Mechanical Engineer I
for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). They said do NOT repeat the job title as a heading (the page already shows it) and do NOT put Job ID / requisition numbers as headings — fold minor metadata into a short
or drop it. Preserve ALL substantive information; do NOT invent or summarize away detail. Remove cookie/navigation/legal/EEO/equal-opportunity/scam-warning boilerplate, duplicated lines, and application instructions. IMPORTANT: include a section ONLY when the posting has real, specific content for it — never emit a heading followed by filler/placeholder text (e.g. "commensurate with experience", "not specified", "N/A", "varies", "TBD") and never create Pay/Schedule/Benefits sections unless the posting actually states them. Prefer a few substantive sections over many thin ones. We need to parse the posting: It includes About Us, About LJC, The Role We Want You For, The Specifics of the Role, Requirements, Some Things You Should Know, Why Clayco and LJC? (awards), Benefits, Compensation. We need to map to sections: About the role (maybe combine About Us and About LJC? Actually "About the role" is a heading they gave as example. Could use "About the role" for description of role. Could also have "Responsibilities" for specifics. "Requirements" for requirements. "Benefits" for benefits. "Pay" for compensation (they have compensation description). "Schedule" not present, so omit. We must not create sections with placeholder text. So we need to ensure each section has substantive content. We need to output only HTML fragment, no /, no markdown fences. Thus produce something like:
About the role
... description ...
Responsibilities
- ... ...
Requirements
- ... ...
Benefits
- ... ...
Pay
... compensation description ...
We need to preserve all substantive information. Let's extract.

Compensation: - The salary range for this position considers a wide range of factors in making compensation decisions including but not limited to: Education, qualifications, skills, training, experience, certifications, internal equity, and location. Compensation decisions are dependent on the facts and circumstances of each case. We need to decide sections: About the role (maybe combine About Us and About LJC and The Role We Want You For? Actually "About the role" could be description of role: The Entry-Level Mechanical Engineer will support... etc. Could also include some about company? But they said "About the role" is an example heading. We'll use that for the role description (The Role We Want You For plus maybe The Specifics of the Role? Actually specifics are responsibilities). So we can put role overview in About the role, then Responsibilities separate. Thus:About the role

for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule)." It says e.g., meaning those are examples, not exclusive. But they also say "Prefer a few substantive sections over many thin ones." So we could add a section "About the company" if we have substantive content. However they said "include a section ONLY when the posting has real, specific content for it — never emit a heading followed by filler/placeholder text". So we could add About the company with the About Us and About LJC paragraphs. That seems substantive. But they also said "Do NOT repeat the job title as a heading (the page already shows it) and do NOT put Job ID / requisition numbers as headings — fold minor metadata into a short
or drop it." So we can add About the company. Thus sections: About the company, About the role, Responsibilities, Requirements, Benefits, Pay. We need to ensure we don't create Qualifications, Skills sections unless we have content. We have Requirements which covers qualifications and skills. Could also split but better to keep as Requirements. Now Benefits: we have bullet points. Pay: we have compensation description. Now we need to ensure we preserve all substantive information. Did we miss any? The "Some Things You Should Know" and "Why Clayco and LJC?" we haven't included. Could incorporate into About the company section as additional paragraphs. Thus About the company paragraph(s) will include: - Clayco description. - LJC description. - Some Things You Should Know (collaborative design-build approach, creative complex award-winning high-profile jobs, fast pace). - Why Clayco and LJC? (awards list). We'll combine into a few paragraphs. Now ensure we don't include any boilerplate like EEO etc. Not present. Now output HTML fragment. Let's craft. We need to wrap each section in
