The Smithsonian Astrophysical Observatory (SAO) is at the forefront, internationally, of the scientific exploration of the universe. SAO combines its resources with those of the Harvard College Observatory to form the Harvard-Smithsonian Center for Astrophysics (CfA). The CfA is the best-known astrophysics center in the world. Its programs range from ground-based astronomy and astrophysics research to space-based research, the engineering and development of major scientific instrumentation for space launch and use in large ground-based facilities, and research designed to improve science education. The research objectives of SAO are carried out primarily with the support of Government and Smithsonian Institution funds, with additional philanthropic support. Government funds are in the form of Federal appropriations or the form of contracts and grants from other agencies. In contrast, Institution funds are available to SAO through grants from the Institution's Restricted Funds, Special Purpose Funds, Bureau Activities, Business Activities, and non-Federal contracts and grants.

This is the position of Astrophysicist, Radio and Gastronomy Division, Smithsonian Astrophysical Observatory (SAO), Cambridge, MA. The position is charged with technical and scientific responsibility for formulating and conducting developmental research in radio astronomy, exceptionally long baseline interferometry, and the astrophysics of supermassive black holes. The work will include the development of advanced radio telescopes; the proposing, planning, and designing of observing programs; the analysis and interpretation of observational radio data; and the publication of significant scientific results.

• Formulate and conduct unique and original programs of independent astrophysical research, especially in the areas of radio astronomy, with an emphasis on exceptionally long baseline interferometry (VLBI) observations and the astrophysics of supermassive black holes (SMBHs). Conceive, plan, and conduct observations, and develop techniques for data reduction and analysis. Participate with other Division scientists in the conception, development, and application of advanced VLBI arrays, technology, and associated algorithms and methodologies, particularly in high-frequency VLBI. The primary focus will be on the EHT/ngEHT projects, but duties will include investigation of new opportunities as they arise. Lead and participate in the development of astrophysical software for the simulation, calibration, analysis, and interpretation of radio interferometric data. Maintain software in publicly available repositories.
• Prepare papers describing research results for publication in scientific or technical journals and presentation at scientific or technical meetings, conferences, and within the CfA. Attend professional meetings for the purpose of presenting new results and participating in the discussion of related efforts by other scientists. Referee papers submitted to scientific journals. Supervise and mentor, as appropriate, research interns, undergraduate and graduate students, and postdoctoral researchers. Organize, plan, and supervise the activities of mentees, advising on projects and priorities, establishing deadlines, monitoring progress, and reviewing work. Lead and support the development of proposals for research funding.
• Conducts advanced astrophysics research involving stellar, galactic, or cosmological phenomena. Designs and executes complex investigations integrating theoretical modeling, simulation, and analysis of observational data from space-based and ground-based instruments. Develops and refines scientific models and algorithms to characterize astrophysical processes such as radiation transport, stellar evolution, high-energy particle interactions, or galactic dynamics. Validates models against mission data and peer-reviewed literature. Serves as a technical lead or co-investigator on major research projects or mission science teams. Defines research objectives, develops methodologies, and ensures scientific rigor and compliance with agency standards.
• Designs and evaluate scientific instrumentation concepts, including optical systems, detectors, spectrometers, interferometers, or cryogenic components. Provides authoritative input on calibration, data quality, and instrument performance. Prepares high-impact scientific publications and presents findings at national and international conferences. Contributes to agency scientific strategy through white papers, mission concept studies, and technical assessments. Provides expert consultation to engineers, scientists, and program managers on astrophysics requirements, data interpretation, and mission science implications. Advises on feasibility, risks, and scientific value of proposed research. Leads collaborative research teams of GS-07-13 scientists, postdoctoral researchers, and contractors. Provides mentorship, technical guidance, and quality assurance for research outputs. Manages research resources, including project budgets, data pipelines, computational assets, and external collaborations with universities, laboratories, and observatories.
• Perform other duties as assigned.

A) Degree in one or a combination of astronomy, physics, mathematics, space science or electronics, including course work in differential and integral calculus and 12 semester hours in astronomy or physics; OR B) A combination of education and experience equivalent to A above including at least 30 semester hours of courses equivalent to a major in any combination of astronomy, space science, physics, mathematics, and electronics with required course work as shown in A above.

A minimum of one year of specialized experience equivalent to at least grade 13 in the normal line of progression for this occupation such as the duties listed above.

• Expert knowledge of astrophysics, including stellar, galactic, or cosmological processes; radiation physics; high-energy astrophysics.
