No its more like this:
Someone attempting to sue a federal employee, alleging that an act within the scope of the employee's employment constitutes a “tort,” must sue under the Federal Tort Claims Act (FTCA). FTCA is the exclusive remedy for persons seeking money damages for injury to or loss of property, or for personal injury or death, caused by negligent or wrongful acts or omissions of your acts as a federal employee acting within the scope of your office or employment. That Act confers immunity on the individual employee for work-related acts. So a FTCA federal lawsuit would ultimately be against the U.S. government rather than against you personally. Generally, you cannot be sued in state court for actions arising from your federal employment.
