University Assistant (Post-Doc) for Astronomical Data Flow Systems

If you love to design and implement reliable software systems that support groundbreaking astronomical discoveries, work at the interface of hardware and software for world-leading observatories, and collaborate with international teams of scientists and engineers – then welcome to the team!

Our ground-based astronomical instrumentation software group at the University of Vienna combines technical excellence with scientific ambition. We value respectful communication, professionalism, and the shared aspiration to contribute to humanity’s exploration of the universe.

Your working place:

The Department of Astrophysics with currently around 90 members is part of the Faculty of Earth Sciences, Geography and Astronomy at the University of Vienna.

You will work at the interface of astronomical research and software engineering and will play a central role in shaping the software that enables the success of the ELT’s first-light instruments, MICADO and METIS. Our group develops and maintains custom-written software that will simulate, process, validate, and store data from some of the most advanced astronomical instruments ever to be built. Colleagues from many countries and backgrounds will rely on your expertise in robust, industry-standard software practices and your ability to bridge the worlds of astronomy, engineering, and IT.

The position is nominally set for 24 months, preferably by 15 March 2026. 

Your future tasks:

Active participation in research, teaching & administration, which means:

• You implement software products based on existing design documents for ELT instruments.
• You define, install, and maintain the network infrastructure needed to connect software and hardware during instrument Assembly, Integration, and Testing (AIT).
• You collaborate with the astronomers and instrument-builders in the MICADO and METIS consortia teams to test, verify, update, and document software and operational use cases.
• You solve technical IT challenges during integration in the AIT construction hall and later at the telescope site.
• You work closely with local scientists to guarantee that the developed software meets or exceeds ESO’s scientific and performance requirements.
• You hold courses independently within the scope of the provisions of the collective bargaining agreement.

Your Profile

Must-haves

• A minimum of 3 years of professional experience in software development for astronomy-related projects, preferably in data flow systems or data reduction pipelines.
• Experience with the ESO DFS software stack, such as EDPS, EsoRex, CPL, etc.
• A PhD / Doctoral Degree in astronomy, physics, or equivalent professional expertise.
• Solid knowledge of software engineering methods, network/system administration, and version control systems.

Good-to-haves

• Hands-on experience with testing, verification, and documentation of the complex software systems involved with telescope instrumentation projects.
• Fluency in English (spoken and written); knowledge of German is an asset.
• Strong opinions on good software practices.

Your working style is independent, structured, and solution-oriented. You thrive in collaborative, international teams and enjoy tackling technical challenges in dynamic environments. You are a team player and have good social and communicative skills.
