About this role
40,000 buyers. 20+ countries. One Salesforce org carrying all of it. You own the two-way sync between Salesforce and our core platform, plus the migration off Aura and Visualforce that has been waiting for someone senior enough to do it properly.
Location: Remote from anywhere in Brazil, on a freelance contract. Your day starts at 7:00 AM Brazil time (12:00 CET) for overlap with the European team.
