Role Summary:

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

Key Responsibiliies:

● 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

What We Offer:

● A small, high-context engineering teamwhere individual contributions are highly visible

● Opportunity to work across the fullstack — RF, embedded, and protocol-level security
