Secondly it’s to ensure viewer/buyer experiences are optimized to ensure high conversion and low support inquiries across devices.

Your profile

  • You must be autonomous, with strong drive for results, able to work in a team within a fast-paced start-up. Very good spoken and written English is a must.
