Mobile Maintenance Supervisor

We need to output HTML fragment with sections: About Us? Actually "About Us" is not a required heading per rules: headings allowed: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. The posting includes "About Us" which is not in list; we should not create a heading for it unless it maps to allowed headings. The content about company could be considered "About the role"? No, it's about company. The rules say use

for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). So only those headings allowed. We must not repeat job title as heading. We need to include sections only when posting has real specific content for it. We have content: Position Overview (could map to About the role). Key Responsibilities (Responsibilities). Qualifications (Qualifications). Preferred Qualifications could be under Skills? Or maybe Requirements? The posting includes Qualifications and Preferred Qualifications. We could combine them under Qualifications and maybe Skills. But we need to preserve all substantive info. We can have sections: About the role (position overview), Responsibilities (key responsibilities), Qualifications (qualifications + preferred qualifications maybe as sublist), Skills (maybe extract skills from qualifications). However we must not invent sections with filler. If we put Skills but no explicit skills list, we might be inventing. Better to only include sections that match content: About the role, Responsibilities, Qualifications. Possibly also Requirements? The qualifications already cover requirements. Could treat Qualifications as Requirements. But we have both Qualifications and Preferred Qualifications; we could put them under Qualifications heading. We must not include Benefits, Pay, Schedule because not mentioned. We must not include cookie/navigation etc. We need to output only HTML fragment, using

for headings,

• for lists,

  for prose. We need to preserve all substantive information: About Us description, Position Overview, Key Responsibilities bullet list, Qualifications bullet list, Preferred Qualifications bullet list. We need to decide how to structure. Option:

  About the role

  then

  containing Position Overview paragraph plus maybe About Us? But About Us is company info, not role. Could we include About Us as part of About the role? Might be okay but risk of misrepresenting. However instructions: "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 those for section headings. Likely they expect only those headings. So we should map content to those headings. About Us could be considered "About the role"? Not ideal but maybe we can include it under About the role as background. Or we could omit About Us? But we must preserve ALL substantive information. So we need to include it somewhere. Could put it in a

  before the first heading? The instructions: "Output ONLY the HTML fragment — no /, no markdown code fences." It didn't forbid having a leading paragraph before any heading. So we could have a

  with About Us, then

  About the role

  etc. That preserves info. Thus structure:

  About Us Solidus Resources is a U.S.-based gold development company ... (the whole About Us paragraph).

  About the role

  Position Overview The Mobile Maintenance Supervisor leads a team supporting mobile equipment at an autonomous gold mining operation. This hands-on leadership role requires regular time in the shop and field to provide technical guidance, set priorities, and hold the team accountable for safety, performance, and operational KPIs. The supervisor oversees maintenance across drills, shovels, haul trucks, loaders, dozers, graders, light vehicles, and auxiliary equipment. The role is not expected to perform every repair but must have the technical knowledge to guide employees and support troubleshooting.

  Responsibilities

  • Lead the mobile maintenance team during assigned shifts, providing clear day-to-day direction, coaching, and technical guidance.
  • Oversee maintenance activities across the production and support fleet.
  • Maintain a regular presence in the shop and field to support employees, monitor work, and help resolve equipment issues.
  • Prioritize work and coordinate with maintenance control and other departments to support operating needs.
  • Manage KPIs, deliverables, and performance expectations while holding employees accountable for safe, effective work.
  • Promote compliance with MSHA regulations, site safety requirements, and equipment-isolation procedures.
  • Support autonomous operating-zone training, including train-the-trainer responsibilities for the maintenance department.
  • Maintain clear shift handovers, equipment-status updates, safety records, repair documentation, reports, files, and email communication.
  • Develop team members and identify employees who can provide second-in-command coverage when required.

  Qualifications

  Five or more years of mobile equipment maintenance experience, preferably in an open-pit mining operation.

  Three to five years of relevant experience as a lead person, foreman, supervisor, or maintenance planner with leadership responsibilities.

  Working knowledge of diesel engines, diesel-electric drive systems, high-pressure hydraulics, electrical and electronic controls, and OEM troubleshooting practices.

  Experience supporting production and auxiliary equipment such as haul trucks, shovels, loaders, drills, dozers, graders, water trucks, service equipment, and light vehicles.

  Experience using a computerized maintenance management system to review work orders, equipment history, backlog, labor assignments, downtime, and repair documentation.

  Knowledge of preventive and planned maintenance, breakdown response, major repairs, component changeouts, and basic failure-analysis practices.

  Understanding of MSHA requirements, lockout/tagout, stored-energy control, equipment isolation, and mine-site safety practices.

  Ability to provide firm, consistent direction, manage KPIs and deliverables, and hold employees accountable in a fast-paced operating environment.

  Basic proficiency with Microsoft Office, including Excel and Outlook, as well as electronic file and maintenance reporting systems.

  Valid driver's license and ability to obtain required MSHA, site, autonomous operating-zone, and equipment-specific authorizations.

  High school diploma or GED required. Heavy-equipment, diesel, electrical, mechanical, or related trade training is preferred. A technical diploma, associate degree, bachelor's degree, or equivalent practical mining-maintenance experience will be considered.

  We could also include Preferred Qualifications as a subsection under Qualifications or as a separate

  Skills

  . Since we have a Skills heading allowed, we could put Preferred Qualifications under Skills. But we must not create a heading with filler. The Preferred Qualifications are substantive. So we could do:

  Skills

  list of preferred qualifications. But the Preferred Qualifications are a list of items each starting with "Experience with ..." etc. Could be represented as
  • . That would be appropriate. Thus we have sections: About the role, Responsibilities, Qualifications, Skills. We must not repeat job title as heading. Not include Pay/Benefits/Schedule. Now we need to ensure we preserve all substantive info: About Us paragraph, Position Overview paragraph, Responsibilities list, Qualifications list (the many bullet points), Preferred Qualifications list. We must not invent or summarize away detail. So we need to keep each qualification as separate bullet or paragraph. The original qualifications are a paragraph separated by periods. We could keep them as

    each sentence, or combine into

    • . The instruction: Use
      • for any list of duties/requirements/benefits. Qualifications are requirements, so we should use
        • . Similarly for Preferred Qualifications (skills). So we should convert each qualification into list items. Thus:

          Qualifications

          • Five or more years of mobile equipment maintenance experience, preferably in an open-pit mining operation.
          • Three to five years of relevant experience as a lead person, foreman, supervisor, or maintenance planner with leadership responsibilities.

          Now About Us paragraph: we need to preserve all content. Let's copy exactly the About Us paragraph from the posting: "About Us Solidus Resources is a U.S.-based gold development company backed by Waterton Mining.
