The opportunity

The SKA Observatory (SKAO) is a next-generation radio astronomy facility that will revolutionise our understanding of the Universe and the laws of fundamental physics. Enabled by cutting-edge technology, it promises to have a major impact on society, in science and beyond.


In Australia, the SKAO is collaborating with CSIRO to operate and support the construction of the low frequency telescope (SKA-Low) in remote Western Australia on Wajarri Yamaji Country.


The Traditional Owners and native title holders, the Wajarri Yamaji, have gifted CSIRO with the traditional name Inyarrimanha Ilgari Bundara for the CSIRO Murchison Radio-astronomy Observatory, home to the SKA-Low telescope. The traditional name means ‘sharing sky and stars’ in the Wajarri language.


The Radio Frequency Interference (RFI) Technician will form part of the existing SKA-Low RFI & EMC team. This position will be based at the Engineering Operations Centre (EOC) in Geraldton, Western Australia. A significant amount of work will be required at the SKA-Low telescope site at Inyarrimanha Ilgari Bundara, the CSIRO Murchison Radio-astronomy Observatory. The position will also form part of the wider SKA RFI and EMC group that consists of engineers and technicians responsible for ensuring the RFI and EMC integrity of the observatory is maintained. Actively engaging in technical analysis and problem solving of pertinent interference topics will be a rewarding and important part of this role. 


Your duties will include:

  • Utilize spectrum analyzers, signal generators, and other specialized equipment to perform RFI characterisation and qualification testing.

  • Assist with testing and analysing RFI and interference related issues.

  • Collaborate with engineering teams to design and implement effective solutions for RFI problems.

  • Maintain detailed records of RFI incidents, including observations, test results, and corrective actions taken.

  • Communicate effectively with internal stakeholders, including engineers, technicians, and management, to coordinate RFI mitigation efforts.


Location:     Geraldton, Western Australia

Salary:         AU$93,267 - AU$105,517 plus 15.4% superannuation

Tenure:        Indefinite – Full-Time, Part-Time or Job-Share

Reference:  96699

To be considered you will need:


  • Formal qualification in electrotechnology or equivalent relevant experience in RF systems, telecommunications, or a related field.

  • Proven knowledge and understanding in radio frequency interference or electromagnetic compatibility testing, analysis, and mitigation techniques, or in radio frequency signal detection and analysis, including antenna performance characterisation.

  • Proficiency in using spectrum analysers, signal generators, and other RF test equipment.

  • Strong understanding of RF principles and test methodologies

  • Effective communication and interpersonal abilities, with the capacity to work collaboratively in a team environment.

  • Familiarity with data analysis software or computational analysis tools (e.g., MATLAB, CST Microwave Studio, Python).



  • Certification in radio frequency engineering or related field (e.g., Certified Wireless Network Professional - CWNP).

  • Experience with software-defined radio (SDR) platforms and digital signal processing (DSP) techniques.

  • Knowledge of antenna design and RF propagation principles.

  • Understanding of electromagnetic compatibility (EMC) considerations in RF system design and installation.
