Job Description

Join Our Mission to Advance Cybersecurity with Quantum Communication

At Quantum Technology Laboratories GmbH (qtlabs), we are at the forefront of innovation in optical and quantum-based communication technologies. Our team develops cutting-edge quantum key distribution (QKD) security-proofs and simulations toolkits for space and terrestrial QKD applications. Based in Vienna, our center of excellence drives technological advancements that secures communication around the world.

 

Shape the Future of Quantum Simulation Software

In this role, you will take on a key position in the development of our next-generation simulation software. Your main responsibilities will include designing the architecture of the simulation framework, selecting an appropriate programming language, and driving the implementation process. Your work will have a significant impact on the technological foundation and future viability of the software suite. You will collaborate with a dynamic and motivated team of physicists and computer scientists, working at the intersection of software development and complex numerical simulations.

Your Responsibilities:

  • Evaluate and select a suitable programming language for the numerical simulation framework (C/C++, Python, Julia, or Rust).
  • Design and implement the software architecture for the simulation framework.
  • Develop and integrate new features to optimize simulations and numerical methods.
  • Lead the implementation process and closely collaborate with relevant teams.
  • Ensure a scalable and high-performance backend structure to support future extensions.
  • Optimize performance and scalability of simulation tools.
  • Collaborate with scientific partners and incorporate the latest research findings into the software
 

Required Profile

  • A minimum of 2 years of professional experience in software development, with proven expertise in planning and designing software architectures.
  • Excellent programming skills in one of the following languages: C/C++, Python, Julia, or Rust.
  • Proficiency in reading Matlab code (optional but advantageous).
  • Strong knowledge of software architecture/design, system integration, scalability, and performance optimization.
  • Experience with convex optimization and numerical simulation methods is a strong plus.
  • Leadership and project management experience in software development and architecture is an advantage.
  • Independent, structured work style with a clear focus on achieving goals.
  • Team-oriented mindset and readiness to work in a hybrid model (remote and onsite).
 

What we Offer

  • The chance to lead the development of cutting-edge quantum simulation tools with real-world applications.
  • A collaborative environment working alongside experts in quantum physics, mathematics and computer science.
  • Flexible work arrangements in a hybrid model combining remote and onsite collaboration.
  • The opportunity to make a lasting impact on the future of quantum technologies.

The minimum gross salary for this position is € 3,284.86 per month (full-time basis) in accordance with the collective agreement. However, there is a willingness to overpay in line with the market, depending on experience and qualifications.

We look forward to receiving your application!
