About the role

AI summarised

The Costing Engineer at Micron Technology is responsible for developing accurate cost estimates and financial models for semiconductor fab construction and expansion projects, including greenfield and brownfield facilities. This role involves parametric modeling, risk analysis, compliance verification, and stakeholder coordination across engineering, procurement, and project management teams to support capital investment decisions. The position requires deep expertise in cleanroom systems, UHP utilities, and industrial construction estimating, with strong analytical and communication skills to defend estimates and drive value engineering.

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
Prepare BOQs, rate build‑ups, and bid packages across C/S/A/M/E/P scopes if required
Lead RFQ/RFP processes: clarify scope, normalize bids, validate inclusions/exclusions (HPM compliance, seismic supports, cleanroom finishes)
Create and defend should‑cost breakdowns for UHP piping, gas cabinets, bulk/CDA/N₂ systems, scrubbers/abatement, electrical switchgear, and modular skids
Ensure compliance with FM Global, NFPA/IFC, SCDF requirements, local codes, and internal audit
Keep documentation audit‑ready (assumptions, sources, bid tabs, approvals)

Requirements

Bachelor’s degree in Quantity Surveying, Mechanical/Electrical Engineering, Construction Management, Industrial Engineering, or related field
Master’s degree is a plus
5–10+ years of cost engineering/estimating experience, with semiconductor fab or advanced manufacturing projects (cleanrooms, UHP, tool‑install) strongly preferred
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
