Solution Architect

We are looking for a Solution Architect to drive one of our projects built on Fintech.Core, our modular white-label fintech platform. The ideal candidate will lead an engineering team, design scalable and reliable architectures, and take ownership of both the technical quality and the engineering team’s efficiency within a major client deployment.

In addition to the core project responsibilities, the architect may participate in company-wide pre-sale initiatives, contributing to technical discovery, shaping solution proposals, and presenting architectural concepts to prospective clients.
