RF Signals and Data Analyst

Key Responsibilities

• Analyze RF event data using IQ derived representations such as spectrograms, waterfall views, PSDs, and metadata to identify, classify, and tag signals of interest.
• Help define and maintain a scalable maritime RF labeling taxonomy, including signal classes, confidence levels, rejection categories, and ambiguity handling.
• Build and refine high quality labeled datasets for machine learning, ensuring labels are technically defensible, consistent, and auditable.
• Identify and document recurring host vessel interference, platform artifacts, and environmental noise to support rejection library development.
• Collaborate with DSP and ML engineers to review false positives, false negatives, and edge cases, and improve labeling standards over time.
• Use available contextual data such as AIS, camera imagery, collection metadata, and sensor state to support signal interpretation when appropriate.

Qualifications

• 3+ years of experience in one or more of the following: RF signal analysis, SDR-based signal review, EW/SIGINT/ELINT analysis, RF dataset creation, or technical signal characterization.
• Practical experience working with RF data products such as IQ captures, spectrograms, waterfall plots, PSDs, or other time frequency representations.
• Experience working with structured labeling, annotation, classification, or technical review workflows where consistency and traceability matter.
• Comfort working in a Linux-based environment using Python, SDR tools, notebooks, or other RF analysis environments to inspect, organize, and process signal data.
• Ability to communicate clearly with engineers and translate signal observations into actionable labeling guidance.
• Experience in maritime RF environments or other cluttered, interference heavy operational environments.
• Understanding of how label quality, taxonomy design, multi-sensor context (for example AIS, EO/IR, or geolocation), and rejection categories affect downstream ML training and evaluation.
• Active clearance or ability to obtain and maintain a Secret clearance.
