Today, Globals enjoys a strong position in the industry as a high-performing leader through its technology innovation and remarkable domain expertise. Globals is a CMMI Level 5 certified company. Role Summary: 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
Key Responsibiliies: ● 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
What We Offer:
● 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
