The Opportunity

Chandos is seeking a Senior Estimator to lead estimating on a long-term nuclear project at Chalk River, supporting continued growth across Ontario.

This role is suited to a highly proactive Senior Estimator who takes ownership, a multiplier who drives timelines, and follows through relentlessly to close gaps, align stakeholders, and produce competitive, accurate bids in a complex environment.

Why This Role

A critical role on a long-standing nuclear project, where success depends on ownership, follow-through, and the ability to drive outcomes in a complex delivery environment.

What You’ll Own

• Subtrade engagement, pricing strategy, and bid development
• Risk, contingency, and commercial assumptions that protect margin and win work

• A disciplined, organized approach to delivering complete and accurate estimates

What Sets You Apart

• You drive progress without waiting, especially when inputs are incomplete or moving
• You follow up, close gaps, and keep people aligned to deadlines
• You balance detail with judgment, knowing when “complete” is better than “perfect”
• You are comfortable operating in complex, multi-stakeholder environments
• You take ownership of outcomes, not just inputs

Core Capability Requirements

• Prepare and lead full-cost estimates across conceptual to detailed phases
• Develop labour, material, and equipment pricing with strong market awareness
• Evaluate risk, escalation, and contingency to support sound commercial decisions
• Lead subtrade solicitation, bid analysis, and pricing strategy
• Support bid strategy, value engineering, and client presentations

Minimum Qualifications (Non Negotiable)

• 10+ years of estimating experience in nuclear or heavy industrial construction
• Proven experience on large-scale ($1B+) projects or equivalent complexity
• Strong experience from a general contractor environment
• Demonstrable experience leading teams and driving for results
• Advanced proficiency in Excel and estimating tools
• Ability to lead estimating efforts and coordinate cross-functional input
