HackRFUSRPRTL-SDR
Role Overview
We're looking for a Cybersecurity Engineer with hands-on RF expertise to secure and stress-test wireless and radio-frequency communication links — including drone/UAS command-and-control (C2) channels, SDR-based systems, and cellular protocol stacks.
You'll work across signal analysis, protocol-level security testing, and link hardening for platforms used in defence and critical-infrastructure contexts.

Full Job Posting
We're looking for a Cybersecurity Engineer with hands-on RF expertise to secure and stress-test wireless and radio-frequency communication links — including drone/UAS command-and-control (C2) channels, SDR-based systems, and cellular protocol stacks. You'll work across signal analysis, protocol-level security testing, and link hardening for platforms used in defence and critical-infrastructure contexts.
NOTE
This is an implementation-focused engineering role (not pure research) — you'll be expected to build test rigs, run real attacks against RF links in a lab environment, and deliver hardening recommendations that get shipped.
Requirements
- ● Perform security assessments of RF communication links, including drone/UAS C2 channels and GCS (ground control station) links
- ● Build and operate SDR-based test setups (HackRF, USRP, RTL-SDR) using GNU Radio for signal capture, analysis, and attack simulation
- ● Analyze and test cellular protocol stacks (GSM/LTE/5G) for vulnerabilities, including work with tools such as OsmocomBB / gr-gsm
- ● Evaluate and implement RF link hardening measures — frequency hopping schemes, jamming/spoofing detection, key exchange protocols
- ● Conduct signal processing and decoding work (e.g., Viterbi decoding) to support protocol-level analysis
