About the role

AI summarised

The Costing Engineer at Micron Technology is responsible for end-to-end cost estimation, control, and reporting for semiconductor fab construction projects. This role develops benchmarked cost models, supports design-to-cost decisions, leads tendering processes, and ensures predictable CAPEX outcomes for cleanrooms, subfab structures, UHP utilities, abatement, and high-density electrical/mechanical systems. The engineer collaborates across Facilities Engineering, Tool Install, Process/Equipment Engineering, QS/Commercial, Procurement, and Planning 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.
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.
Lead Quantitative Cost Risk Analysis (QCRA); model scenarios for commodity volatility (stainless/copper), lead times (switchgear/chillers), UHP welding productivity, certification failures.
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.
Good analytical skills with problem solving aptitude.
