This is a high-craft, high-ownership role for someone who genuinely cares about how product feels in advisors’ hands. You will work directly with the founders, designers, and backend engineers to set technical direction across our Type Script codebase, raise the bar on design quality, and turn ambitious product ideas into shipped features fast.

You will own the surfaces where real advisors do real work, including the web product, the in-inbox extensions for Gmail and Outlook, and the mobile experience as we extend Vega across the full advisor workflow.## Responsibilities### Product engineering
