Conditions of employment

• Must be a U.S. Citizen or National.
• Appointment subject to background investigation and favorable adjudication.
• Males born after 12-31-59 must be registered for Selective Service.
• Direct Deposit participation required.
• Must possess and maintain a valid driver's license throughout employment.
• You may be required to wear a uniform and comply with uniform standards. A uniform allowance will be provided.

As a condition of employment for accepting this position, you may be required to serve a 1 year probationary period to evaluate your fitness and whether your continuation of employment advances the public interest.

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 or trial 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.

This is a supervisory position that may require completion of a supervisory probationary period.

For all other applicants who are not current federal employees, your resume must state either "full-time" (or "40 hours a week") or "part-time" with the number of hours worked per week to ensure proper crediting of specialized experience.

To qualify for this position, you must possess one of the Basic Experience/Education Requirements for the 1301 series below AND you must possess the Minimum Qualifications (specialized experience) for the GS-12 grade level below.

Additional information

Additional vacancies may be filled using this job announcement.

First time hires to the Federal government normally start at the step 1 rate.

Physical Demands: The work regularly combines both office and field assignments. Field work requires physical exertion, such as long periods of standing, or recurring and considerable walking, stooping, bending, crouching, crawling, and climbing such as in regular and periodic construction activities and field inspections. Work may also include frequent lifting of moderately heavy items weighing less than 50 pounds. Field assignments may also drive motor vehicles to work sites, riding in watercraft, or hiking long distances into the Grand Canyon. Most field visits will be in remote areas and include overnight stays in remote locations.

Work Environment: The work is usually performed in an office setting. However, work time may also be spent periodically visiting field sites. Field site visits are typically performed in either an outdoor setting subject to weather changes, diverse terrain, and safety hazards associated with working around complex features and/or construction. Both settings may require the use of personal protective equipment. Safety precautions and protocols are observed at all times, and the scientist

complies with safety instructions and regulations and ensures individuals' safety by promptly reporting unsafe acts, unsafe conditions, and accidents to the supervisor.
