Job Description
We're looking for a Cybersecurity Engineer with hands-onRF expertise to secure and stress-test wireless and radio-frequencycommunication links — including drone/UAS command-and-control (C2) channels,SDR-based systems, and cellular protocol stacks. You'll work across signalanalysis, protocol-level security testing, and link hardening for platformsused in defence and critical-infrastructure contexts.
NOTE
This is an implementation-focused engineeringrole (not pure research) — you'll be expected to build test rigs, run realattacks against RF links in a lab environment, and deliver hardeningrecommendations that get shipped.
Requirements
● Perform security assessments of RFcommunication links, including drone/UAS C2 channels and GCS (ground controlstation) links
● Build and operate SDR-based testsetups (HackRF, USRP, RTL-SDR) using GNU Radio for signal capture, analysis,and attack simulation
● Analyze and test cellular protocolstacks (GSM/LTE/5G) for vulnerabilities, including work with tools such asOsmocomBB / gr-gsm
● Evaluate and implement RF linkhardening measures — frequency hopping schemes, jamming/spoofing detection, keyexchange protocols
● Conduct signal processing and decodingwork (e.g., Viterbi decoding) to support protocol-level analysis
● Perform red-team / adversarial testingagainst wireless and RF systems, and document findings with clear remediationguidance
● Write scripts and tooling in Python(with DSP libraries such as NumPy/SciPy) to automate testing and analysisworkflows
● Collaborate with drone platform andembedded teams (DJI, ArduPilot, PX4) on OTA update security and platformhardening
● Produce technical documentationsuitable for defence customers and internal engineering review
Requirement:
● 3–5 years of experience incybersecurity, RF/wireless security, or signal processing engineering
● Hands-on experience with SDR hardware(HackRF, USRP, or RTL-SDR) and GNU Radio
● Working knowledge of GSM/LTE/5Gprotocol stacks and associated security weaknesses
● Practical RF signal analysis skills —capture, decode, and interpret radio signals
● Proficiency in Python for scriptingand analysis; familiarity with DSP libraries (NumPy, SciPy) a strong plus
● Understanding of frequency hoppingschemes and jamming/spoofing detection techniques
● Experience with, or strong conceptualgrounding in, red team / adversarial security testing methodology
Good to Have:
● Exposure to drone/UAS platforms (DJI,ArduPilot, PX4) or ground control software (QGroundControl, Mission Planner)
● Familiarity with key exchangeprotocols and C2 link security/hardening
● Background in SIGINT/COMINT concepts
● Exposure to defence procurement orDRDO/MoD project environments
● C/C++ in addition to Python
Benefits
● A small, high-context engineering teamwhere individual contributions are highly visible
● Opportunity to work across the fullstack — RF, embedded, and protocol-level security
