Senior Software Developer (m/w/x)

• About AQT
• At AQT we build quantum computers. Founded in Innsbruck, Austria, in 2018, we aim to bring quantum technologies out of the laboratory environment and turn them into everyday products. Our goal is a quantum computer based on trapped ions that is installed in normal IT infrastructure and can be readily operated from anywhere. We provide quantum technology for research laboratories and supercomputing centers. To our industrial customers, we offer quantum solutions directly and through partnerships with leading quantum software firms. In the past four years, we have managed to build up an amazing team with extraordinary ambition and talent, a world-class team of quantum physicists, engineers, and computer scientists working together to shape the future of quantum computing. For our team in Innsbruck, we are now looking for a skilled and motivated individual to join us as a Senior Software Developer.

• Your Role
• As a Senior Software Developer you will be leading the development of the AQT software stack. Your main focus will be developing state-of-the-art software and creating new features for AQT's quantum computers, integrating established tools and software frameworks for optimal systems operation. You will tightly work with stakeholders from operations, research, and engineering to identify, implement, and enable them taking advantage of the new software features. You will have the opportunity to work on a variety of projects simultaneously. This may include contributing to the development of internal tools and infrastructure to support the company's overall goals, participating in research and planning work as well as software architecture design. As a Senior Software Developer, you will be at the forefront of the quantum computing industry, pushing the boundaries of what is possible with cutting-edge technologies. If your skills and interests align, you will have the opportunity to transfer complex concepts from quantum optics and physics into high-quality quantum computer software. Thus, if you are excited about the prospect of developing software that will help shape the future of quantum computing, then this is the perfect opportunity for you.

Your Responsibilities

Design, develop, test, and maintain control software for AQT quantum computing systems and devices

Implement software features spanning the stack from embedded control to user-facing APIs, including coding, debugging, documentation, and automated testing

Use real-time control frameworks (e.g. on an FPGA or SoC systems) to build tools for programming and executing quantum circuits on quantum hardware

Collaborate closely with hardware, system, and quantum engineers to ensure seamless integration of software and hardware components

Develop new feature concepts, prototypes, and integrate them into operational software environments

Perform code reviews and uphold best practices in software design and development

Support DevOps processes across the software development life cycle

Contribute to continuous improvement in both technical and team practices

Your Qualifications

3+ years of experience in software development, ideally including embedded or systems-level experience

MSc (or equivalent experience) in Computer Science, Computer Engineering, Physics, or a related technical field

Strong proficiency in Python and/or Rust and experience with modern libraries and tools

Familiarity with version control systems, CI/CD pipelines, and state-of-the-art development workflows

Experience or strong interest in embedded systems, real-time control (e.g. quantum control frameworks like ARTIQ), or digital signal processing is beneficial

Exposure to FPGAs, HDLs (e.g. Migen), or compiler technology (e.g., LLVM) is advantageous

Background in quantum physics and understanding of quantum computing concepts is a plus

Excellent analytical, debugging, and problem-solving skills

Comfortable working in a highly collaborative, fast-paced, and multidisciplinary team environment

Strong communication skills in both spoken and written English
