Cybersecurity Engineer RF

Job Description

​

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

●     Perform red-team / adversarial testing
against wireless and RF systems, and document findings with clear remediation
guidance

●     Write scripts and tooling in Python
(with DSP libraries such as NumPy/SciPy) to automate testing and analysis
workflows

●     Collaborate with drone platform and
embedded teams (DJI, ArduPilot, PX4) on OTA update security and platform
hardening

●     Produce technical documentation
suitable for defence customers and internal engineering review

●     3–5 years of experience in
cybersecurity, 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/5G
protocol stacks and associated security weaknesses

●     Practical RF signal analysis skills —
capture, decode, and interpret radio signals

●     Proficiency in Python for scripting
and analysis; familiarity with DSP libraries (NumPy, SciPy) a strong plus

●     Understanding of frequency hopping
schemes and jamming/spoofing detection techniques

●     Experience with, or strong conceptual
grounding in, red team / adversarial security testing methodology

●     Exposure to drone/UAS platforms (DJI,
ArduPilot, PX4) or ground control software (QGroundControl, Mission Planner)

●     Familiarity with key exchange
protocols and C2 link security/hardening

●     Background in SIGINT/COMINT concepts

●     Exposure to defence procurement or
DRDO/MoD project environments

●     C/C++ in addition to Python

Benefits

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

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