Senior Estimator (Power Generation)

About Fermi America

Fermi America is developing the world’s largest next-generation private power grid to support the future of artificial intelligence. As hyperscale AI demand rapidly outpaces the capabilities of the legacy grid, Fermi is pioneering a behind-the-meter HyperGrid™ delivering highly redundant, utility-scale power at unprecedented speed and scale.

Our flagship development near Amarillo, Texas will exceed 12 GW of generation capacity, including 6 GW of natural gas and 6 GW of nuclear, supporting more than 15 million square feet of high-density data center infrastructure. This is not incremental infrastructure. It is sovereign-scale power development.

Position Summary

 The Estimator will serve as a capital and cost-modeling authority for Fermi America’s power and infrastructure program. This role goes far beyond traditional estimating or cost accounting. You will own the capital cost modeling, validation, and risk analysis for one of the largest behind-the-meter generation and data center developments ever undertaken in the United States.

You will be responsible for developing decision-grade cost estimates across the full project lifecycle, from early feasibility through execution-ready control budgets, spanning simple-cycle and combined-cycle natural gas generation, high-pressure gas infrastructure, high-voltage substations, and large-scale data center construction.

As an in-house estimator embedded with engineering, procurement, and construction leadership, your work will directly inform investment decisions, EPC strategy, procurement sequencing, and executive-level capital allocation.

Key Responsibilities

Capital Cost Estimation & Modeling

• Develop,      maintain, and continuously refine Class 5 through Class 1 capital cost      estimates for large-scale energy and infrastructure projects, including      utility-scale simple-cycle and combined-cycle gas turbine plants (CCGT),      HRSG systems, cooling infrastructure, balance-of-plant, substations, and      high-voltage interconnections.  
• Produce      integrated capital cost models supporting feasibility analysis, project      sanctioning, execution planning, and cost control, aligned with evolving      engineering maturity and delivery strategies.  
• Perform      detailed quantity takeoffs and bottoms-up cost modeling, validating      engineering assumptions and modeling labor, material, equipment,      indirects, escalation, and contingency across civil, mechanical,      electrical, I&C, and balance-of-plant scopes.  

EPC, OEM, and Procurement Interface

• Support      EPC and OEM bid evaluation and bid leveling, performing detailed scope,      commercial, and assumption reviews to ensure completeness, risk alignment,      and market-competitive pricing.  
• Collaborate      with engineering and procurement teams to define owner-furnished versus      contractor-furnished scopes, optimize cost, schedule, and risk.  
• Track      and incorporate commodity pricing trends, labor market conditions, and      long-lead equipment dynamics, including turbines, transformers,      generators, steel, and copper, into estimates and escalation      assumptions.  

Risk, Sensitivity, and Value Engineering

• Conduct      risk, sensitivity, and scenario analyses to evaluate cost exposure under      varying economic, schedule, and execution assumptions, clearly      articulating downside, upside, and mitigation strategies.  
• Identify      and support value engineering and cost optimization opportunities,      including constructability improvements, scope refinement, and integration      efficiencies between generation assets and data center load.  
• Benchmark      costs against comparable utility, EPC, and hyperscale infrastructure      projects to validate assumptions and identify gaps. 

Stakeholder & Executive Support

• Serve      as a trusted cost advisor to engineering, construction, finance, and      executive leadership, ensuring alignment between technical design, cost,      and commercial strategy.  
• Prepare      clear, executive-ready cost breakdowns, summaries, and decision-support      materials for senior leadership, investment committees, and external      stakeholders.  

  Experience

• 10+      years of experience in industrial or infrastructure estimating, with at      least 5 years focused on utility-scale power generation or heavy      industrial projects with capital budgets exceeding $500 million.  
• Demonstrated      experience estimating simple-cycle and combined-cycle natural gas      generation projects, including turbine procurement, HRSGs, cooling      systems, and high-voltage electrical infrastructure.  

Technical Expertise

• Strong      understanding of natural gas power plant architecture, EPC delivery      models, high-voltage transmission and substations, and large-scale data      center or industrial facility construction.  
• Proven      ability to develop estimates across all project phases, from conceptual      studies through execution-ready budgets. 

Tools & Systems

• Expert-level      proficiency in HCSS HeavyBid, WinEst, Sage Estimating, or equivalent      industry-standard estimating platforms.  
• Advanced      Excel-based financial and cost modeling skills, including scenario and      sensitivity analysis.  

Market & Contract Knowledge

• Strong      knowledge of the Texas energy market (ERCOT) and regional labor and      subcontractor dynamics.  
• Experience      with a range of contract structures, including Lump Sum, GMP, and      Cost-Plus with Target Price arrangements.  

Education

• Bachelor’s      degree in Construction Management, Mechanical Engineering, Electrical      Engineering, or a related field.  

Why Fermi America

• Unmatched      Scale: Work on a nationally significant, multi-gigawatt power and      infrastructure program unlike anything else in development today.  
• Direct      Impact: Your work directly shapes capital allocation, EPC strategy,      and execution outcomes at the highest levels of the organization.  
• Owner-Side      Authority: This is not a consulting or transactional role. You sit at      the center of decision-making.  
• Speed      and Precision: We value technical rigor, decisiveness, and execution      velocity over bureaucracy.
