Investment Support Specialist

Mercury is building the complete finance stack for startups, one where founders spend less time thinking about money infrastructure and more time building their companies. We've spent years earning the trust of over 300,000 businesses on the banking* side. In 2026 we are launching  Mercury Treasury, we're expanding the team to match.
