Staff Software Engineer (Marketplace Growth)

Growth Engineering sits at the intersection of product, marketing, engineering, analytics, and real-world operations

Your mission will be to help more consumers discover, adopt, and repeatedly use Zipline delivery

Some growth happens through software experiences such as onboarding flows, referral systems, promos, lifecycle messaging, attribution systems, and experimentation frameworks.
