2027 Jansky Fellowship Program The NSF National Radio Astronomy Observatory (NRAO) invites applications for the 2027 Jansky Fellowship Program. The Jansky Fellowships support outstanding early career scientists to conduct independent research which exploits NSF NRAO facilities and contributes to the NSF NRAO's mission. Since its inception over 60 years ago NRAO has been enabling forefront research into the Universe at radio wavelengths. In partnership with the scientific community, we provide world-leading telescopes, instrumentation, and expertise, train the next generation of scientists and engineers, and promote astronomy to foster a more scientifically literate society. NRAO operates four world-class research facilities: the Atacama Large Millimeter/submillimeter Array (ALMA), the Karl G. Jansky Very Large Array (VLA), the Very Long Baseline Array (VLBA), and the Green Bank Observatory (GBO), and is developing, and soon constructing, the next generation VLA (ngVLA) pushing the boundaries of the state of the art. We welcome applicants who bring innovative dimensions to the Observatory and to the field of radio astronomy. As a Jansky Fellow, you will have a unique opportunity to contribute to, and learn from, the development and delivery of the largest and most capable radio telescopes in the world. Jansky Fellowship Program supports projects in radio astronomy and multi-wavelength science, radio astronomy techniques, instrumentation, computation, and theory. Candidates with expertise or interest in NSF NRAO/GBO technological initiatives, such as very long baseline interferometry or Green Bank telescope upgrades, are encouraged to apply. Appointments may be made at the three internal NSF NRAO/GBO sites (Socorro/Albuquerque NM, Charlottesville VA, and Green Bank WV). Applicants should describe how their research or technical interests couple with NRAO's mission, telescopes or science. In compelling cases, a 'split appointment' Jansky Fellowship between a U.S. based university and an NRAO site, or a 'non-resident' Jansky Fellowship hosted at a university within the United States, may be offered. Non-resident Jansky Fellows are expected to develop a research program that fosters close ties with the NRAO and describe how residence at their proposed host university will accomplish this. Frequent and/or long-term visits to NRAO sites during the non-resident Fellowship are strongly encouraged. NRAO supports partial teleworking arrangements for scientific postdoctoral fellows. All application materials (except reference letters) must be received by 11:59 pm EDT on Wednesday, October 28, 2026. Only full applications will be considered. Significant non-adherence to the document rules (maximum number of pages, font size, margin size, etc) may jeopardize the application. Reference letters are due by 11:59 pm EDT on Wednesday, November 11, 2026.Candidates must be eligible to work in the United States. NRAO does not sponsor H-1B visas for this position. For qualified candidates who require visa sponsorship, NRAO may provide sponsorship through the J-1 Exchange Visitor Program, subject to applicable program requirements and eligibility. The Jansky Fellowship Program is open to early career applicants of any nationality who at the start of the fellowship will have not more than 5 years of postdoctoral experience, but well justified exceptions to this rule will be given full consideration. The applications will be evaluated relative to the opportunity and career stage, with preference given to the applicants within the first few years past their PhD award. Jansky Fellowships are awarded based upon a review by a committee that comprises distinguished scientists and astronomers from NRAO and external research institutes, the NRAO Assistant Director for Science Support and Research, and the Lead of the Jansky Fellowship program.

The nominal start of the fellowships is September 2027, but can begin at an earlier or later date (not later than January 2028).Application documents: All applications must include a cover letter, statement addressing selection criteria, curriculum vitae with publication list, summary of previous and current research, and a research proposal combined in a single PDF file. Please use the 'Add Resume' button to upload the entire application file, including the cover letter, in a pdf format. There is no need to upload your cover letter separately. Instructions on how to submit reference letters are provided at the end of this posting. All applications and reference letters must be submitted electronically. Cover letter: Please specify your proposed NSF NRAO/GBO location or non-resident host institution, and your second-choice location, which must be an NSF NRAO/GBO site (Socorro, Charlottesville, or Green Bank). If you are applying for a split fellowship as your first choice, please indicate both the NRAO location and host institution where you propose to spend your fellowship, and the proposed fraction of time at each location. Please note that if you don't provide a secondary choice for the fellowship appointment location, your application will be reviewed only for the single host of your choice. NSF NRAO is a Federally Funded Research and Development Center (FFRDC), and applications will not be accepted for non-resident fellowships at other FFRDCs. Statement addressing selection criteria: Please explicitly address the selection criteria. If you are applying for a non-resident or split fellowship appointment, it is especially important to describe how you, NRAO, and the host institution will benefit from your appointment as a Jansky Fellow. The statement must be maximum of two (2) pages, formatted with 12 pt. font size and at least 0.75in margins. Top tips for writing a good statement: Excellence of the research proposal and the candidate: Please summarize and highlight what makes your proposed research project strong and worth funding, and why you are the best person to deliver it. Leadership potential of the candidate and/or community service: Academic work goes beyond solely conducting research, and often includes community service (such as reviewing articles submitted for publication, serving on organizing committees for conferences) or leadership activities (such as leading projects or a scientific team, supervising students). If you have experience in either of these, please provide details here. If you don't have hands-on experience in these areas, but your proposed research includes for example a leadership aspect, briefly indicate what that would be and how you would approach it to successfully execute itSynergy between the proposed project and the chosen host: Explain why your chosen host location is the best place to carry out your proposed research. Mutual benefit of the fellowship project to NRAO and the applicant: As a Jansky Fellow you will have a unique opportunity to experience how working at an astronomical observatory looks like, and to contribute to its success. Jansky Fellows do not have any functional observatory duties assigned; however, their work or tools they develop during the fellowship period may advance NRAO facilities, data delivery or science. If your proposed research project incorporates novel techniques in data processing, visualization, big data handling, algorithms, computing, instrumentation etc, please indicate it here when addressing the mutual benefit criterion. Curriculum vitae: Provide a summary of your academic and employment history, and any relevant details pertaining to your academic career such as awards, observing programs, and relevant roles. Please include your full publication list in your CV. There is no page limit for the CV/publication list. Previous and current research: Provide a summary of your previous and current research. The summary must be a maximum of two (2) pages including figures and references, formatted with 12 pt font size and at least 0.75in margins. Research proposal: Your research proposal should address why having a Jansky Fellowship, and therefore a strong linkage to NRAO scientists and facilities, is important for achieving your research goals, and the development of your professional skills.
