Working Student – Business Administration & Finance (f/m/d)

Who We Are

MOXZ is a Berlin-based deep-tech startup and spin-off from TU Berlin. We build customized ISAC

(Integrated Sensing and Communication) radios based on our patented technology. They transmit

data and sense their environment at the same time, delivering reliable connectivity and precise

positioning in a single device, without GPS or additional infrastructure. Our technology works where conventional wireless fails, especially in tunnels and mines. We are currently piloting our radios for positioning with a major European public transport operator. Founded in 2023, we are a small team of around 10 people building the future of wireless communication.

Your Role

As our working student in business administration, you will help us bring together tasks that are

currently spread across the team, and make our processes simpler and more efficient. You will start

by supporting finance and procurement, with the opportunity to take on more responsibility over

time. Working closely with the founders, you will help lay the foundations of our setup, from invoicing and liquidity planning to purchasing and the correct allocation of components to fixed assets, inventory and sold products. You are reliable and care about the details that make a business run. You will have plenty of room to shape the tools and processes we use as we grow.
