Staff Infrastructure Security Engineer

Credit Karma is a mission-driven company, focused on championing financial progress for our more than 100 million members in the U.S., Canada and U.K.  While we're best known for pioneering free credit scores, our members turn to us for tips as they work on their financial goals, including helping them monitor their credit, identity monitoring, searching for credit cards, shopping for loans (car, home and personal), filing their taxes with Credit Karma Tax and growing their savings* -- all for free. Credit Karma has grown significantly through the years: we've added more than 70 million members in the last five years alone and now have more than 1,100 employees across our offices in San Francisco, Charlotte, Los Angeles, Leeds, London and soon Oakland.

Security is a core value at Credit Karma. We help millions of people better manage their credit. Safeguarding their sensitive information is critical to our continued success. From the CEO down to each individual engineer, everyone views security as a personal responsibility.
