Role

Feel a strong sense of ownership - driving the product from early concepts to launch and beyond, while keeping the user experience front and center in every decision
Drive architectural decisions and define the technical direction, while fostering alignment across the team and mentoring engineers toward those goals
Collaborate closely with product managers, designers, and other engineers to create intuitive, lovable experiences

Our take

Frustrated by the archaic, fee-laden banking services offered to entrepreneurs, the founders of Mercury set out to create a better solution. They envisioned a platform that was dynamic, tech-driven, and free from unnecessary fees.

Mercury delivers on this vision by automating business payment processes, offering FDIC-insured accounts, and providing full API access, empowering entrepreneurs with greater control and efficiency. This approach stands in stark contrast to traditional startup banking, which often burdens young businesses with high fees and limited functionality.

By prioritizing user experience and offering a free service tier, Mercury has attracted over 100,000 businesses and achieved a $1B valuation in 2021. As a rising unicorn in the stagnant world of startup banking, mercury is poised for continued growth, constantly adding new features and expanding its team to further disrupt the industry.
