Onboarding Specialist

Onboarding Specialist Guiding Merchants from Sales Close to Go-Live Full-Time | Fenton, MO or Remote FLEX Payment Solutions is seeking an organized, highly motivated, and detail-oriented Onboarding Specialist to join our growing team. This is a newly created position — a chance to help build, develop, and improve our onboarding processes as the role evolves.

You'll report to our Director of Compliance (a reporting structure that may change as the Compliance team grows), and you can work from our Fenton, MO office or remotely.

About the Role

You'll guide each new Merchant through onboarding — from Sales close, through completing the FLEX application, to full approval and activation. You'll be the Merchant's primary point of contact for applications and documentation, make sure every file is complete and accurate before it goes to Underwriting, and keep our Sales team informed of progress through Hub Tracker.

(This role is not responsible for negotiating Merchant fee schedules.) What You'll Do Set expectations — explain the application process and why each piece of documentation matters. Collect and review — coordinate Merchant documentation and review every application for completeness, accuracy, and consistency before Underwriting.

Solve problems — work with Merchants, Underwriting, and Sponsor Banks to resolve questions and documentation issues. Keep everyone in the loop — monitor applications, communicate status, and provide daily updates to Sales, Risk, and Management. Manage the pipeline — own open pre-Underwriting tickets in FLEX CRM and track key metrics like Time-to-Approved and Time-to-Live.

Make it better — spot trends and bottlenecks, then design and implement new onboarding processes with our internal teams.
