comfortable reading scientific papers, and implementing new published algorithms
  • Experience in C++ and Python (3 years+)
  • Experience with agile working methods
  • Demonstrated skills in the entire development cycle, ideally at a commercial vendor of communications / security equipment: architecture, design, implementation, review, unit and functional testing, simulation, version control, requirements and defect tracking, and hardware integration (3 years+)
  • Passionate about advancing communication technologies to entirely new heights
  • Familiarity with quantum communications, quantum mechanics, or math is a plus but not required
  • Proactive and able to independently devise solutions
  • Team player, in a mixed team of software and hardware engineers, and scientists
  • For this vacancy an EU work permit is needed

Conditions of employment

This offer contains a temporary appointment for 1 year with the prospect of a permanent contract. The full-time salary is based on VSNU-CAO Scale 10-11 (salary 2,790 – 5,127 euros monthly on full-time basis). The actual salary will be based on your knowledge and relevant work-experience. Full-time means 38 working hours per week.TU Delft/QuTech offers a customizable compensation package, an attractive pension scheme, holiday allowance, a generous amount of holidays, a 13th month pay, a discount for health insurance and sport memberships, and a monthly work costs contribution. Flexible work schedules can be arranged. An International Children’s Centre offers our employees child care and an international primary school. Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities (VSNU-CAO). Dutch citizenship or a European working permit is required to apply.

TU Delft

Your contract will be with TU Delft. Delft University of Technology is built on strong foundations. As creators of the world-famous Dutch waterworks and pioneers in biotech, TU Delft is a top international university combining science, engineering and design. It delivers world class results in education, research and innovation. For generations, our engineers have proven to be entrepreneurial problem-solvers both in business and in a social context. TU Delft offers 16 Bachelor’s and 32 Master’s programs to more than 23,000 students. Our scientific staff consists of 3,500 staff members and 2,800 PhD candidates. Together we imagine, invent and create solutions using technology to have a positive impact on a global scale. Challenge. Change. Impact!

Quantum Internet Division

The Quantum Internet division seeks to develop technologies that enable quantum communication between any two places on earth. Several major new and potentially game-changing applications have already been identified for this radically new capability. One such application is a fundamentally secure means of communication, where privacy is guaranteed by the laws of physics. Quantum processors can also be connected into a quantum network, in order to assemble a large quantum computing cluster. Combining a quantum internet and a networked quantum computer allows remote users/providers to perform secure quantum computing ‘in the cloud’. The Quantum Internet Division maintains an integrated effort, spanning both quantum hardware and software at the cutting edge of research and development. Our team of 90 people works in close collaboration with QuTech’s Quantum Computing and Qubit Research divisions.

The Quantum Internet Division is working on realizing a small-scale test network linking both simple quantum equipment capable of enabling cryptographic applications such as secure communication, as well as sophisticated quantum processing devices across several Dutch cities in 2021. It has the technological know-how enabling early stage networks in metropolitan areas such as the Randstad, and the ambition to bring this technology to a practical reality. The Division has an integrated effort at the cutting edge of research and development, spanning quantum hardware and software. It is recognized as a world leader in quantum networking, and leads the European Quantum Internet Alliance (QIA), a team effort of academia and industry across Europe with the long-term goals of realizing a large-scale quantum internet. The Division is a highly collaborative multi-disciplinary effort involving researchers and engineers from across the world. QINC is a young, ambitious, fast moving team determined to be the first to achieve a technological goal akin to the first moon landing. We are now seeking several software engineers to join us in this exciting endeavor. The software engineer is part of the QuTech Quantum Internet Division, focusing on Quantum Communication.
