Solutions Architect

Modern Treasury is hiring a Solutions Architect to design and guide the implementation of complex payment systems for our customers.

You will work closely with Sales Engineers and Technical Account Managers in the post-sale process to lead deep discovery into customers’ technical, financial, and operational needs. You will use this to design and guide the implementation of reliable money movement systems using Modern Treasury’s APIs.

This includes whiteboarding solutions, producing detailed architecture and design documents, and guiding customer development teams through implementation and early production. You will own ledger design, including how funds are tracked, reconciled, and represented across systems.

You will act as a trusted advisor during critical build phases, debug complex issues with real financial impact, and partner closely with Engineering and Product to shape solutions and influence the roadmap.
