Job Summary

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.

Responsibilities

- 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 transparent 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

Requirements

- Requirement: 35 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
