Our mission at Mimi is to give everyone the best possible hearing experience and protect your hearing health. We are the world’s leading provider of hearing-based audio personalization and digital hearing test technologies. Our team has developed a biologically-inspired and proprietary audio processing technology that knows how well you hear in order to personalize your listening experience and prevent hearing damage. Mimi’s technology can be integrated into consumer electronics devices, such as headphones, smartphones, TVs, in-flight entertainment systems and a range of systems and platforms.

Our Team

We are an eclectic bunch of over 60 people of 20 different nationalities — including sound engineers, product designers, researchers, scientists, and software developers, all working together to create a world where hearing ability is no barrier to amazing, personalized sound. At Mimi, diversity is our strength. We’re based in Berlin — start-up capital of the world, and we’re invested not only in products that help the world hear better, but in people who make our culture smarter, richer, and more human. We are committed to creating a culture that nourishes personal growth as a basis for company growth. We are a learning organization; we love to work with people who take initiative and are not afraid to try, fail and try again.

This can be your workplace

Yearly education budgets, flat hierarchies, flexible working environments, regular working from home opportunities, flexible holiday policies and team events… We do what we can to keep our teams engaged and thriving. But, no ‘perk’ is more rewarding than the experience of working side by side with a group of brilliant, passionate people creating something meaningful together. We’re growing fast and always on the lookout to hire talented, driven, and friendly folks, who are ready to meet new challenges and realize new dreams with us.
