Senior Software Engineer
Computer Software | Greater Atlanta Area, US
I design, implement, and maintain security and electronic payment system software for the Petroleum & Convenience Retail department of NCR Retail (formerly Radiant Systems). This involves creating low level network interfaces to electronic payment processors such as First Data, Heartland Payment Systems, and Chase Paymentech. Beyond network programming, I create the security infrastructure keeping cardholder data safe. This includes strong cryptographic systems, authentication mechanisms, forensic analyses, conducting training, and writing documentation. This allows our software to pass frequent PA-DSS validations, enabling merchants to easily maintain PCI-DSS compliance.
