Overview
Thorheed Titan is seeking a hands-on RF / 5G Systems Engineer with demonstrated experience building and running RF propagation, interference, and spectrum-coexistence simulations.
This role directly supports federal 5G and spectrum-sharing programs, analyzing inter-system interference between commercial 5G networks and incumbent federal systems (e.g., radar, satellite, and aeronautical services).
The ideal candidate is a builder, not a reviewer — someone who can develop scenarios, configure tools, run models, and quantify interference.
What You’ll Do
- Build, calibrate, and execute RF propagation and coexistence models using tools such as Atoll, Planet, or SEAMCAT, and interpret coverage and interference results.
- Perform link budget and Monte Carlo simulations to determine harmful interference probabilities (I/N, I/(S+N)), protection ratios, and exceedance metrics.
- Evaluate and compare RAN performance and spectrum sharing scenarios across 4G/5G and federal spectrum bands (e.g., 3.1–3.45 GHz, C-band, X-band).
- Develop and automate analysis workflows using MATLAB, Python, or other modeling frameworks.
- Validate 5G RAN features in coexistence contexts — Carrier Aggregation, DSS, mMIMO, beamforming, and TDD synchronization impacts.
- Author technical memos and summary reports that quantify interference risk and propose mitigation measures (e.g., EIRP control, sector blanking, antenna pattern shaping).
- Collaborate with NTIA, DoD, and DISA spectrum teams to test and refine coexistence methodologies.
- Conduct troubleshooting and data validation using tools such as Wireshark, QXDM, TEMS, or Actix.
Basic Qualifications
- U.S. Citizenship (required) for federal project eligibility.
- 10+ years of RF systems or wireless network engineering experience, with 5+ years in 5G or LTE RF analysis and simulation.
- Proven experience running and interpreting results from Atoll, Planet, SEAMCAT, or similar RF modeling tools.
- Hands-on experience performing interference and coexistence studies, link budgets, and system-level propagation analysis.
- Working knowledge of 3GPP Releases 15–18 (NR, DSS, CA, CoMP, mMIMO, beamforming).
- Solid grasp of signal-processing fundamentals (numerology, Doppler, CQI/BLER relationships).
- Proficiency in Python, MATLAB, or equivalent for simulation automation and visualization.
- Bachelor’s degree in Electrical, Telecommunications, or RF Engineering (Master’s preferred).
Preferred Qualifications
- Experience supporting DoD, NTIA, DISA, or FCC spectrum engineering projects.
- Familiarity with federal/commercial spectrum sharing frameworks (CBRS, 3.1–3.45 GHz, C-band).
- Knowledge of O-RAN / vRAN and cloud-based RAN environments (Docker/Kubernetes a plus).
- Prior authorship of technical reports or coexistence studies (e.g., protection-ratio analysis, harmful-interference evaluation).
- Active Secret or Public Trust clearance preferred.
Why You’ll Love It Here
- Contribute directly to national 5G spectrum-sharing and coexistence studies for defense and federal customers.
- Join a small, agile team where you design, simulate, and deliver the results yourself — not just review vendor output.
- Engage daily with senior spectrum engineers and federal partners shaping next-generation wireless policy and operations.
