• Manage assignments within schedule, budget, and quality expectations

Technical Expertise & Problem Solving

• Evaluate HVAC, chillers, boilers, pumps, and automation systems
• Troubleshoot system performance issues

Client Engagement

• Lead meetings and communicate findings
• Build relationships with clients and contractors

Operational Contributions

• Complete reports and manage time and expenses

Team Development

• Mentor junior engineers and support training
