Do you want work at Mobbeel?
More than a decade ago, during the exciting heyday of web 2.0, five friends from Cáceres took a courageous step. While working at IBM, they participated in a Google competition for an iris recognition application that would later become the world’s first mobile biometrics project. The project achieved overwhelming success, and its founders were faced with a pivotal decision: continue as developers at a large company or pursue their entrepreneurial dream.
In July 2009, Mobbeel was born, a project that recognized no boundaries and aimed to enhance the security of digital transactions worldwide. Now, 14 years later, we continue to dream with the same fervor we had back then, striving to combat fraud in identification processes.
With our products, you can perform impressive tasks such as recognizing your voice, face, fingerprint, or signature using your mobile phone. You can also open a new bank account by scanning your ID and verifying your identity through facial recognition, or sign a legally valid contract on your tablet within seconds, utilizing the biometric features of your signature.
To continue our growth and develop even more amazing technological products, we seek the most creative and intelligent individuals to collaborate with us. We are a small, dedicated team that embraces daily challenges with enthusiasm.
In 2009, we were pioneers on a global scale in mobile biometrics development, and in 2024, we aim to maintain our position at the forefront of technology.
