This position is contingent upon contract award.

Leidos is seeking an RF Engineer III to design, analyze, and test RF communication links for the Army’s Counter‑UAS (C‑UAS) Network Communication System (NCS). You’ll ensure secure, reliable RF connectivity supporting M‑LIDS and FS‑LIDS systems used in Short‑Range Air Defense (SHORAD) missions.

This role spans RF link design, propagation modeling, EW threat mitigation, RF hardware integration, and field testing—working closely with systems, software, and cybersecurity teams in an Agile environment.

Key Duties

• Perform RF link budget analysis, propagation modeling, and spectrum assessments.


• Design RF links/waveforms supporting secure, reliable tactical data transmission.


• Integrate RF hardware (radios, antennas, transceivers) with secure network architecture.


• Mitigate interference, jamming, and EW threats; design anti‑jam/frequency‑agile approaches.


• Optimize RF link latency, throughput, and reliability for remote monitoring/control.


• Support RF testing, EMI/spectrum compliance, and field/range evaluations.


• Provide RF input to RMF/ATO security requirements and assessments.


• Present RF analysis and recommendations at TIMs; maintain RF sections of system documentation.

Basic Qualifications

• Bachelors in EE/RF/Communications Engineering + 8+ years RF engineering experience.


• Current Secret clearance with the ability to obtain a Top Secret clearance.


• Experience with RF link analysis, propagation modeling, and spectrum planning.


• Hands‑on RF hardware/system design and integration.


• Familiarity with EW threats and anti‑jam RF design.


• Experience with RF test tools (spectrum/network analyzers, signal generators).


• Knowledge of DoD cybersecurity and spectrum management requirements.


• Strong RF technical writing and ability to brief government stakeholders.

Preferred Qualifications

• Experience with C‑UAS/SHORAD/LIDS systems.


• RF integration for fielded tactical systems (M‑LIDS/FS‑LIDS).


• Experience with MATLAB/SystemVue or similar RF modeling tools.


• SDR/waveform development experience.


• Military/federal spectrum coordination experience.


• Agile/Scrum engineering experience.
