McCarthy Building Companies, Inc.; Chandler (AZ); On-site; USD 95,000 - 130,000; Full time

Job summary

McCarthy Building Companies, Inc. is seeking an Engineer to own design, procurement, and process workflows for mechanical, piping, HVAC, and plumbing systems within our prefabrication operations. You will bridge detailed design review with material takeoffs and procurement coordination to drive efficiency.

This role emphasizes lean process improvements, data-driven status reporting, and collaboration with project teams to align deliverables with schedule and budget across multiple projects.

Qualifications

• Bachelor’s degree in Mechanical or Industrial Engineering.
• Experience with process piping, HVAC, mechanical and plumbing systems in industrial or construction settings.
• Experience with material takeoffs, BOM creation, procurement coordination, and material tracking.
• Strong ability to read and interpret mechanical drawings, P&IDs, isometrics, specifications, and equipment submittals.
• Proficient in M-Suite for fabrication, material, and workflow data management, and in Microsoft Excel and Word for logs, dashboards, and reporting.
• Experience with construction management and 3D coordination tools preferred.
• Proven ability to build and manage structured workflows for material requisition, approvals, and tracking.
• Strong analytical skills with a focus on data accuracy, repeatable processes, and continuous improvement.
• Effective communicator who can translate technical requirements into clear tasks and data for procurement and operations.
• Highly organized, able to manage multiple projects and priorities in a fast-paced environment.

Responsibilities

• Review mechanical, process piping, HVAC, and plumbing drawings/specs to develop and maintain accurate BOMs and work packages tied to project budgets.
• Validate system layouts, routing, supports, and equipment for constructability and compliance; support shop drawings and installation details with design partners and internal teams.
• Lead material takeoffs for mechanical/process piping and coordinate with procurement to solicit quotes, evaluate proposals, recommend vendors, and manage POs, deliveries, changes, substitutions, and value‑engineering options.
• Develop and maintain material tracking logs and ensure full traceability of materials from requisition through delivery, fabrication, kitting, and installation to specific work packages, spools, areas, and cost codes.
• Collaborate with warehouse, fabrication, and field teams to standardize receiving, inspection, staging, and kitting workflows, and resolve gaps in material data to enable accurate reporting and forecasting.
• Map current engineering–design–procurement–fabrication workflows, identify bottlenecks and rework drivers, and implement lean process improvements, standard templates, and performance metrics (e.g., cycle time, material accuracy, % complete vs. plan).
• Work closely with project management, estimators, procurement, fabrication, accounting, and field teams to align engineering deliverables with schedule and budget, surface material risks early, and provide clear, data-driven status and decision updates.
