44 Monstro Jobs Hiring Near You

Monstro is the operating system for governed financial intelligence. We build governance and intelligence infrastructure that enables artificial intelligence to operate safely, explainably, and at institutional scale.

We exist because the level of financial guidance historically available to a small group should be accessible to many more people. By combining AI with deep institutional infrastructure, we help financial institutions deliver more personalized, responsible, and life-changing financial support to millions of individuals.

We're building mission-critical systems in a highly regulated domain, and we care deeply about doing it right. If you're motivated by meaningful problems, high standards, and shaping infrastructure that improves financial outcomes, you'll feel at home here.

Monstro is hiring a hands-on SVP Head of Finance & Accounting to own the entire finance function: accounting, close, back-office operations, client billing, vendor cost management, reporting, and compliance.

As the founding finance hire, you'll build the finance function from the ground up - creating the infrastructure required to support Monstro's growth deliberately and ahead of the demand.

The scope is broad by design. This person keeps the books, runs close, and manages back-office operations - while simultaneously architecting the control systems that govern client revenue recognition, vendor and API cost attribution, and spend compliance in a regulated fintech environment. At Monstro, finance is operational infrastructure, not administrative support.

This role exists to set a solid foundation for every financial and accounting transaction at Monstro. The primary objective is exhaustive, highly accurate, and scalable systems to manage spend - across every function, vendor, and client relationship.

Client billing is a major focus - revenue is usage-based, contracts are complex, and institutional clients require precision. Vendor cost management is equally critical, particularly API and data usage, which are variable, high-volume, and directly tied to product delivery. Monstro's internal controls must reflect the same standards as the banks and financial institutions we partner with - the reporting and compliance of that spend must be airtight.

Success is measured by the quality and integrity of the financial infrastructure this person builds - and how well it holds as Monstro scales.
