This job is for a lead park ranger focused on protecting visitors and resources in a national scenic riverways park in Missouri, involving supervision of law enforcement and safety operations.
It suits experienced professionals with a background in park protection or law enforcement who enjoy outdoor work and leading teams in natural settings.
Expect a mix of fieldwork, administrative duties, and ensuring public safety in a remote park environment.

The position to which you will be appointed is subject to a financial disclosure reporting requirement and you will be required to complete a new entrant Confidential Financial Disclosure Report (OGE Form 450) within 30 days of your appointment.
As a condition of employment for accepting this position, you will be required to serve a 1-year probationary period during which your fitness and whether your continued employment advances the public interest will be evaluated.
This probationary period is an extension of the appointment process and therefore requires the agency to determine if continued employment would advance the public interest, meet the organization goals and mission of the agency, and/or otherwise promote the efficiency of the service.
In determining if your employment advances the public interest, the agency will consider: your performance and conduct; the needs and interests of the agency; whether your continued employment would advance organizational goals of the agency or the Government; and whether your continued employment would advance the efficiency of the Federal service.
Under applicable law, the employment of an individual serving a probationary period automatically terminates when that period ends unless the agency affirmatively certifies, in writing, that the individual's employment should continue and that their appointment should be finalized.
In the absence of agency action to affirmatively certify continued employment beyond the probationary or trial period, such appointments are terminated.
Upon completion of your probationary period your employment will be terminated unless you receive certification, in writing, that your continued employment advances the public interest.
