About Tradeshift
Tradeshift is a unicorn in the fintech industry. We are disrupting a typically stagnant environment by connecting companies of all sizes and providing them with the platform and network needed to create value from old processes like procurement, invoicing, payments, and workflow. We recognize that business is both messy and social - two revelations that have driven the development of Tradeshift, a platform for all your business interactions.

Our team believes in an integrated approach to application security, and that prevention is better than a cure. We also believe that communication skills and the ability to help others can amplify the impact of an engineer 10x.  We take security very seriously and work very hard to include it throughout our software lifecycle from the design process all the way through how we operate the platform.
