Your mission

Are you a social media and digital marketing expert (m/f/d) who wants to turn breakthrough photonic computing technology into a brand people talk about? You are interested in working in a deep tech company and have the ability to transport highly specialized technology messages to our social media audience? Than Q.ANT is a great opportunity for you as a Senior Social Media & Digital Marketing Manager (m/f/d) to own our social media presence, grow our digital footprint across LinkedIn, X and beyond, and translate deep tech into engaging content for a global B2B audience.

As Senior Social Media & Digital Marketing Manager (m/f/d), you will own Q.ANT’s social media presence end-to-end and support the operative execution of the CEO’s personal social media channels in close coordination with the CEO Office.
