Backend Software Engineer
Job description
About the role
Guardian RF is building next-generation drone detection systems to protect critical infrastructure, national security, and public safety. Our passive RF-based platform provides real-time situational awareness by detecting both compliant and non-compliant drones and integrating directly with security and law enforcement systems.
This role is primarily a full-time, in-person position based in Washington, DC, where close collaboration with our RF engineers and hardware team is essential. That said, we will consider strong candidates for remote work depending on experience and fit.
As a backend engineer, you’ll design and build scalable services to process large volumes of RF data, develop APIs for integrations, and help shape the foundation of our distributed system. You’ll work closely with RF engineers, data scientists, and front-end developers to deliver mission-critical technology that has real-world impact.
About Guardian RF
Guardian RF develops passive RF-based drone detection systems to protect national security, critical infrastructure, and public safety. Our systems provide continuous airspace monitoring, detect compliant and non-compliant drones, and integrate seamlessly with security and law enforcement operations. We work with the U.S. Air Force, state Departments of Transportation, law enforcement agencies, and commercial partners to safeguard sensitive sites ranging from airports to stadiums.

Our Story
Guardian RF builds passive, radiofrequency-based drone detection systems to counter the rise of low-cost commercial drones threatening U.S. national security. Off-the-shelf platforms now deliver ISR, contraband, and payloads while operating below radar coverage and beyond line-of-sight. These systems—often under $1,000—can neutralize multi-million-dollar assets. Scalable detection demands sensors that meet the threat in cost, size, and speed. Our systems are hardened for real-world deployment across military bases, public safety agencies, and critical infrastructure. We operate under an AFWERX Direct-to-Phase-II SBIR with the 30th Security Forces Squadron at Vandenberg Space Force Base. Our technology is fielded by law enforcement, integrated into fortune 500 commercial security teams, and selected for Falcon Peak 25.2—DoD’s flagship counter-UAS exercise. Scout is a passive RF sensor that detects and classifies drone control signals—including modified variants of DJI, Crossfire, and ExpressLRS—at standoff ranges. Mosaic extends coverage into austere environments, enabling low-altitude monitoring of non–Remote ID drones without active emissions or mesh dependency. All systems integrate with TAK and operational APIs, and are managed through GRF-SECURE for live alerting and forensic review. Guardian RF is U.S.-built, cost-aligned, and designed for persistent defense of the homeland.
