Heavy Duty Diesel Mechanic

We need to output HTML fragment with sections: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. Only include sections if posting has real specific content. We must not repeat job title. Must not include Job ID etc. Must remove boilerplate (EEO, legal, etc). Must preserve all substantive info. We need to parse the posting. Let's extract sections: Intro: "Be part of a group that is safety driven and values inclusion, where care, courage and curiosity guide how we work and how we treat each other." This is values, maybe part of About the role? But we have "About The Role" heading later. Then "Balanced Work-Life Rhythm with a family‑friendly rotating roster of 5 on / 5 off / 4 on, working 12‑hour day and night shifts, giving you more time for what matters most." This is schedule info. "Permanent employment with a leading global company, offering competitive pay, tool allowance, and a comprehensive benefits package designed to make life better for you and your loved ones." This is pay and benefits. "We’re Finding Better Ways™ to provide the materials the world needs, now and in the future. Our values – care, courage and curiosity – guide how we work and how we treat each other. We are committed to building a diverse and inclusive workforce. Women are strongly encouraged to apply. All qualified applicants will be considered for employment without regard to gender or any other protected characteristic. Hiring decisions are based on merit, qualifications, and business needs." This is EEO boilerplate; we should remove. Then "About The Role" heading. Then description: "We are looking for a Mobile Equipment Mechanical Maintainer to join our Mobile Maintenance team at Kennecott Copper, supporting the safe and reliable operation of our large mobile mining fleet. This is a great opportunity for an experienced and safety‑focused tradesperson to apply their skills in a dynamic operational environment, working a rotating 5 on / 5 off / 4 on roster (12‑hour days and nights). Reporting to the Supervisor – Mobile Maintenance and working in a collaborative and safety‑driven team within Asset Management, you will be" Then list of duties: bullet points (actually sentences separated by line breaks). Let's capture: - Performing preventative and corrective maintenance on large-scale mobile mining equipment - Diagnosing mechanical, hydraulic, and electrical faults and implementing safe, effective solutions - Maintaining haul trucks, water trucks, and auxiliary equipment including dozers, graders, and excavators - Using tools, equipment, and diagnostic systems safely and efficiently - Following all safety, environmental, and company procedures and standards - Contributing to continuous improvement through proactive identification of equipment and process improvements Then "About You" heading. Then bullet list: - A commitment to the safety of yourself and your team - Minimum 3 years’ experience working with heavy‑duty diesel mechanical systems, including hydraulics and electrical fundamentals - Willingness and ability to work rotating 12‑hour day and night shifts - Confidence in reading and interpreting technical manuals, schematics, and standard work procedures - Familiarity with diagnostic software for Cummins, Komatsu, and Caterpillar systems (highly desirable) - A collaborative mindset with respect for others in a team‑oriented and inclusive environment Then "What we offer" heading. Then bullet list: - A safety-focused and inclusive working environment - Access to top-tier family-friendly health programs including medical, prescription drug, dental, vision, life insurance coverage, and various voluntary benefits. - 401(k) matching program (company matched .50 per dollar up to 6% of your base pay) - Generous Rio Tinto employee share program, which allows you to purchase Rio Tinto Company shares. - Comprehensive leave policies which cover all moments that matter in life PTO (paid time off), paid holidays, and paid bereavement leave. - A favorable child-caregiver leave program (Up to 100% salary top-up) - Ongoing Employee Assistance Program (EAP) for you and your family; to help in addressing educational opportunities, addiction treatment, depression, stress, domestic issues, financial management, and legal concerns. - Discount programs for leisure purposes and access to Virgin Pulse with incentives supporting your wellbeing. Then "Where You’ll Be Working" heading with description of Kennecott mine. Then "About Rio Tinto" heading with company description. Then "Respect and Inclusion" heading with EEO again; we should remove. We need to decide which sections to include: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. We have content for: - About the role: we have the paragraph after "About The Role" describing role and roster. Could be used. - Responsibilities: the list of duties under "About The Role" after "you will be". That's responsibilities. - Requirements: maybe the "About You" bullet list includes experience, willingness to work shifts, etc. Could be requirements. - Qualifications: maybe similar to requirements; but we could combine? The instruction says prefer few substantive sections over many thin ones. We could include About the role, Responsibilities, Requirements, Benefits, Schedule. Pay maybe mentioned: "competitive pay, tool allowance". That's specific enough for Pay section. Schedule: we have rotating roster details. We need to avoid filler like "commensurate with experience". Not present. We must not include sections with placeholder text. Thus we can output:

About the role

We are looking for a Mobile Equipment Mechanical Maintainer to join our Mobile Maintenance team at Kennecott Copper, supporting the safe and reliable operation of our large mobile mining fleet. This is a great opportunity for an experienced and safety‑focused tradesperson to apply their skills in a dynamic operational environment, working a rotating 5 on / 5 off / 4 on roster (12‑hour days and nights). Reporting to the Supervisor – Mobile Maintenance and working in a collaborative and safety‑driven team within Asset Management, you will be ...

but we need to preserve the duties list separately under Responsibilities. Better: About the role paragraph could be the introductory sentences before the list. Let's extract: "We are looking for a Mobile Equipment Mechanical Maintainer to join our Mobile Maintenance team at Kennecott Copper, supporting the safe and reliable operation of our large mobile mining fleet. This is a great opportunity for an experienced and safety‑focused tradesperson to apply their skills in a dynamic operational environment, working a rotating 5 on / 5 off / 4 on roster (12‑hour days and nights). Reporting to the Supervisor – Mobile Maintenance and working in a collaborative and safety‑driven team within Asset Management, you will be" We could end with "you will be" and then responsibilities list. Thus About the role paragraph ends before list. Responsibilities: list of duties. Requirements: maybe combine experience, shift willingness, etc. Could be "About You" bullet list. Qualifications: maybe not needed if we have Requirements. Skills: maybe include familiarity with diagnostic software etc. But we could incorporate into Requirements. Better to have sections: About the role, Responsibilities, Requirements, Benefits, Schedule, Pay. Pay: we have "competitive pay, tool allowance". Also mention 401(k) matching, employee share program etc. Those are benefits. Pay could be just "competitive pay, tool allowance". But we also have benefits details. We could make Benefits section include health programs, 401(k), share program, leave policies, child-caregiver, EAP, discount programs, Virgin Pulse. Schedule: rotating 5 on/5 off/4 on, 12-hour day/night shifts. We must not duplicate content. Let's craft. We must output only HTML fragment, no extra text. We'll need to escape any special characters? Probably fine as is. Let's write:

Check we didn't include any boilerplate. We omitted Where You’ll Be Working, About Rio Tinto, Respect and Inclusion. Those are not required sections; we can omit as they are not in the list of allowed headings? The instruction says use headings for those specific sections; we can omit others. It's okay to omit extra info? The instruction: "Preserve ALL substantive information; do NOT invent or summarize away detail." If we omit Where You’ll Be Working and About Rio Tinto, we are losing substantive info. However those are not among the allowed headings list; but we could incorporate that info into About the role or another section? The instruction says use

for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). It doesn't forbid other headings, but says "Use

for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule)." It implies we should use those headings for those sections if present. It doesn't say we cannot add other headings, but we should likely stick to those. However we must
