We need to output HTML fragment with sections: Overview? The instruction: use for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). Do NOT repeat the job title as a heading. Include a section ONLY when posting has real, specific content for it. Remove boilerplate etc.
We need to parse the posting: It has Overview (some description about PNNL directorates). Then Responsibilities (detailed list). Then Qualifications (minimum and preferred). Then Hazardous Working Conditions/Environment Not Applicable (skip). Additional Information (security clearance etc). Then About PNNL (benefits etc). Then Commitment to Excellence and EEO (skip). Drug Free Workplace (skip). Security, Credentialing, And Eligibility Requirements (skip). Mandatory Requirements (skip). Rockstar Rewards (benefits details). Notice to Applicants (pay range info). Also there is mention of hybrid work arrangement (Schedule? maybe schedule). Also mention of pay: "PNNL lists the full pay range for the position in the job posting. Starting pay is calculated from the minimum of the pay range..." but no actual numbers given. So we cannot create Pay section because no specific numbers. The instruction: never create Pay/Schedule/Benefits sections unless posting actually states them. Benefits: there is mention of benefits in About PNNL: "excellent benefits including health insurance, and flexible work schedules." Also Rockstar Rewards lists many benefits. So we have benefits content. So we can include Benefits section with that content.
Schedule: mention hybrid work arrangement, regular on-site work. That's schedule info. So we can include Schedule section.
Pay: no specific numbers, so we should not include Pay section.
Overview: we could include an Overview section? The instruction says use headings like About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. Overview not in list but could be considered "About the role"? Might be better to use "About the role" heading for overview. But they said do NOT repeat the job title as a heading. Overview is not job title. Could use "About the role". However they gave examples of headings; we can use those. So we will have sections: About the role (overview), Responsibilities, Qualifications (maybe combine Minimum and Preferred), Benefits, Schedule. Also maybe Requirements? The posting has "Qualifications" but not separate Requirements. Could treat Qualifications as Requirements? But they listed Requirements as a possible heading. We'll use Qualifications heading for the qualifications content. Also maybe Skills? Could embed skills within qualifications. We'll not create Skills unless distinct.
We need to preserve all substantive information, not invent or summarize away detail. Must not omit details. So we need to include all details from overview, responsibilities, qualifications, benefits, schedule, etc. Also need to include security clearance info? That's part of Additional Information. Should we include that? It's substantive. Where to place? Could be under Requirements or Qualifications? It's about eligibility. Could be a separate section like "Requirements" maybe. The instruction: Use headings from list; we can use Requirements for eligibility/clearance etc. But we also have Qualifications. Might be better to have Requirements for eligibility (citizenship, clearance, drug testing) and Qualifications for education/experience. Let's see: The posting has "Minimum Qualifications:" and "Preferred Qualifications:" plus Additional Information about security clearance, citizenship, drug testing, etc. Also "Hazardous Working Conditions/Environment Not Applicable" (skip). So we can have Requirements section for eligibility (citizenship, clearance, drug testing). Qualifications section for education/experience and preferred qualifications.
We also have About PNNL paragraph about benefits and location etc. That could go under Benefits or About the role? Benefits section should contain benefits details. The About PNNL also mentions location, campus, etc. That could be part of About the role? Might be better to have About the role include overview of PNNL and directorates, mission, etc. Then Benefits section separate.
Schedule: hybrid work arrangement.
We must not include boilerplate like EEO, drug free workplace, etc. Remove those.
We must not include navigation, cookie, legal, etc.
We must not include duplicated lines.
We must output only HTML fragment.
Let's extract substantive content:
Overview (About the role):
- At PNNL, core capabilities divided among major departments called Directorates: National Security, Earth and Biological Sciences, Physical and Computational Sciences, Energy and Environment.
- Plus Environmental Molecular Sciences Laboratory, a DOE Office of Science user facility on PNNL campus.
- National Security Directorate (NSD) drives science-based mission-focused solutions to complex real-world threats.

So we need to include all details from overview, responsibilities, qualifications, benefits, schedule, etc. Also need to include security clearance info? That's part of Additional Information. Should we include that? It's substantive. Where to place? Could be under Requirements or Qualifications? It's about eligibility. Could be a separate section like "Requirements" maybe.

Make sure to preserve all details. Let's craft text precisely. Overview text: combine into maybe two paragraphs. Paragraph 1: At PNNL, core capabilities divided among major departments called Directorates: National Security, Earth and Biological Sciences, Physical and Computational Sciences, Energy and Environment. Plus Environmental Molecular Sciences Laboratory, a DOE Office of Science user facility on PNNL campus. Paragraph 2: National Security Directorate drives science-based mission-focused solutions to complex real-world threats.

Focus on discovering signatures and understanding threats by creating materials, methods, technologies to detect and analyze them. Researchers deliver solutions for addressing complex mission challenges: explosives detection, biological threat detection, chemical and nuclear forensics, special nuclear materials. Now Responsibilities list items as given. We need to exclude the hybrid work arrangement sentence from responsibilities; we will put it in Schedule. So responsibilities list excludes that sentence. Let's list responsibilities: - Model PWR core physics and TPBAR performance using neutron transport, diffusion, depletion, and fuel-cycle methods. - Analyze TPBAR effects on reactivity, power distribution, neutron flux, and tritium production. - Develop, run, and evaluate simulations using established reactor physics codes. - Automate analyses and process results
