Pacific Northwest National Laboratory (PNNL) has opened applications for the 2027 Linus Pauling Distinguished Postdoctoral Fellowship, a highly competitive research appointment for recent and upcoming PhD graduates in science and engineering. Fellows design an original research programme rather than joining only to execute a pre-defined project.
The published salary is $118,000 per year. Applications close on 15 October 2026 at 4:00 p.m. Pacific Time, and the fellowship is expected to begin in fall 2027.

What Makes the Pauling Fellowship Different
The central feature of the fellowship is intellectual ownership. Applicants are expected to propose a major research and development programme of their own design and explain why PNNL is the right place to execute it.
This means the application is closer to a research-proposal competition than a standard postdoctoral job application. A candidate must show scientific originality, feasibility, national-laboratory relevance and a credible path to high-impact results.
The Four Broad Research Categories
Applicants are asked to identify which PNNL area best fits their proposed programme:
- Scientific Discovery
- Sustainable Energy
- National Security
- Data Science & Computing
The project can be interdisciplinary, but the application needs a clear centre of gravity. A strong proposal should show how the research contributes to a PNNL mission area rather than using the laboratory merely as a prestigious host.
Examples of Research That Could Fit
PNNL works across a broad scientific landscape. Depending on the category, competitive proposals could involve areas such as advanced materials, catalysis, energy storage, grid resilience, climate and Earth systems, biological science, chemistry, quantum information, high-performance computing, cybersecurity, artificial intelligence, national-security science or data-intensive discovery.
The exact research topic is not prescribed. That flexibility is a major advantage for applicants with an ambitious project that sits between conventional departmental boundaries.
Who Can Apply?
The 2027 position requires candidates to have received a PhD in 2024 or later, or to complete the PhD by 31 August 2027, from an accredited college or university.
The doctorate must be in a science or engineering field connected to PNNL’s mission areas. The programme is aimed at researchers at the beginning of their postdoctoral career rather than established senior scientists.
Work Authorization
All PNNL staff must be able to demonstrate the legal right to work in the United States.
International researchers should read the eligibility and federal-credential sections carefully. PNNL’s current vacancy notes that foreign nationals who have not resided in the United States for three consecutive years may need a Local Site Specific Only federal risk determination rather than immediate eligibility for the standard PIV credential.
The posting also includes Department of Energy restrictions concerning certain affiliations with governments designated as countries of risk. Applicants affected by those rules may have additional disclosure and approval requirements.
The Research Proposal Is the Core of the Application
The application requires a detailed research proposal explaining the intended R&D programme, why it is novel, what impact it could have and why PNNL offers a distinctive environment for carrying it out.
A strong proposal should answer several questions:
- What specific scientific or engineering problem will you solve?
- Why is the problem important now?
- What is technically new about your approach?
- What evidence suggests the approach is feasible?
- Which PNNL capabilities make the laboratory especially suitable?
- What results could be achieved during the fellowship?
- How could the work open a larger research direction?
You Must Connect the Proposal to Recent PNNL Research
PNNL asks applicants to cite three publications from PNNL authors published within the last five years that most closely connect to the proposed research or demonstrate relevant PNNL expertise or facilities.
This is an important signal about how applications will be read. A generic research proposal with “PNNL” inserted at the end is unlikely to be persuasive. Applicants should identify real researchers, facilities, methods or programmes that create a clear advantage for their project.
How to Research Your PNNL Fit
Start with recent PNNL publications in your field. Then identify the researchers, directorates, user facilities or computational resources connected to those papers.
Look for complementary strengths rather than exact duplication. The best case is often that your expertise fills a gap while PNNL provides capabilities you could not easily access elsewhere.
Required Application Packet
PNNL requires the main application documents to be combined into a single PDF under the Additional Documents section.
The packet includes:
- A cover letter identifying the relevant research category.
- A current CV.
- An ORCID link if available.
- A detailed research proposal.
- The required discussion of recent PNNL publications and institutional fit.
Applicants should check the live careers posting before submission in case additional fields or system questions are required.
How to Write the Cover Letter
The cover letter should not repeat the entire research proposal. Use it to establish your research identity, identify the category that best fits your project and explain why your trajectory makes you ready to lead an independent programme.
Strong evidence may include first-author publications, a method or instrument you developed, a dataset you created, an interdisciplinary collaboration you led or a research problem where you made a clear intellectual contribution.
How to Make the Research Proposal Competitive
Originality alone is not enough. The proposal should be ambitious but technically grounded. State the central hypothesis or engineering objective clearly, break the programme into major research aims and explain the methods and outputs expected from each stage.
It is useful to distinguish between:
- The scientific question.
- The technical method.
- The PNNL capability you will use.
- The expected research output.
- The broader impact if the work succeeds.
A proposal that makes these relationships obvious is easier to evaluate than one built around broad language about innovation.
Why PNNL Fit Matters
PNNL is a U.S. Department of Energy national laboratory with major capabilities across energy, environment, national security and computational science. The fellowship is intended to place independent early-career researchers in that environment so they can use facilities and expertise that may not exist in a traditional university department.
Applicants should therefore explain why the work needs a national-laboratory setting rather than treating PNNL as interchangeable with any postdoctoral host.
Potential Work Locations
The vacancy lists multiple U.S. locations, including Richland and Sequim in Washington, College Park in Maryland, Seattle, and Portland. PNNL notes that it prefers Pauling Fellows to work at an appropriate PNNL site based on the nature of the proposed research.
Whether an appointment can be virtual or hybrid is determined by PNNL management. Applicants should not assume that a remote arrangement will be available.
Benefits
The current vacancy lists a broad employee-benefits package that may include medical, dental and vision insurance, retirement benefits, paid time off, life and disability insurance, employee assistance resources, relocation support and other programmes depending on eligibility.
Because some benefits can differ by appointment category, candidates should review the final offer and current PNNL policy rather than assuming every standard staff benefit applies identically.
Federal Credentialing Requirements
PNNL employees may be required to obtain and maintain a federal Personal Identity Verification credential. Background-investigation requirements depend on job duties and the relevant national-security or public-trust level.
This is a normal but important part of employment at a U.S. national laboratory. Applicants should answer eligibility and security questions accurately.
Who Is a Strong Candidate?
The strongest applicants are likely to have:
- A recent or near-complete PhD.
- A clear record of original scientific contribution.
- A research idea that is genuinely their own.
- A proposal that fits PNNL capabilities.
- Evidence of independence and leadership potential.
- Strong technical writing.
- A project ambitious enough to define a future research programme.
How to Apply
Applications are submitted through the official PNNL careers system for Job 11983. Prepare the required single-PDF application packet and complete the online application before the deadline.
The closing time is 15 October 2026 at 4:00 p.m. Pacific Time.
