The Role

The Senior Estimator at GeoStabilization International is not a back-office cost compiler. This role is a strategic operator who converts incomplete information, complex geology, and constrained schedules into disciplined, winnable cost strategies.

You will lead multiple, high-stakes estimates simultaneously—often under uncertainty—partnering closely with Engineering, Project Development, and Operations. While this role does not carry direct people management responsibility, it demands leadership, technical credibility, and the ability to elevate the estimating discipline across the organization.

This is a role for individuals with Director-level runway—those who consistently demonstrate judgment, clarity of thought, and measurable impact.

What You Will Own

Estimating & Commercial Leadership

• Act as Lead Estimator on multiple concurrent pursuits, often with limited documentation and aggressive timelines.
• Develop conceptual through IFC-level budgets, translating ambiguity into executable cost plans.
• Perform detailed takeoffs for self-performed work and validate subcontractor scopes for completeness and risk alignment.
• Build and present defensible, margin-aware estimates that support go/no-go decisions and win strategies.
• Lead estimate reviews and bid strategy sessions with Engineers, PMs, Superintendents, and Executives.

Cross-Functional Influence

• Serve as a subject matter expert for heavy civil, geotechnical, and specialty construction estimating.
• Mentor and review work prepared by Estimators and partners—raising quality, discipline, and repeatability.
• Collaborate with Engineering to align means & methods, constructability, and risk assumptions.
• Present estimates and commercial strategies to internal leadership and external Owners/Architects.

Market & Bid Strategy

• Develop pursuit strategies that balance competitiveness, risk, and profitability.
• Evaluate subcontractor and supplier bids; lead scope reconciliation and final buyout recommendations.
• Participate in pre-bid meetings, site visits, and owner presentations as required.
• Continuously improve estimating processes, tools, and data quality (B2W preferred).

Required Qualifications (Table Stakes)
