An FTPS developer is responsible for creating, managing, and maintaining secure file transfer protocols (FTPS). They ensure the secure transmission of data over a network by implementing encryption techniques and secure sockets layer (SSL) certificates, thus protecting sensitive information from unauthorized access. Their work also involves troubleshooting FTPS issues, optimizing transfer speeds, and integrating FTPS with other systems. They often collaborate with cybersecurity teams to ensure compliance with data privacy regulations. Additionally, they may provide technical support and training to users on FTPS usage, ensuring smooth and secure data operations within an organization.
