RF Engineer

Airbase builds the software platform for radio frequency spectrum licensing, coordination, and intelligence. Backed by a16z, we are a fast-moving, dual-use startup transforming wireless communication from a static, analog bottleneck into a dynamic, software-defined advantage.

Today, the world’s most advanced hardware—from satellite mega-constellations to Army UAS swarms and Electronic Warfare systems—is grounded by 20th-century paperwork. Spectrum coordination relies on fragmented databases, missing systems of record, and decades of static PDFs. Airbase is fixing this. We’ve built novel AI pipelines to digitize this analog bureaucracy and translate it into a software-defined, machine-readable data layer. We are transforming the spectrum from a static bottleneck into a dynamic advantage, delivering machine-speed tactical deconfliction for the military and automated licensing for commercial innovators.
