Founding Account Manager

About the Role

This is a rare founding-team opportunity to build and lead the Account Management function from the ground up at a fast-growing, early-stage fintech infrastructure company. As the first Account Manager hire, you will own the full post-sale lifecycle — from onboarding and integration through revenue ramp, upsell, and product launches — for a growing portfolio of US bank and global fintech customers.

You'll report directly to the Head of Growth and work closely with product, engineering, operations, and compliance teams. This role has direct, measurable impact on live revenue and shapes how the company scales its customer relationships for years to come. Visa sponsorship is available.

What You'll Do

• Define and build the Account Management function from scratch — processes, KPIs, success metrics, and tooling.

• Lead end-to-end customer onboarding and integrations post-contract signature, coordinating across product, operations, compliance, and engineering.

• Own day-to-day relationships with enterprise and institutional customers to accelerate revenue ramp, surface product feedback, and prevent churn.

• Design and execute upsell strategies; coordinate new product launches with cross-functional teams.

• Manage complex, senior stakeholder scenarios including C-suite executives, founders, and shareholders.

• Build automation and repeatable systems to minimize manual work and increase scalability across onboarding and account management workflows.

• Translate customer insights into actionable product feedback to directly influence roadmap prioritization.

• Travel globally as needed across the US, Europe, APAC, and LATAM to support customer relationships and commercial activities.
