We're looking for Full-Stack Software Engineers who want to help businesses of any size move money worldwide. You will contribute to APIs, banking infrastructure and financial workflows that ensure our customers can adopt and scale with Modern Treasury.

Whereas most SaaS companies move data, we move money. Our systems must scale to high volumes, with high accuracy and high reliability. Engineers at Modern Treasury design thoughtful design APIs, implement resilient processes, and choose infrastructure that prioritizes fault tolerance and long-term maintainability over chasing latest trends.

Our application is powered by Ruby on Rails, Postgres, Redis and ParadeDB. As of today, we are on the latest version of each technology. Github and typical CI/CD automation is used for deployments to AWS. While engineers have specialties, engineers can easily contribute to all layers and components of the application without friction.
