Basically we're changing how a city breathes and moves with sustainable and innovative ways to improve urban travel options for everyone. We're on a one-way trip to create a world with less pollution, less traffic jams and more ways to explore your city without leaving an impact. Climate-neutral TIER Mobility is Europe’s leading provider of micro-mobility, with a mission to change mobility for good.

Since we opened our doors in October 2018, +140 cities have chosen us across 15 markets. More than +950 people have joined us on our mission to change mobility for good. In November 2020, TIER successfully raised $250m in Series C funding to accelerate our ambitious plans, with investors such as SoftBank, Mubadala Capital, Northzone, and Goodwater Capital. 

The TIER Energy Network is an important part of our vision to change urban mobility for good. At our swapspots in partner shops across the city, users of electric vehicles can exchange empty batteries for charged ones. 

As a Sales Development Representative, your task will be to find partner shops where our customers can swap their Powerboxes.

The Powerbox is profitable for our partner shops, as TIER pays for the electricity costs and takes care of the maintenance.

The position is initially limited to the project period, with the option to extend.
