Major Duties/Responsibilities

The position requires collaboration within a multi-disciplinary research environment consisting of mathematicians, computational and computer scientists, and domain scientists conducting basic and applied research in support of ORNL's mission.

Specific Responsibilities Include

Participation in the development and analysis of new computational methodologies for scientific problems, often customized to complex and large-scale scientific applications
Delivery and support of mathematical technologies for various scientific disciplines and applications
Dissemination of research through peer-reviewed papers and technical reports, as well as seminar and conference presentations
Active participation in professional organizations

Basic Qualifications

A PhD in Mathematics, Applied Mathematics, Computational Science, or a related field completed within the last 5 years

Preferred Qualifications

Experience in one more of the following areas:
Mathematical tools for data analysis
Numerical methods for differential and integral equations
Modern machine learning software tools and frameworks
Implementation of scalable numerical algorithms on HPC architectures
Excellent written and verbal communication and interpersonal skills.
The ability to obtain and maintain a DOE Security Clearance
Special Requirements

Applicants cannot have received their Ph.
D.

more than five years prior to the date of application and must complete all degree requirements before starting their appointment.

All employees must also be able to obtain and maintain a federal Personal Identity Verification (PIV) card as mandated by Homeland Security Presidential Directive 12 (HSPD-12) and Department of Energy (DOE) Order 473.1A, which requires a favorable post-employment background investigation.

To obtain this credential, new employees must successfully complete and pass a Federal Tier 1 background check investigation. This investigation includes a declaration of illegal drug activities, including use, supply, possession, or manufacture within the last year. This includes marijuana and cannabis derivatives, which are still considered illegal under federal law, regardless of state laws.

For Foreign National Candidates

If you have not resided in the U.S.

for three consecutive years, you are not eligible for the PIV credential and instead will need to obtain a favorable Local Site Specific Only (LSSO) risk determination to maintain employment.

Once you meet the three-year residency requirement, you will be required to obtain a PIV credential to maintain employment.

Instructions To Apply

Please submit a cover letter, curriculum vitae, research statement, and three letters of reference when applying to this position.

You may upload these documents directly to your application or have them sent to with the position title and number referenced in the subject line.

For full consideration, please submit materials by November 1, 2025.
