• Troubleshoot sequence of operations, control logic, and system interactions to resolve performance gaps.
• Analyze trend data, alarms, and system logs to identify inefficiencies, failures, or operational risks.
• Provide high‑level technical guidance to facility teams, operators, and maintenance staff.

Lifecycle Services & Client Partnership

• Serve as a long‑term technical advisor to clients, supporting systems from initial commissioning through ongoing operation.
• Conduct periodic system health assessments and performance reviews.
• Support capital planning by identifying aging equipment, performance risks, and upgrade opportunities.
• Maintain strong client relationships through proactive communication and consistent delivery of value.

Documentation & Reporting

• Prepare clear, detailed reports summarizing findings, energy impacts, and recommended corrective actions.
• Maintain accurate records of system performance, service activities, and lifecycle recommendations.
• Support compliance with healthcare and data‑center standards, including documentation for audits and regulatory reviews.

Qualifications

• Bachelor’s degree in Mechanical, Electrical, or related engineering discipline (or equivalent experience).
• 5+ years of experience in commissioning, building automation, or lifecycle services.
• Strong understanding of HVAC systems, electrical distribution, emergency power, chilled‑water plants, and BAS/BMS controls.
• Proven ability to identify energy‑saving opportunities and optimize system performance.
• Excellent troubleshooting skills with the ability to resolve complex, multi‑system issues.
• Strong communication skills and the ability to translate technical issues into clear guidance for clients.

Preferred Experience

• Healthcare facilities (hospitals, labs, surgical suites) and mission‑critical data centers.
• Retro‑commissioning, monitoring‑based commissioning, or analytics‑driven optimization.
• Familiarity with ASHRAE commissioning guidelines, NFPA codes, and healthcare compliance standards.
• Experience with reliability engineering or mission‑critical operations.
