for prose. Do NOT repeat job title as heading. Do NOT put Job ID / requisition numbers as headings — fold minor metadata into a short
or drop it. Remove boilerplate, duplicated lines, application instructions. Include a section ONLY when posting has real, specific content for it — never emit heading followed by filler/placeholder text. Prefer few substantive sections over many thin ones.
We need to preserve all substantive information. Let's extract content.
Job Summary paragraph: "In this role, you will conduct field investigations and client interviews to determine work scope and cost estimates for a project's mechanical aspects. You will lead design, development, modification, and evaluation of mechanical components and processes.

Pay Rate: "$59.35–$77.03 / Hour (USD)". Should be in Pay section if present. We need a Pay section only if posting actually states them. Yes, we have pay rate. So we need a Pay section with that info.
Schedule: Onsite Flexibility: Hybrid — at least 3 days per week in-person at the assigned office or project. Also mention weekly in-person schedules determined etc. So we have schedule info. So we need a Schedule section.
We also have Contract Details: Position Type: Contract, Contract Duration: 12 months, Work Authorization: Applicants must be authorized to work for ANY employer in the U.S. We are unable to sponsor or take over sponsorship of an employment Visa at this time. This is metadata; we can fold into a short
maybe under a generic "Contract Details" section? But we should avoid creating many thin sections. Perhaps combine Contract Details into a short paragraph under a section like "Contract Information". However the instruction: "Prefer a few substantive sections over many thin ones." So maybe we can incorporate contract details into a short paragraph under a section like "Position Details". But we need headings only for sections with real content. Could we have a section "Contract Details" with a
containing those details? That's okay if it's substantive. It's not just filler. It includes position type, duration, work auth. That's substantive.
But we also have Pay and Schedule sections separate.
We also have About the Client and About GTT sections.
We also have Job Summary maybe as "About the role". The instruction: use
for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). So we can use those headings.
Thus sections: About the role (Job Summary), Responsibilities (Key Responsibilities), Skills (Required Skills), Qualifications (Education Requirements + Required Experience maybe combine?), Benefits, Pay, Schedule, About the Client, About GTT. Possibly also Contract Details? Could combine with About the role? Might be better to have a short "Contract Details" paragraph under About the role? But we need to preserve all substantive info. Could add a
after About the role heading that includes contract details. However the instruction: "Use
for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule)." It doesn't forbid other headings, but suggests those as examples. We could add a heading "Contract Details" if we want, but better to keep few sections. Maybe we can incorporate contract details into About the role paragraph.
Let's craft About the role paragraph: combine job summary + contract details (position type, duration, work auth). Also mention location? Location: Houston, TX (Preferred) or Chandler, AZ. Onsite Flexibility: Hybrid — at least 3 days per week in-person at the assigned office or project. That's schedule info; we will put in Schedule section.
Thus About the role paragraph: "This is a 12-month contract position requiring authorization to work for any U.S. employer (no visa sponsorship). In this role, you will conduct field investigations and client interviews to determine work scope and cost estimates for a project's mechanical aspects. You will lead design, development, modification, and evaluation of mechanical components and processes.
