We need to output HTML fragment with sections: About the role? Actually the posting includes "About Radiant" description, then "Responsibilities", "Qualifications", "Desired Qualifications", "Benefits And Perks", "Total Compensation And Benefits". Also there is a compensation range at end. Need to follow rules: Use for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). We should map headings accordingly. The posting has sections: About Radiant (company description) - could be "About the role"? Actually "About Radiant" is company overview. Could be "About the role"? The instruction says use headings like About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. We should include sections only when posting has real specific content. So we can have:
- About the role? The posting includes "Radiant is seeking a highly motivated Nuclear Engineer to join the team." That's about the role. Could combine with company description? Probably "About the role" heading with description of role and company? But we have separate "About Radiant" which is company overview. The instruction says use headings like About the role, Responsibilities, etc. We can create "About the role" containing the description of the role and maybe company overview? However we must not repeat job title as heading. We can include a short paragraph about the role and company.
Better: Use "About the role" for the paragraph describing the role and company. Then "Responsibilities" for bullet list. Then "Qualifications" for required qualifications. Then maybe "Desired Qualifications" could be under "Skills" or separate? The instruction says we can have Skills section. Could combine desired qualifications under Skills. But we should not create thin sections. Perhaps we can have "Qualifications" covering both required and desired? But we need to preserve all substantive info. Could have "Qualifications" for required, and "Skills" for desired. That seems okay.
Then "Benefits" for benefits and perks. Then "Pay" for compensation range. Also maybe "Schedule"? Not present, so omit.
We must not include boilerplate like EEO, export controls, application instructions, etc. Remove those. Also remove "Total Compensation And Benefits" heading? We'll incorporate into Benefits and Pay sections.
We must preserve all substantive info: company description, responsibilities list, qualifications list, desired qualifications list, benefits list, compensation range.
Let's extract:
About Radiant: "Radiant is an El Segundo, CA-based startup building the world’s first mass-produced, portable nuclear microreactors. The company’s first reactor, Kaleidos, is a 1-megawatt, fail-safe microreactor that can be transported anywhere power is needed and run for up to 5 years without refueling. Portable nuclear power with rapid-deploy capability can replace similar-sized diesel generators and provide critical asset support for hospitals, data centers, remote sites, and military bases. Radiant’s unique, practical approach to nuclear development leverages modern software engineering to rapidly deliver safe, factory-built microreactors that use existing, well-qualified materials. Founded in 2020, Radiant is on track to test its first reactor at the Idaho National Laboratory this summer, with initial customer deliveries beginning in 2028."

About the role
Radiant is an El Segundo, CA-based startup building the world’s first mass-produced, portable nuclear microreactors. The company’s first reactor, Kaleidos, is a 1‑megawatt, fail-safe microreactor that can be transported anywhere power is needed and run for up to 5 years without refueling. Portable nuclear power with rapid‑deploy capability can replace similar‑sized diesel generators and provide critical asset support for hospitals, data centers, remote sites, and military bases. Radiant’s unique, practical approach to nuclear development leverages modern software engineering to rapidly deliver safe, factory‑built microreactors that use existing, well‑qualified materials. Founded in 2020, Radiant is on track to test its first reactor at the Idaho National Laboratory this summer, with initial customer deliveries beginning in 2028. Radiant is seeking a highly motivated Nuclear Engineer to join the team.

Pay
Compensation range: $105K - $130K
We might also include a paragraph about total compensation philosophy? The instruction says include a section only when posting has real specific content. The total compensation paragraph is somewhat generic but still substantive. Could add under Pay or Benefits? But we already have Pay section with range. The paragraph about compensation philosophy could be included under Pay as additional prose. However we must not invent or summarize away detail. We can add aunder Pay before the range: "Radiant compensates people for impact and invests in those who continue to raise the bar. Radiant’s new hire compensation package includes base salary, substantial equity grants, and comprehensive health benefits. Total compensation and level are determined through a rigorous evaluation of interview performance, experience, education, and qualifications, and are designed to support continued growth as scope, responsibility, and impact expand at Radiant. The best of today’s advanced reactor builders don’t wait for job postings. They join the winning team." That is substantive. So we will include that paragraph in Pay section before the range. Thus final HTML. Check no extra headings like Requirements etc
