The Opportunity

  • Innovative and collaborative workplace with fantastic flexibility 
  • Work in a world-class research & development precinct
  • Join CSIRO and support Australia's premier scientific organisation! 

The Technologies for Radio Astronomy program at CSIRO Space and Astronomy (S&A) supports Australia’s leadership in radio astronomy technology and infrastructure. We operate several world-class radio astronomy observatories collectively known as the Australia Telescope National Facility or ATNF. We design and deliver instrumentation and data-processing systems for our own telescopes, for international facilities, and even for space flight.

Your duties will include:

In your role as the Phased Array Systems Engineer you will provide phased-array beamforming and system expertise to the CSIRO Space & Astronomy team as well as external teams, developing innovative instrumentation for radio telescopes and satellite ground stations. 

You will develop procedures to calibrate the antenna array and dynamically update digital beamformer weights to track satellites in low-earth orbit. Electromagnetic (EM) models of the antenna array will be provided by other team members.  The Phased Array Systems Engineer will build  software around the EM models to predict beam weights and beam performance as a function of azimuth, elevation, polarisation, and frequency.

  • Working closely with antenna and signal processing engineers to optimise digital beamforming and calibration approaches for the array.
  • Writing software to evaluate predictions of the beamformed array performance in various scenarios and to calculate weights for the digital beamformer to steer beams.
  • Exploring and implementing spatial nulling techniques in the digital beamformer to reject unwanted radio frequency interference (RFI).
  • Working closely with hardware and software engineers to validate the digital beamformer and implement dynamic beam tracking to receive signals from satellites and null unwanted signals.
  • Conducting on-site commissioning measurement / verification of beamforming performance.
  • Contributing to innovation in beamforming and calibration across a variety of radio astronomy, space tracking, and communication projects.

Location: Marsfield (Sydney) New South Wales
Salary: AU$117k - AU$138k per annum (pro-rata for part-time), plus up to 15.4% superannuation
Tenure: Specified term of 3 years
Reference: 80203

To be considered you will need:


  • A minimum of a bachelor’s degree in an area relevant to this position. 
  • Familiarity with digital signal processing (DSP) theory and techniques, such as FFT’s, correlation, linear filters, linear algebra, and demonstrated ability in numerical simulation of DSP systems.
  • Demonstrated experience and proficiency in programming, data manipulation, and visualisation using languages such as Python and C/C++.
  • Aptitude for system development, testing, integration, and verification in a collaborative environment under version control.
  • Ability to work effectively both individually and as a member of a collaborative technical team.


  • Experience in antenna array signal processing, preferably system modelling and/or measurement for beamforming and array calibration.
  • Ground station and satellite tracking domain knowledge including digital communications, modulation, coding, and link budgets and experience with associated hardware and software.  
  • Ability to  help model and measure the signal-to-noise ratio and bit error rate for the end-to-end signal path.
  • Practical experience with digital signal processing systems implemented on field programmable gate array (FPGA) platforms, including basic knowledge of hardware description language (HDL). 
  • Experience with radio astronomy systems including low-noise receiving arrays and associated digital signal processing systems and techniques.

CSIRO thrives on innovation; innovation that is harnessed by the diversity of the minds and lived experiences brought to our greatest challenges. If you meet some, but not all requirements, we encourage you to submit your application.
