About Byers Industrial Services

Byers Industrial Services is a leading provider of industrial construction, mechanical services, maintenance, and mission-critical infrastructure solutions. We support some of the most demanding facilities in the country by delivering safe, reliable, and technically superior mechanical solutions. As we continue to expand our data center operations, we are seeking a highly experienced Senior Mechanical Engineer to serve as a technical leader supporting mission-critical cooling infrastructure.

Position Summary

Byers Industrial Services is seeking an experienced Senior Mechanical Engineer with extensive data center mechanical infrastructure experience. This is not a traditional mechanical engineering role—we are looking for a recognized technical expert who understands the unique challenges of operating and maintaining mission-critical cooling systems in live data center environments.

The successful candidate will serve as a primary engineering resource responsible for troubleshooting, optimizing, commissioning, and supporting complex mechanical systems that maintain continuous uptime. This individual must possess deep technical knowledge of data center cooling infrastructure and be comfortable collaborating with operations, commissioning, electrical, controls, and construction teams to ensure the highest levels of reliability, efficiency, and performance.

Candidates MUST have previous data center experience. Applications without direct mission-critical data center mechanical experience will not be considered.

Key Responsibilities

Serve as the subject matter expert (SME) for mission-critical mechanical cooling infrastructure.
Provide engineering leadership supporting the operation, maintenance, troubleshooting, and optimization of live data center mechanical systems.
Analyze mechanical system performance and identify opportunities to improve reliability, efficiency, energy usage, and redundancy.
Diagnose complex mechanical issues affecting mission-critical cooling systems while minimizing operational risk.
Support commissioning, startup, integrated systems testing (IST), and turnover of new mechanical infrastructure.
Review engineering drawings, specifications, sequence of operations, and control strategies for mechanical systems.
Evaluate cooling capacity, airflow management, redundancy, and system resiliency.
Collaborate with facility operations, commissioning agents, controls engineers, electrical engineers, construction managers, and equipment manufacturers.
Develop engineering recommendations for equipment upgrades, lifecycle replacement, and preventive maintenance strategies.
Support emergency response efforts during critical mechanical system events.
Participate in root cause analysis (RCA), failure investigations, and corrective action development.
Ensure compliance with ASHRAE standards, industry best practices, client requirements, and applicable mechanical codes.
Mentor junior engineers and provide technical guidance across project teams.
