About the role

AI summarised

The Costing Engineer is responsible for end-to-end cost estimation, control, and reporting across semiconductor fab construction (base-build). This role develops benchmarked, defensible cost models, supports design-to-cost decisions, drives tendering/commercial rigor, and ensures predictable CAPEX outcomes for critical cleanroom, subfab, UHP utilities, abatement, and high-density electrical/mechanical systems.

Key Responsibilities

Build Class 5–3 estimates for greenfield fabs, brownfield expansions, and capacity upgrades.
Develop parametric cost models (e.g., cost per sqft cleanroom, per utility density) and maintain historical benchmarks.
Provide design-to-cost inputs on cleanroom type, plenum heights, vibration criteria, and redundancy levels.
Lead RFQ/RFP processes, including clarifying scope, normalizing bids, and validating inclusions/exclusions.
Create and defend should-cost breakdowns for UHP piping, gas cabinets, abatement systems, electrical switchgear, and modular skids.
Lead Quantitative Cost Risk Analysis (QCRA) by modeling scenarios for commodity volatility and lead times.
Produce monthly cost reports, VE registers, risk logs, cash flow updates, and executive summaries.
Interface cross-functionally with Facilities Engineering, Procurement, QS/Commercial, and suppliers to deliver cost certainty.

Requirements

Bachelor’s degree in Quantity Surveying, Mechanical/Electrical Engineering, Construction Management, Industrial Engineering, or related field.
5–10+ years of cost engineering/estimating experience.
Strong preference for semiconductor fab or advanced manufacturing projects (cleanrooms, UHP, tool-install).
Demonstrated competency in BOQ take-offs, rate build-ups, estimating classes, tender evaluations, and cost control.
Solid understanding of cleanroom systems, UHP piping, HPM compliance, abatement, and mechanical redundancy.
Proficiency in Microsoft Excel and ability to use simple code writing for analysis.
