The intern will work directly with full-time engineers on hardware bring-up, RF front-end validation, power and battery systems, antenna integration, and system-level troubleshooting. Responsibilities include bench testing, field testing support, documentation of electrical designs and test results, and iterative improvements to deployed sensor hardware. The role requires a strong foundation in electrical engineering fundamentals, comfort with lab equipment such as oscilloscopes and spectrum analyzers, and interest in RF systems, embedded hardware, or applied sensing. This is a hands-on engineering role embedded in active commercial and government deployments, with exposure to real-world constraints around size, power, reliability, and manufacturability.

Our sensors listen for drone control and video links, detect and classify them on the node, and stream detections to DroneView, our cloud platform for alerts and detecting drone activity. Our sensors run at utilities, ports, law enforcement agencies, universities and airports. Guardian RF is deployed across installations with the DoW. We are hiring a RF engineer. What You Will Work On Build and tune DSP detection and classification for drone RF links, improve track quality, and validate results against recorded field data. Configure antennas, filtering, LNAs and amplifiers for individual deployments, including filtered frontends that improve track fidelity at noisy urban sites. Develop link budgets and cascade analyses, measure hardware with VNAs and spectrum analyzers, and validate performance with real drones at deployment sites. What We Are Looking For A college senior or recent graduate in electrical engineering or a related field, with coursework in signals and systems, DSP, communications, electromagnetics or microwave engineering. Experience using a VNA, spectrum analyzer or SDR in a lab or internship. Programming experience in Python and/or C/C++. MATLAB experience is also welcome. Someone who learns by building and testing and wants ownership on a small engineering team. Helpful extras include an RF internship, a ham license, SDR projects using HackRF, USRP or GNU Radio, drone experience, antenna or PCB design, or the ability to obtain a US security clearance.
