About the Role

As an Implementation Manager, you will take full ownership of the merchant onboarding and integration journey after pre-sales closes the technical design.

You will prepare integration packages, build go-live plans, answer technical questions, coordinate internal teams for product developments, and ensure high-quality and on-time merchant go-lives.

You will be measured not only by the speed of onboarding but also by the quality of the go-live — making sure every flow, exception, and integration need is correctly addressed and tested.

Responsibilities

  • Prepare and deliver a full Statement of Work (SOW) for the merchant, including:

  • Test credentials

  • API documentation

  • Integration diagrams

  • Any project-specific technical material

  • Define and align a Go-Live Timeline:

  • Work with the merchant to break down the project into phases (if needed)

  • Identify key milestones, dependencies, and risks

  • Be the merchant’s main technical point of contact during integration:

  • Support the merchant’s technical team with questions, troubleshooting, best practices, and clarifications

  • Own and push timelines:

  • Ensure the merchant and internal teams are meeting the project deadlines

  • Actively manage risks, delays, and escalations

  • Collaborate closely with the Product and Engineering teams to:

  • Escalate and prioritize integration blockers

  • Follow up on new developments and product features required by the merchant

  • Build UAT (User Acceptance Testing) matrices:

  • Internal-facing UAT matrices to align Product teams on the development acceptance criteria

  • Merchant-facing UAT matrices to ensure the merchant tests every critical payment flow and use case

  • Drive a clean go-live process:

  • Monitor launch success

  • Ensure operational readiness of all flows (payment success, failure handling, refunds, tokenization, etc.)

  • Post-go-live support:

  • Stay engaged for 3 weeks after go-live to ensure stability before handing off the account.


  • Requirements

  • 3+ years of experience in technical project management, technical account management, merchant integrations, or technical consulting — preferably in Fintech, Payments, or SaaS companies.

  • Strong technical understanding of payment integrations (APIs, SDKs, payment gateways, fraud vendors, alternative payment methods).

  • Exceptional project management skills: timeline creation, stakeholder management, risk mitigation.

  • Client-facing experience: comfortable leading technical conversations with merchant engineering teams.

  • Organized and proactive: capable of running multiple integration projects at the same time.

  • Experience with UAT planning and test case validation.

  • Fluent in Spanish and English.

  • Startup or high-growth tech environment experience is a plus.
