Senior Frontend Engineer

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.

We're building a next-generation financial management platform for banks, and we're looking for a Senior Frontend Engineer to help us create a number of user interfaces supporting our clients and operations. You'll shape how everyday customers interact with their finances through sophisticated AI-driven tools, delivering interfaces that are intuitive, performant, and built to the standards the financial industry demands.
