NASA has a rare job opening for a new "Planetary Protection Office." Responsibilities do not include defending Earth from an impending alien invasion.
From the job listing:
Planetary protection is concerned with the avoidance of organic-constituent and biological contamination in human and robotic space exploration. NASA maintains policies for planetary protection applicable to all space flight missions that may intentionally or unintentionally carry Earth organisms and organic constituents to the planets or other solar system bodies, and any mission employing spacecraft, which are ntended to return to Earth and its biosphere with samples from extraterrestrial targets of exploration. This policy is based on federal requirements and international treaties and agreements.
