Senior Cost Engineer

As a Senior Cost Engineer, you develop detailed cost estimates for engineering projects, track budgets through execution, and analyze variances when reality diverges from the plan. Your estimates aren't guesses — they're built from historical data, vendor quotes, labor rates, and material indices. The senior title means you're typically leading the estimating function on major projects and advising leadership on cost risk.

Your day balances spreadsheets and site walks. You might spend the morning building a bottom-up estimate for a capital project, then review change orders with the project team, then update the cost forecast based on procurement delays. You need to understand both the engineering scope and the commercial reality — knowing what things should cost and what they will cost are different skills.

The challenge is accuracy under uncertainty. Early-stage estimates might have 30% accuracy ranges, and stakeholders still want firm numbers. You're constantly managing expectations while refining estimates as design progresses. The best cost engineers combine technical knowledge with commercial instinct — they can spot when a contractor's bid is too low to be real or when scope creep is about to blow the budget.
