About Us
We're a rapidly growing wealth management firm on an ambitious journey to 5x growth over the next 6 years. Our small but mighty data team of 3 has built a cutting-edge platform using open-source technology on AWS, delivering everything from real-time dashboards to innovative web applications. We believe in shipping fast, learning quickly, and building tools that advisers and clients actually love to use.
The Opportunity
We're looking for a Full-Stack Engineer to join as our 4th team member and own the delivery of critical web applications. This is a hands-on role where you'll build tools that directly impact adviser productivity, operational efficiency, and client experience.

· Develop robust APIs and backend services integrated with our internal and 3rd party systems

· Solid SQL skills and experience with data integration
· Experience translating vague business requirements into working software
· Track record of delivering projects on aggressive timelines
· Comfortable working autonomously with minimal supervision
· Excellent communication skills with non-technical stakeholders
