Stellar Energy Global Infrastructure (SEGI) is seeking a Senior/Lead Estimator to own the total project cost estimate for our proposals. As a member of the Project Development team, the Estimator works primarily with Business Developers and Technical Developers to compile accurate, defensible estimates. The Estimator develops equipment costs with vendors and labor costs with internal teams, including installation and construction costs with SEGI’s Construction Estimator.

The Estimator serves as custodian of SEGI’s estimating data, ensuring estimates are consistent across all proposals, and continuously feeds actual costs from ongoing projects back into the proposal stage. The role also continuously improves how SEGI estimates, including its tools and processes, to make us faster and more accurate. This is an analytical, decision-making role, not a data-entry role. The Estimator evaluates every input, decides what belongs in the estimate, knows when to seek guidance, and pushes back when numbers do not look correct.

Success is measured by estimates that leadership trusts, that are consistent from one proposal to the next, and that hold up when projects are executed. The Estimator presents and defends estimates to executive leadership with confidence and composure.
