Onboarding Specialist (Client Onboarding & Payment Operations) - Argentina

AtPaystone, we’re looking for an Onboarding Specialist who can confidently manage a high-volume onboarding pipeline while maintaining accuracy, urgency, and strong follow-through.

In this role, you’ll manage merchant payment applications from submission through approval and activation, working closely with internal sales teams, acquirers, and operational stakeholders to ensure applications are processed accurately and within established SLAs. You’ll review documentation, troubleshoot discrepancies, coordinate follow-ups, and help merchants move smoothly through the onboarding process.

• Manage ongoing follow-ups, status updates, and active onboarding workflows.
• Document and share onboarding process updates, acquirer mandates, and operational changes with the team.
• Identify opportunities to improve onboarding workflows, SOPs, and overall operational efficiency.

• Post-secondary education in Business Administration, Operations, or a related field is considered an asset.
• 4+ years of experience in client onboarding or merchant onboarding within a fast-paced environment.
• Proven ability to manage a high-volume onboarding pipeline independently while balancing multiple active files and ongoing follow-ups
