Senior Backend Engineer


LabTwin is creating the next generation of digital lab tools for smart labs, starting with the world’s first voice-activated lab assistant. With LabTwin, scientists can collect data, access information, manage experiments and streamline documentation simply by talking. Using voice recognition and machine learning technology, LabTwin’s smart assistant simplifies data capture, structures valuable information, and integrates with lab instruments and informatic systems.

We are a strong multinational interdisciplinary team with a mission to empower scientists and are based in Berlin. Our voice-powered assistant is now used by scientists in 7 of the Top20 biopharma companies, as well as chemical companies, around the world.

  • A great work-life balance that we care about.

At LabTwin, we are building the first digital voice-powered lab assistant that aims to close the real-time documentation gap at the bench. It helps scientists document when their hands are busy by using voice, thus helping them focus on their work and not on tedious documentation. We believe that by simplifying lab documentation, we can contribute to creating more efficient, complete and high-quality research. Our mission is to accelerate scientific discovery and tackle the biggest challenges of our time. LabTwin is located at the center of medtech innovation in one of the world’s most cosmopolitan, cutting-edge
capitals: Berlin. This city attracts the brightest entrepreneurs and makers, many of which work at our HQ in Prenzlauer Berg.
