Implementation Manager
TLDR
Own merchant onboarding and integration, defining go-live plans and coordinating teams to ensure high-quality, on-time payments go-lives.
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.
