Physical Scientist - Geological Survey

All qualifications must be met by the closing date of this announcement-10/23/2026-unless otherwise stated in this vacancy announcement. To receive credit for experience, 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. Failure to adequately provide information needed to determine number of hours worked in each position may result in that time not being credited when evaluating qualifying experience. For periods of time that reflect military service, the DD-214 or Statement of Service is sufficient to meet the full and/or part-time hours requirement as the service dates will be reflected. Minimum Qualification Requirements: To qualify for this position, you must meet the following minimum qualifications: Basic Educational Requirement AND/OR Specialized Experience for the series to which you are applying. Basic Educational Requirements: In addition to the specialized experience requirements for this position, you must meet at least one of the following: A. Degree: physical science, engineering, or mathematics that included 24 semester hours in physical science and/or related engineering science such as mechanics, dynamics, properties of materials, and electronics. You must submit transcripts. -OR- B. Combination of education and experience: cducation equivalent to one of the majors shown in A above that included at least 24 semester hours in physical science and/or related engineering science, plus appropriate experience or additional education. You must include hours per week and transcripts. -AND- To qualify for this position at the GS-11 grade level: Specialized Experience Requirement: 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 defined as demonstrated experience: examples of such experience may include supply chain analysis, economic and econometric modeling, industrial ecology, material flow and trade analysis, and/or life cycle assessment, that is specific to non-fuel mineral commodities. This work would have required the individual to select and make minor adaptations to procedures and accepted practices and handle unexpected conditions arising in the normal course of the work. At this level, physical scientists have the ability to independently perform moderately difficult and responsible scientific work. You must include hours per week worked. -OR- Education: Successful completion of at least Three years of progressively higher level graduate education (54 semester hours, 81 quarter hours or the equivalent) leading to a Ph.D. degree in physical science or other directly related field of study or Ph.D. or equivalent doctoral degree in physical science or other directly related field of study if it provided the knowledge, skills and abilities necessary to do the work of the position to be filled. . You must include transcripts. -OR- Combination of education and experience: a combination of successfully completed graduate level education, as described, above that is beyond the second year of progressive graduate study and professional experience, as described above. To combine education and experience, first take the percentage of qualifying education required for the grade level. Then take the number of months of full-time experience and divide by 12 months. Add the percentages together. The total must equal at least 100 percent to qualify. You must include hours per week and transcripts. To qualify for this position at the GS-12 grade level: Specialized Experience Requirement: you must possess at least one full year of specialized experience equivalent to the GS-11 level in the Federal service (obtained in either the public or private sectors). Specialized experience is defined as demonstrated experience: Examples of such experience may include supply chain analysis, economic and econometric modeling, industrial ecology, material flow and trade analysis, criticality assessments, life cycle assessment, supply risk assessment, supply and demand scenario development, and/or uncertainty analysis that is specific to non-fuel mineral commodities. This work typically involved conventional methods and techniques though it required going beyond clear precedents and required adapting methods to the problems at hand and interpreting findings in terms of their scientific significance. At this level, physical scientists have the ability to independently perform scientific work of considerable difficulty. You must include hours per week worked. To qualify for this position at the GS-13 grade level: Specialized Experience Requirement: you must possess at least one full year of specialized experience equivalent to the GS-12 level in the Federal service (obtained in either the public or private sectors). Specialized experience is defined as de
