Your space-enabled career begins here

Candidate Experience and Skills Summary

• Demonstrated experience in RF circuit design and prototyping, including the design of Low Noise Amplifier (LNA) circuits and Power Amplifier (PA) circuits.

• Strong experience with an EM hardware simulation tool such as Ansys HFSS or CST for optimisation.

• Experience using Altium or Microwave Office for schematic capture and layout.

• Clear understanding of RF design principles and an ability to apply these for critical component selection.

• Detailed understanding of how to optimise a system and LNA design for best noise performance.

• Experience with lab testing of prototypes using equipment such as Spectrum Analysers and Vector Network Analysers.

• Clear communication skills and an ability to write clear test plans and test reports.

• Track record of documenting while designing and familiarity with tools such as Confluence and Sharepoint for updating design information.

• Experience with designing and coordinating the manufacturing and packaging of MMIC devices is desirable.

• Experience in designing commercial products with an aim to minimise cost and power consumption while still maintaining performance.

Purpose and Responsibilities of the Role

As a Senior RF Engineer you will be part of a talented team of engineers designing and building Quasar’s Phased Array Ground Stations.

Quasar’s Phased Array Ground Stations are optimised for sub-zero operating conditions and are characterised by careful and efficient hardware system design, enabling cost effective and novel solutions to a growing infrastructure challenge posed by the expanding Low Earth Orbit (LEO) satellite market. The Senior RF Engineer will be an integral member of the hardware design team with an aim to solve this challenge.

This will require you to:

• Design, simulate and optimise RF power amplifier circuits for low-cost implementation, based on array performance specifications.

• Design, simulate and optimise RF LNA circuits for low-cost implementation.

• Lead the design/integration of LNA MMIC devices.

• Design, simulate and optimise distributed element filters and matching circuits.

• PCB layout of critical RF circuits.

• Work with hardware engineers and antenna engineers to establish both unit and system prototype test and verification plans.

• Testing and characterisation of prototypes using laboratory equipment.

• Participate in design reviews.

• Apply knowledge of noise, matching, linearity, and other device characteristics to design work.

We offer you:

• An exciting technical project with scope to collaborate with research groups and work on emerging technology.

• An opportunity to join a young team and shape/influence hardware design direction.

• Opportunity to grow and develop new skills as part of a truly multi-disciplinary hardware team.

• An opportunity to become an early integral member in the Australian space industry.

• Technical and industry training where it is needed.

• A team where people are prioritised and work satisfaction and happiness is of utmost importance.

Company Background
