Postdoctoral Research Associate, MPEX Boundary and PMI Modeling

We need to output HTML fragment with sections: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. Only include sections with real specific content. We must not repeat job title. Must not include Job ID/requisition numbers as headings; can fold into short p or drop. Remove boilerplate like EEO, legal, etc. Must preserve all substantive info. We need to parse the posting. Key sections: Overview: description of role: "We are seeking a Computational Physicist to carry out modeling of plasma transport and plasma-material interactions (PMI) in the Materials Plasma Exposure eXperiment (MPEX), a high-flux superconducting linear plasma facility nearing completion at ORNL. The candidate will utilize state-of-the-art 3D plasma boundary simulation tools as part of the MPEX Whole-Device Model, working closely with the experimental team to understand this device’s PMI physics and optimize performance of the device in its upcoming campaigns. The position resides in the Power Exhaust and Particle Control (PEPC) group of the Fusion Energy Division at Oak Ridge National Laboratory. The PEPC group performs experimental and modeling work, focused on the boundary region of tokamaks, stellarators, and linear devices, for present-day and future fusion facilities worldwide." That's about the role. Major Duties/Responsibilities: list of duties. Basic Qualifications: PhD in Plasma Physics, Electrical Engineering, Nuclear Engineering, or a closely related field completed within the last 5 years, or expect to complete a PhD by June 30th, 2027. Preferred Qualifications: list. Special Requirements: temporary 24-month position, appointment length up to 24 months with potential for extension, initial appointments and extensions subject to performance and availability of funding. For employment at ORNL, a Real ID compliant form of identification will be required. Additionally, ORNL is subject to DOE access restrictions. All employees must also be able to obtain and maintain a federal PIV card as mandated by HSPD-12 and 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. 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. About ORNL: description of ORNL, benefits list. Other info: position will remain open for a minimum of 5 days after which it will close when a qualified candidate is identified and/or hired. We accept file types... Resumes from third party vendors will not be accepted... If you have trouble applying... ORNL is an equal opportunity employer... UT-Battelle is an E-Verify employer. We need to remove boilerplate: EEO, legal, scam-warning, etc. Also remove navigation/cookie etc. The "About ORNL" includes benefits list; we can include Benefits section with that list. Pay and Schedule: not mentioned explicitly. There's no pay or schedule info. So we should NOT include Pay or Schedule sections. We need sections: About the role (maybe "About the role" heading), Responsibilities, Requirements (maybe Basic Qualifications), Qualifications (Preferred Qualifications), Skills (maybe programming languages etc), Benefits (ORNL benefits). Could also include "Special Requirements" maybe as part of Requirements or Qualifications? The instruction: Use headings for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). So we should map content to these headings. - About the role: overview description. - Responsibilities: Major Duties/Responsibilities list. - Requirements: Basic Qualifications (maybe also Special Requirements? but those are more like eligibility). Could include Special Requirements under Requirements as well. - Qualifications: Preferred Qualifications. - Skills: Programming experience etc. Could also include ability to work individually/team, communication skills. - Benefits: ORNL benefits list. We must not include headings with filler text. Ensure each section has substantive content. We need to output only HTML fragment, no /, no markdown fences. Let's craft. We'll have:

Requirements

• PhD in Plasma Physics, Electrical Engineering, Nuclear Engineering, or a closely related field completed within the last 5 years, or expect to complete a PhD by June 30th, 2027.
• Must be able to obtain and maintain a federal Personal Identity Verification (PIV) card, including successful completion of a Federal Tier 1 background check investigation (includes declaration of illegal drug activities within the past year).
• Must present a Real ID compliant form of identification for employment at ORNL.
• If not a U.S. resident for three consecutive years, must obtain a favorable Local Site Specific Only (LSSO) risk determination; after meeting the three‑year residency requirement, a PIV credential is required.
• Appointment is a temporary 24‑month position with potential for extension, subject to performance and funding availability.

But we need to preserve all substantive info; we should not lose details like "Special Requirements: This is a temporary 24-month position..." etc. So include those. We could combine basic qualifications and special requirements under Requirements.

Qualifications

• Experience with boundary and divertor plasma physics, and use of codes such as EMC3‑EIRENE, SOLPS, UEDGE, SOLEDGE, or similar.
• Experience with plasma‑material interactions, including models for sputtering, impurity transport, and sheath physics.
• Programming experience in Python, MATLAB, Fortran, C++ and other science‑relevant languages.
• Ability to work individually and/or as part of a team, set priorities to accomplish multiple tasks within deadlines, and adapt to ever‑changing needs.
• Excellent oral and written communication skills supporting regular interactions with fellow research staff, peer reviewers, research sponsors, and to prepare reports, proposals, and presentations.

But note that some of these are also skills; but we have Skills section separate. Could split: Qualifications = preferred qualifications (experience, etc). Skills = programming languages, teamwork, communication. Let's decide: - Qualifications: Preferred Qualifications (experience with boundary/divertor plasma physics, PMI models). - Skills: Programming experience, ability to work individually/team, communication skills. We'll include both. Now Benefits: list from About ORNL: medical and retirement plans, flexible work hours, on-site fitness, banking, cafeteria, Prescription Drug Plan, Dental Plan, Vision Plan, 401(k) Retirement Plan, Contributory Pension Plan, Life Insurance, Disability Benefits, Generous Vacation and Holidays, Parental Leave, Legal Insurance with Identity Theft Protection, Employee Assistance Plan, Flexible Spending Accounts, Health Savings Accounts, Wellness Programs, Educational Assistance, Relocation Assistance, Employee Discounts. We'll put as

. We must not include Pay or Schedule sections. Now ensure we didn't include boilerplate like EEO, equal opportunity, etc. We removed those lines. Check for any leftover: "ORNL is an equal opportunity employer..." removed. "UT-Battelle is an E-Verify employer." removed. "If you have trouble applying..." removed. "This position will remain open for a minimum of 5 days..." removed (that's application instruction). "We accept Word..." removed. "Resumes from third party vendors will not be accepted;" removed. Now ensure we preserved all substantive info: overview, duties, basic qualifications, preferred qualifications, programming experience, teamwork, communication, special requirements (temporary position, PIV, Real ID, residency), ORNL description and benefits. We included ORNL description? We included benefits but not the description about ORNL legacy etc. That's substantive; we could include a short paragraph under About the role or maybe a separate section? There's no heading for "About ORNL". Could incorporate into About the role or maybe a brief note. The instruction: Use headings for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). So we should not create other headings. We can include ORNL description in About the role paragraph or maybe in Benefits? Better to add a short paragraph after overview about ORNL legacy etc. It's substantive; we can include in About the role. Thus About the role paragraph will include overview plus ORNL description. Let's craft About the role:

We are seeking a Computational Physicist to carry out modeling of plasma transport and plasma‑material interactions (PMI) in the Materials Plasma Exposure eXperiment (MPEX), a high‑flux superconducting linear plasma facility nearing completion at ORNL. The candidate will utilize state‑of‑the‑art 3D plasma boundary simulation tools as part of the MPEX Whole‑Device Model, working closely with the experimental team to understand this device’s PMI physics and optimize performance of the device in its upcoming campaigns. The position resides in the Power Exhaust and Particle Control (PEPC) group of the Fusion Energy Division at Oak Ridge National Laboratory. The PEPC group performs experimental and modeling work focused on the boundary region of tokamaks, stellarators, and linear devices for present‑day and future fusion facilities worldwide. As a U.S. Department of Energy Office of Science national laboratory, ORNL has an 80‑year legacy of addressing the nation’s most pressing challenges, with over 7,000 dedicated individuals committed to scientific breakthroughs that translate into solutions for energy, environmental, and security challenges.

Now Responsibilities list: from Major Duties/Responsibilities. Let's list each bullet: - Perform interpretive three-dimensional boundary plasma simulations of MPEX, in order to inform and optimize radiofrequency (RF) power coupling, PMI target conditions, and overall device performance in preparation for early device operations. - Integrate boundary plasma simulations with impurity transport models to assess the production and transport of in-vessel impurities in MPEX operating scenarios. - Perform predictive modeling to inform the design of new MPEX target geometries, with a focus to improve access to divertor-relevant target exposure conditions. - Validate simulation results against experimental data and constrain code inputs to reduce uncertainty in predictions for future experiments and guide improvements to the physics model. - Work closely with teams of diagnosticians, theorists, applied mathematicians, and experimental plasma physicists. - Create high impact research results to report in peer-reviewed journals and present at scientific conferences. - Maintain commitment to the implementation and perpetuation of ORNL values and ethics. - Deliver ORNL’s mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service. - Promote equal opportunity by fostering a respectful workplace – in how we treat one another, work together, and measure success. Note: The last bullet about equal opportunity is borderline EEO; but it's part of responsibilities? It's about promoting equal opportunity. Might be considered boilerplate but it's part of the job description. The instruction: Remove cookie/navigation/legal/EEO/equal-opportunity/scam-warning boilerplate. This bullet is about promoting equal opportunity; could be considered EEO boilerplate. Safer to remove it. We'll remove that bullet. Now Requirements: include basic qualifications and special requirements. Let's list: - PhD in Plasma Physics, Electrical Engineering, Nuclear Engineering, or
