Summary

All qualifications must be met by the closing date of this announcement - 10/30/2026-unless otherwise stated in this vacancy announcement. Competitive candidates must also meet Time-in-Grade requirements as defined in 5 CFR 300, Subpart F. For current Federal employees, if hours worked per week are not included on your resume, you must submit a non-award SF-50 as part of your application to be used to validate your work schedule and determine the amount of specialized experience that you will be granted. An award SF-50 will not be acceptable documentation for which to consider your amount of qualifying experience. For periods of time that reflect military service, the DD-214 or Statement of Service is sufficient to meet the work schedule requirement as the service dates will be reflected. 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. Minimum Qualification Requirements: To qualify for this position, you must meet the following minimum qualifications: Basic Educational Requirements Geologist GS-1350: In addition to the specialized experience requirements for this position, you must meet at least one of the following: A. Degree: A degree in geology, plus 20 additional semester hours in any combination of mathematics, physics, chemistry, biological science, structural, chemical, civil, mining or petroleum engineering, computer science, planetary geology, comparative planetology, geophysics, meteorology, hydrology, oceanography, physical geography, marine geology, and cartography. You must submit transcripts. -OR- B. Combination of education and experience: course work as shown in A above, plus appropriate experience or additional education. Acceptable experience may have been gained through geological field or laboratory work that provided a means of obtaining professional knowledge of the theory and application of the principles of geology and closely related sciences, e.g., geophysics, geochemistry, or hydrology. Such work generally must have involved making close observations, taking samples, handling various types of instruments and equipment, assembling geologic data from source materials, and analyzing and reporting findings orally and in writing. In some situations, professional scientific experience in other fields may be accepted in part as professional geological experience. Such experience must have been preceded by appropriate education in geology or by professional geological experience, must have contributed directly and significantly to the applicant's professional geological competence. To receive credit for geological experience obtained in positions that are not full-time professional geological positions, the applicant is responsible for indicating clearly the actual time or percentage of time devoted to geologic duties within such positions, and for giving adequate descriptions of the geologic functions.) You must provide transcripts and hours worked. -AND- To qualify for this position at the GS-11 grade level: Specialized Experience: To qualify, you must possess at least one full year of specialized experience equivalent to the GS-09 level in the Federal service (obtained in either the public or private sectors). Specialized experience is experience that equipped the applicant with the particular knowledge, skills, and abilities to perform successfully the duties of the position, and that is typically in or related to the work of the position to be filled. To be creditable, specialized experience must have been equivalent to at least the next lower grade level in the normal line of progression for the occupation in the organization. Specialized experience is defined as demonstrated experience: in work planning and coordination during preparation, compliance, construction, and post construction monitoring of major infrastructure projects; geologic mapping, field inventory, monitoring, and protection of sensitive paleontological resources; geological evaluation of borehole data; evaluation and interpretation of large geophysical and LiDAR data sets; identification, evaluation, and potential migration of geohazards (e.g., rockfalls, debris flows); identification and evaluation of threats and vulnerabilities to resources, infrastructure, personnel, and visitors; provide geological, geophysical, and paleontological data and reports; lead efforts, plan studies, lead and assist field crews, conduct field studies, and collect and interpret geological data. You must include hours worked. -OR- Education: Successful completion of at least three years of progressively higher-level graduate education leading to a Ph.D. degree or Ph.D. equivalent doctoral degree. You must include transcripts. -OR- Combination: Successfully completion of a combination of graduate level education and specialized experience. Note: only education in excess of the amount required for the next lower grade level (GS-9 is 2 years of progressively higher-level graduate education leading to a master's degree or master's or equivalent graduate degree) may be combined with experience. For example, an applicant with 6 months of appropriate experience equivalent to GS-9 (50 percent of the experience requirement for GS-11) and 27 semester hours of appropriate graduate education (50 percent of the education requirement for GS-9, in excess of that required for GS-7) would be qualified for a GS-9 position (assuming that there is no evidence that the attended college or university requires more than 18 semester hours as equivalent to a year of graduate study). You must provide transcripts and hours worked. Volunteer Experience: Experience refers to paid and unpaid experience, including volunteer work done through National Service programs (e.g., Peace Corps, AmeriCorps) and other organizations (e.g., professional; philanthropic; religious; spiritual; community, student, social). Volunteer work helps build critical competencies, knowledge, and skills and can provide valuable training and experience that translates directly to paid employment. You will receive credit for all qualifying experience, including volunteer experience.

Major Duties

Some of the major duties you will perform include but are not limited to the following: Plan, coordinate, manage, and lead comprehensive geologic monitoring projects and studies. Collect, manage, analyze and interpret geologic data using standard and novel methods and procedures. Develop, modify, and utilize spatial and relational databases and related applications to maintain and synthesize geologic data for planning and analysis. Develop proposals for scientific investigations related to the geological sciences, including scopes of work, expected benefits and work products, timelines, and budgets. Write, communicate, and publish reports of geologic findings in internal or external reports, presentations, recommendations to resource managers, or scientific journal publications.

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.
