About the Role
Overview

At PNNL, our core capabilities are divided among major departments that we refer to as Directorates within the Lab, focused on a specific area of scientific research or other function, with its own leadership team and dedicated budget.  

 

Our Science & Technology directorates include National Security, Earth and Biological Sciences, Physical and Computational Sciences, and Energy and Environment. In addition, we have an Environmental Molecular Sciences Laboratory, a Department of Energy, Office of Science user facility housed on the PNNL campus. 

 

The Physical and Computational Sciences Directorate's (PCSD’s) strengths in experimental, computational, and theoretical chemistry and materials science, together with our advanced computing, applied mathematics and data science capabilities, are central to the discovery mission we embrace at PNNL. But our most important resource is our people—experts across the range of scientific disciplines who team together to take on the biggest scientific challenges of our time.  

 

The Physical Sciences Division stewards discovery science research portfolios including catalysis, materials science, separations, analytical chemistry, geosciences, and chemical physics. Our research strives to refine our molecular-level understanding of multiphase systems and phenomena including complex interfaces. We discover and apply new knowledge to address major national priorities and needs in energy sustainability through the development of new energy storage technologies and the creation of high-value fuels and materials from abundant wastes. 

 

This part time internship will be approximately 20 hours per week.


Responsibilities

We are seeking a part time PhD Intern researcher in theoretical and computational chemical physics to join the Chemical Physics Theory Group in the Physical and Computational Sciences Directorate at Pacific Northwest National Laboratory (PNNL).

 

The research focuses on developing relativistic theoretical methods to model electron dynamics in hyperfine couplings, electric-field gradients, and L- or M-edge X-ray spectroscopies. This work combines relativistic electronic structure theory, many-body physics, and machine learning approaches.

 

This theory position is based at Pacific Northwest National Laboratory (PNNL) in Richland, Washington and involves multi-institutional collaborations.

 

What you will do:

  • Develop relativistic theoretical methods and downfolding protocols for model systems and core spectroscopies
  • Conduct research and collaborate with team members in a multi-institution research team
  • Lead manuscript preparation and maintain a strong publication record in the peer-reviewed scientific literature
  • Present research at technical conferences and project or program review meetings
  • Communicate and collaborate with researchers across the multi-institution project team
  • Participate in the development of research proposals as needed

Qualifications

Minimum Qualifications:

  • Candidates must be currently enrolled/matriculated in a PhD program at an accredited college. 
  • Minimum GPA of 3.0 is required.

Preferred Qualifications:

  • Experience in ground- and excited-state relativistic electronic structure methods, and many-body physics

  • Experience with scientific programming and code development

  • Programming experience in Fortran, C++, and/or Python

  • Experience with four component relativistic quantum chemistry methods

  • Strong written and verbal communication skills

  • Experience working in collaborative and interdisciplinary research environments

About PNNL

Pacific Northwest National Laboratory (PNNL) is a world-class research institution powered by a highly educated, diverse workforce committed to the values of Integrity, Creativity, Collaboration, Impact, and Courage. Every year, scores of dynamic, driven people come to PNNL to work with renowned researchers on meaningful science, innovations and outcomes for the U.S. Department of Energy and other sponsors; here is your chance to be one of them!
 

At PNNL, you will find an exciting research environment and excellent benefits including health insurance, and flexible work schedules. PNNL is located in eastern Washington State—the dry side of Washington known for its stellar outdoor recreation and affordable cost of living. The Lab’s campus is only a 45-minute flight (or ~3 hour drive) from Seattle or Portland, and is serviced by the convenient PSC airport, connected to 8 major hubs.


Commitment to Excellence and Equal Employment Opportunity

Our laboratory is committed to fostering a work environment where all individuals are treated with fairness and respect while solving critical challenges in fundamental sciences, national security, and energy resiliency. We are an Equal Employment Opportunity employer.

 

Pacific Northwest National Laboratory (PNNL) is an Equal Opportunity Employer. PNNL considers all applicants for employment without regard to race, religion, color, sex, national origin, age, disability, genetic information (including family medical history), protected veteran status, and any other status or characteristic protected by federal, state, and/or local laws.

 

We are committed to providing reasonable accommodations for individuals with disabilities and disabled veterans in our job application procedures and in employment. If you need assistance or an accommodation due to a disability, contact us at careers@pnnl.gov.


Drug Free Workplace

PNNL is committed to a drug-free workplace supported by Workplace Substance Abuse Program (WSAP) and complies with federal laws prohibiting the possession and use of illegal drugs.


Security, Credentialing, and Eligibility Requirements

As a national laboratory, PNNL is responsible for adhering to the Homeland Security Presidential Directive 12 (HSPD-12) and Department of Energy (DOE) Order 473.1A, which require new employees to obtain and maintain a HSPD-12 Personal Identify Verification (PIV) Credential. To obtain this credential, new employees must successfully complete the applicable tier of federal background investigation post hire and receive a favorable federal adjudication.  The tier of federal background investigation will be determined by job duties and national security or public trust responsibilities associated with the job. All tiers of investigation include a declaration of illegal drug activities, including use, supply, possession, or manufacture within the last 1 to 7 years (depending on the applicable tier of investigation). Illegal drug activities include 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) Federal risk determination to maintain employment. Once you meet the three-year residency requirement thereafter, you will be required to obtain a PIV credential to maintain employment. The tier of federal background investigation required to obtain the PIV credential will be determined by job duties at the time you become eligible for the PIV credential.


Mandatory Requirements

Please be aware that the Department of Energy (DOE) prohibits DOE employees and contractors from having any affiliation with the foreign government of a country DOE has identified as a “country of risk” without explicit approval by DOE and Battelle. If you are offered a position at PNNL and currently have any affiliation with the government of one of these countries, you will be required to disclose this information and recuse yourself of that affiliation or receive approval from DOE and Battelle prior to your first day of employment.


Rockstar Rewards

Regular Hourly:

Employees are offered an employee assistance program and business travel insurance. Employees are eligible for the company funded pension plan and 401k savings plan, once eligibility requirements are met.

 

Temporary Hourly:

Employees are offered an employee assistance program and business travel insurance.
