Senior Software Engineer II, Multiple Teams

Relay is a digital banking platform that gives self-made business owners the tools and know-how to be great with money—bringing clarity, confidence, and control to every dollar earned, so they can turn hard work into lasting success. We do this by replacing financial guesswork with real visibility, transforming cash flow from a constant source of stress into a clear signal owners can use to run stronger, more resilient businesses.

Our Engineering team is at the heart of building banking products that help millions of small businesses succeed. We're on a journey to reinvent banking, and we're looking for Senior Software Engineer IIs to help set the technical direction for how we get there. You'll take on our highest-risk, most ambiguous work, spot the problems that matter before anyone assigns them, and bring teams together around solutions that move the business forward.

This is a unique opportunity to shape architecture across interconnected systems, raise the engineering bar beyond your own team, and grow the next generation of technical leaders at Relay. If you're excited about building best-in-class fintech products and multiplying your impact through others, this is the role for you.
