Mariana Minerals is a software-first, vertically integrated minerals company supplying critical minerals for modern energy, AI, and defense technologies.

As 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 will be the primary quality interface between site teams, Construction Management, Field Engineering, Design Engineering, Process Engineering, Supply Chain, contractors, vendors, and Operations, setting consistent quality standards across all builds.
Key responsibilities include:
- Lead site quality activities across construction, installation, testing, commissioning, handover, and closeout on every 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 company quality requirements are understood and verified in the field.
- 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.
- Initiate, investigate, and close NCRs, deviations, punch-list items, and corrective actions with clear objective evidence.
- Lead root cause analysis and corrective/preventive action with site teams, engineering, contractors, and suppliers.
- Manage site quality records, including inspection reports, test records, commissioning records, and turnover packages.
- Compile quality data books, dossiers, and closeout packages.
- Hold contractors, vendors, and site suppliers to quality requirements, site procedures, and specifications.
- Monitor contractor and vendor quality performance and drive resolution of issues.
- Collaborate with software engineering to digitize ITPs, inspection records, and NCR tracking.
- Promote a safe work culture and build safety and environmental requirements into inspection and acceptance criteria.
- Willingness to travel frequently to project, supplier, and manufacturing sites.
Requirements:
- Bachelor's degree in Engineering, Construction Management, Quality Management, or a related technical field; or equivalent experience.
- Experience in construction, commissioning, field, or project quality on industrial, mining, processing, or power generation projects.
- Hands-on experience with ITPs, quality plans, witness and hold points, NCR management, root cause analysis, and corrective/preventive action.
- Ability to interpret specifications, contracts, drawings, procedures, and acceptance criteria, including applicable codes and standards.
- Experience with mechanical, electrical, dimensional, welding, coating, NDE, calibration, or commissioning inspection preferred.
- Auditing experience (supplier or site audits) preferred.
- Proficiency with Microsoft Office, document management systems, and digital quality or tracking tools.
- Excellent communication, judgment, and decision-making abilities, with the ability to influence without direct authority across multiple teams and sites.
- Highly organized and detail-oriented, able to manage multiple sites, inspections, and open actions at once.
- Experience with EPC/EPCM delivery models highly desirable.
