Construction & Commissioning Quality Engineer at Marianaminerals · LumiJobs

Responsibilities

As a Construction & Commissioning Quality Engineer, you will lead site quality across all of Mariana Minerals’ industrial process facilities, from construction and installation through testing, commissioning, handover, and project closeout. You’ll make sure quality requirements are built into field execution, verified at every hold point, and documented so each plant is turned over complete, compliant, and ready to run.
This is a company-wide role covering every Mariana Minerals project, not a single site. You’ll be the primary quality interface between site teams, Construction Management, Field Engineering, Design Engineering, Process Engineering, Supply Chain, contractors, vendors, and Operations, and you’ll set consistent quality standards across all of our builds. Your work will be vital to building plants that start up safely, reliably, and right the first time.
Site Quality Leadership & Planning:
Lead site quality activities across construction, installation, testing, commissioning, handover, and closeout on every Mariana Minerals project.
Develop and execute site-specific Quality Plans, Inspection and Test Plans (ITPs), inspection checklists, and quality schedules.
Ensure contractual, regulatory, local statutory, environmental, and Mariana Minerals quality requirements are understood and verified in the field.
Support kick-off meetings, handovers to site and commissioning teams, project coordination meetings, and final handover reviews.
Inspections & Commissioning Quality:
Execute C&C ITPs and verify that inspections, tests, witness points, hold points, and acceptance criteria are completed per project requirements.
Coordinate internal and third-party inspection resources for mechanical, electrical, dimensional, welding, coating, NDE, calibration, and functional testing.
Plan and run witness inspections, site audits, and surveillance activities, including readiness checks, required equipment, and calibration status.
Ensure nonconforming work is not built upon, concealed, or handed over until it is dispositioned and corrected.
