Requirements

What you’ll need

Some experience working with decision engines or rules-based platforms — ideally in financial services or fintech (tools like GDS Link, Experian PowerCurve, or Provenir are a plus, but not essential)
Comfort working with data — SQL experience is helpful, and some exposure to Python would be great
A methodical approach to problem-solving, with good attention to detail
Curiosity and a willingness to learn new tools and technologies
Good communication skills — you'll need to explain technical topics to people who aren't technical, and that's something we'll support you in developing.
