• Nice-to-have skills: Prior experience in AdTech, knowledge of mobile attribution providers, and experience working in a pre-sales or customer-facing engineering role.

Your background should demonstrate an ability to handle ambiguity and a proactive approach to solving problems before they impact the client's bottom line.
