Senior RF / DSP Engineer
Wireless Signal Analysis and Protocol Decoding
Location: Adelaide, South Australia
$Generous salary on offer
Join a specialist engineering team working on advanced wireless analysis technology operating in complex real world environments. This role sits at the intersection of RF engineering, communications theory and software development, focused on extracting meaning from real over the air signals rather than simulated lab data.
You will analyse unknown wireless transmissions, reconstruct protocols and build robust decoding pipelines used to understand how modern wireless systems behave in practice.
The Role
You will investigate real world RF captures and determine how systems operate at the physical layer. This includes identifying modulation types, reconstructing packet structures and developing decoding algorithms for modern wireless technologies.
Responsibilities
Signal Analysis and Reverse Engineering
Analyse captured RF signals to identify modulation schemes such as OFDM, QPSK, QAM and FSK
Decode MIMO physical layer waveforms across LTE, 5G NR, Wi Fi and related technologies
Interpret FHSS, TDMA, OFDMA and SC FDMA frame structures including pilots, control channels and data channels
Read and interpret technical standards and specifications including 3GPP and IEEE documentation
Investigate protocol behaviour and anomalies from real world recordings
Algorithm Development
Develop synchronisation, detection, demodulation and decoding algorithms
Build PHY layer reconstruction and validation pipelines using real over the air data
Implement performance optimisation across memory and compute constrained workflows
Develop automated processing and simulation pipelines including CI CD
Testing and Validation
Perform unit testing, system testing and performance benchmarking
Validate decoding reliability in noisy and multipath environments
Work closely with research teams to validate assumptions and findings
Document methodology and engineering conclusions clearly
About You
You are comfortable working from incomplete information and enjoy figuring out how systems actually work rather than how they are supposed to work. You likely come from RF communications, DSP, telecommunications or signal analysis environments.
Required Experience
Degree in Electrical Engineering, Telecommunications or similar
Around 5+ years working with RF communications and DSP
Strong DSP fundamentals including filtering, correlation, frequency analysis and estimation
Experience analysing digitally modulated signals such as OFDM, QPSK, QAM and FSK
Understanding of multi antenna systems including spatial diversity and multiplexing
Knowledge of wireless multiple access schemes and frame structures
Experience with MATLAB or Python scientific stack
Understanding of RF signal chains and performance metrics such as SNR, BER and EVM
Experience using RF test equipment such as spectrum analysers and signal generators
Ability to analyse signals in noisy real world conditions
Desirable Experience
Software defined radio platforms
Embedded or real time signal processing
Wireless security concepts
Experience working with complex RF environments
Machine learning applied to signal analysis
Relevant hobbyist or independent research experience is also valued where depth of understanding is demonstrated.
Why This Role
Work on real signals rather than theoretical models
Deep technical engineering challenges
Highly specialised team environment
Long term technical ownership and impact
Adelaide based role with a strong research and engineering culture
