• Help manage subcontractor buyout, scope reviews, and contract coordination
• Maintain and track RFIs, submittals, and project documentation (Procore/Bluebeam)
• Coordinate between field, design teams, and ownership groups to keep communication tight
• Assist with QA/QC and DSA compliance requirements
• Support closeout, punchlists, and final turnover
What They’re Looking For
• 3+ years of experience supporting construction projects (ideally DSA, K-12, or public works)
• Exposure to California public contracting + DSA processes is a big plus
• Comfortable with Procore, Bluebeam, MS Project
• Strong attention to detail, organization, and ability to keep things moving
• Degree in Construction Management, Civil Engineering, or related preferred
Compensation / Benefits
• Competitive base + performance bonus
• 401(k) with match
• Medical covered (plus vision/dental options)
• FSA + long-term disability
• PTO, holidays, and sick time
