Join our team at Modern Treasury as a Full-Stack Software Engineer, empowering businesses of all sizes to facilitate global money movement. You will play a key role in developing APIs, banking infrastructure, and financial workflows that enable our customers to seamlessly adopt and scale with our solutions.
While many SaaS companies focus on data transfer, we focus on financial transactions. Our systems are designed to handle high volumes with exceptional accuracy and reliability. As an engineer at Modern Treasury, you will create thoughtfully designed APIs, implement robust processes, and select infrastructure that emphasizes fault tolerance and long-term maintainability over fleeting trends.
Our application utilizes a modern tech stack, including Ruby on Rails, Postgres, Redis, and ParadeDB, and we maintain the latest versions of these technologies. We employ GitHub and standard CI/CD automation for deploying to AWS. Although our engineers have areas of specialization, we encourage contributions across all layers and components of the application.
ABOUT MODERN TREASURY
Modern Treasury provides a reliable infrastructure for money movement, enabling teams to launch and scale payment experiences in days rather than months. With premier developer tools and a single API for fiat and stablecoins—along with integrated compliance, ledgering, and reporting—Modern Treasury allows businesses to move money instantly, reliably, and at scale.
Over $750 trillion is processed across banking rails each year. However, the technology supporting these rails has lagged behind the digital transformation seen in other industries. Recognizing this significant opportunity, our founders established Modern Treasury in 2018 to support the world's largest industries and money movers. Today, we proudly serve companies in vital sectors such as real estate, healthcare, insurance, education, and financial services.
