Senior Frontend Engineer

About Monstro

Monstro is a governed AI platform for regulated financial institutions. We give banks and wealth managers a way to deliver trusted advice digitally — to every client, not just the top tier. Institutions already have the relationships, data, and context to understand each client. Monstro turns that understanding into advice. It gives every client the experience of a personal advisor: bringing together their full financial picture, identifying what matters, and delivering personalized guidance across investments, tax, retirement, insurance, legal, and more. For clients, that means clearer decisions, proactive support when life changes, and a better view of their financial lives. For institutions, it means deeper relationships, more clients served consistently, and more of each client's financial life managed in one place.

• Responsive Product Development in an AI-powered workflow
• Build and own features across our React applications, delivering polished experiences for our users and clients
