Principal Software Engineer

Towers Crescent (12066), United States of America, Vienna, Virginia

At Capital One, we're building a leading information-based technology company. Still founder-led by Chairman and Chief Executive Officer Richard Fairbank, Capital One is on a mission to help our customers succeed by bringing ingenuity, simplicity, and humanity to banking. We measure our efforts by the success our customers enjoy and the advocacy they exhibit. We are succeeding because they are succeeding.

Guided by our shared values, we thrive in an environment where collaboration and openness are valued. We believe that innovation is powered by perspective and that teamwork and respect for each other lead to superior results. We elevate each other and obsess about doing the right thing. Our associates serve with humility and a deep respect for their responsibility in helping our customers achieve their goals and realize their dreams. Together, we are on a quest to change banking for good.

Principal Software Engineer

Our team is a small, entrepreneurial group focused on leveling the playing field for small businesses. We believe that small businesses should be able to have access to the same resources, financing, and expertise that larger businesses do. We believe that small businesses shouldn't have to choose between slow, cumbersome banks with attractive rates, or modern fast online lending at exorbitant rates.

Do you want to be part of a team launching a better way for small businesses to gain control of their cash flow? Do you want to work in a fast-paced new product development shop? Does the idea of taking a rough MVP and iterating it to product-market fit using customer feedback and your expertise excite you? If so, we want you!
