About The Position

You’ll work across the stack—frontend, backend, and infrastructure—to deliver highly reliable, secure, and intuitive software for a fast-growing financial services business. You won't just build features; you will architect the systems that power our industry-leading platform, working at the intersection of sophisticated frontend experiences and robust, scalable backend services. Our Independent Financial Advisor platform handles sensitive data and powers critical workflows, including real-time commission reporting, secure document management, and notifications. You’ll help shape both the technical direction and day-to-day execution of the platform, balancing speed, quality, and long-term maintainability. Experience in financial services is a plus, but not required.
