About the role
The Costing Engineer is responsible for end-to-end cost estimation, control, and reporting across semiconductor fab construction (base-build). This role involves developing benchmarked, defensible cost models, supporting design-to-cost decisions, driving tendering/commercial rigor, and ensuring predictable CAPEX outcomes for cleanrooms, subfab structures, ultra-high purity (UHP) utilities, abatement, and high-density electrical/mechanical systems. The role requires collaboration with various engineering and commercial teams to deliver cost certainty from feasibility through handover.

Key Responsibilities
- Build Class 5–3 estimates for greenfield fabs, brownfield expansions, and capacity upgrades.
- Develop parametric cost models (cost per sqft cleanroom, per utility density) and maintain historical benchmarks by technology node and region.
- Identify scope/risks for cleanrooms (ISO 3–7), subfab, UPW/WWT, CDA/N₂, HPM gases, exhaust & abatement, electrical distribution, chilled water/HVAC.
- Provide design‑to‑cost inputs on cleanroom type, plenum heights, slab/vibration criteria (VC‑A to VC‑E), redundancy (N+1/2N), and specialty materials (FM‑approved, chemical‑resistant).
- Quantify and compare alternatives (modular utility skids vs stick‑build, ceiling grid/FFU density, substrate/trench layouts) with TCO/ROI implications.
- Align estimates with facility load from Process/Equipment Engineering and Line Planning.
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 experience with 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, power & mechanical redundancy, and vibration criteria.
- Good analytical skills with problem-solving aptitude.
