Cybersecurity Engineer RF

Globals Ites; Bengaluru; On-site; INR 2,000,000 - 4,200,000; Full time

Job summary

Globals Ites is seeking a Cybersecurity Engineer with hands-on RF expertise to secure RF links including drone C2, SDR-based systems, and cellular stacks. You will build test rigs, run real attacks in a lab, and deliver hardening recommendations that ship.

The role combines signal analysis, protocol testing, and practical hardening for defence and critical infrastructure contexts in an implementation-focused engineering environment.

Qualifications

• 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.

Responsibilities

• Perform security assessments of RF communication links, including drone/UAS C2 channels and GCS 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 on OTA update security and platform hardening.
• Produce technical documentation suitable for defence customers and internal engineering review.

Job description

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
