• Assist with cost tracking, change orders, and estimate reconciliation on awarded projects as needed
• Mentor and support junior estimators as appropriate while remaining directly involved in estimate development
• Perform additional assignments to support the Estimating team

QUALIFICATIONS

• Bachelor's degree in Construction Management, Engineering, or a related field (or equivalent technical training)
