Beatgrid is redefining cross-media measurement with breakthrough deep-tech innovation. Built on our own Automatic Content Recognition (ACR) technology, the world’s only hybrid of audio fingerprinting and watermarking, we provide deterministic, privacy-first insights that reveal true ad effectiveness across TV and digital platforms like Netflix and YouTube.

Trusted by global leaders such as Google, Amazon Prime, Disney+, and Netflix, we set a new standard for accuracy and transparency in an increasingly fragmented media landscape.

You’ll build and scale up our measurement apps, developed on Kotlin Multiplatform for shared logic while maintaining native Android and iOS layers. You’ll also contribute to the backend systems that power them. You will work with the latest technologies, contribute to innovations no other company has built, and enjoy the pace and excitement of an ambitious deep-tech company.
