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
Requirement:
● 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
Good to Have:
● 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

- 3-5 years of experience in cybersecurity, RF/wireless security, or signal processing engineering
