Senior Mechanical Commissioning Manager

Lead the startup of major process systems

This is an opportunity for a senior commissioning leader who knows how to take complex mechanical and process systems from turnover to safe, reliable operation. You will own mechanical commissioning and startup for a major West Texas oil and gas project, working directly with construction, operations, engineering, vendors, and the client to move systems through completion, testing, first run, performance verification, and final handover.

You will have the field authority to set priorities, identify readiness risks, drive punch-list closure, and make the decisions that protect people, equipment, schedule, and startup milestones. The role is focused on mechanical and process systems; electrical and instrumentation teams will be key interfaces, but this is not an electrical commissioning lead position.

• Senior-level ownership of mechanical commissioning and startup on a major industrial project.
• Strong hourly compensation with overtime and daily per diem.
• A field leadership role with direct visibility to project and client leadership.
• Work across compressors, pumps, drivers, vessels, exchangers, piping, utilities, and packaged process equipment.
• The opportunity to shape turnover strategy, startup readiness, troubleshooting, and final handover.

• Develop and execute the commissioning and startup plan, including system boundaries, turnover sequence, staffing, schedule, priorities, and acceptance criteria.
• Lead mechanical completion, pre-commissioning, commissioning, startup, stabilization, performance testing, and turnover.
• Systemize facilities using P&IDs, process flow diagrams, equipment lists, line lists, and turnover packages.
• Direct readiness and commissioning activities for compressors, pumps, turbines or drivers, separators, vessels, exchangers, fired equipment, tanks, piping, valves, utilities, and packaged equipment.
• Oversee pressure testing, flushing, blowing, chemical cleaning, leak testing, drying, inerting, lubrication, alignment verification, rotation checks, preservation removal, and equipment readiness.
• Verify completion records, test packages, inspection records, vendor documentation, punch lists, and turnover dossiers before startup authorization.
• Coordinate construction, operations, engineering, quality, safety, controls, vendors, subcontractors, and client representatives.
• Lead walkdowns and drive Category A, B, and C punch-list closure based on startup risk and turnover requirements.
• Maintain the commissioning schedule, turnover forecast, constraint log, manpower plan, daily execution plan, and progress reporting.
• Develop and approve commissioning procedures, startup sequences, check sheets, test records, operating readiness reviews, and acceptance documentation.
• Coordinate vendor representatives through installation verification, first run, troubleshooting, warranty requirements, and performance testing.
• Lead field troubleshooting and root-cause resolution during startup and early operation.
• Control simultaneous operations, permits, isolations, line breaking, confined-space work, pressure testing, and startup energy hazards.
• Drive final handover to operations with complete records, operator training, spare-parts status, approved exceptions, and clear ownership of outstanding items.

• 12 or more years of progressive commissioning, startup, construction, operations, or maintenance experience in oil and gas, gas processing, midstream, petrochemical, refining, or comparable heavy industrial facilities.
• At least 5 years leading commissioning or startup teams on major field projects.
• Hands‑on knowledge of rotating equipment, fixed equipment, piping, pressure systems, valves, utilities, and packaged equipment.
• Strong understanding of mechanical completion, systemization, turnover, preservation, pre-commissioning, startup, performance testing, and final acceptance.
• Ability to read and apply P&IDs, process flow diagrams, equipment data sheets, plot plans, isometrics, vendor manuals, cause‑and‑effect documents, and turnover records.
• Proven ability to lead multidisciplinary field teams and make sound decisions in active construction and startup environments.
• Working knowledge of applicable industry practices and standards, including API, ASME, OSHA, and client‑specific commissioning requirements.
• Strong planning,…
