Senior Mechanical Engineer (Data Centers)

On-siteDallas, Texas, United States

Full TimeSenior LevelMediumFinance

Job Summary

Provide mechanical engineering input during site selection, design reviews, and construction document evaluations to ensure operational readiness and system redundancy. Support the full lifecycle from construction and commissioning through turnover, validating alarms, controls sequences, and BMS visibility for safe site handoff. Serve as the technical escalation point for incidents, analyzing performance trends and leading root cause analyses to develop corrective actions that reduce repeat failures. Define preventative maintenance standards, manage asset criticality frameworks, and own water treatment monitoring programs to protect system integrity. Develop engineering standards, operating playbooks, and training content to strengthen internal technical capability and reduce reliance on external consultants.

Required Qualifications

  • Bachelor's degree in Mechanical Engineering or a closely related technical discipline
  • 8-10 years of progressive mechanical engineering experience
  • at least 5 years supporting data centers, mission-critical facilities, central plants, industrial facilities, or other 24x7 high-availability environments
  • Demonstrated experience supporting mechanical infrastructure across design review, construction support, commissioning, turnover, maintenance, troubleshooting, and enduring operations
  • Strong working knowledge of data center or mission-critical mechanical systems, including cooling plants, air handling systems, pumps, heat rejection equipment, piping, valves, controls, and redundancy configurations
  • Experience reviewing mechanical drawings, equipment submittals, sequence-of-operations documents, commissioning scripts, test reports, O&M manuals, and maintenance documentation
  • Ability to troubleshoot complex mechanical issues in live operational environments and make sound recommendations that balance uptime, safety, cost, schedule, and long-term reliability
  • Experience with preventative maintenance, root cause analysis, corrective action planning, asset lifecycle management, and operational risk assessment
  • Strong communication skills with the ability to explain technical issues clearly to site operations, leadership, vendors, design teams, construction teams, and commissioning partners

Desired Qualifications

  • 10+ years of mechanical engineering experience in large-scale data center, mission-critical, or multi-site critical infrastructure environments
  • Professional Engineer license or Engineer-in-Training certification
  • Experience serving as a senior mechanical technical escalation point for live operational facilities
  • Experience supporting new data center builds, major expansions, retrofits, integrated systems testing, and operational turnover
  • Knowledge of Uptime Institute Tier concepts, ASHRAE guidance, OEM maintenance requirements, and data center availability expectations
  • Experience with BMS platforms, mechanical controls troubleshooting, alarm strategy, trend analysis, and sequence optimization
  • Familiarity with predictive maintenance technologies, thermal modeling, CFD, digital asset management, CMMS data quality, or reliability analytics
  • Experience developing mechanical standards, SOPs, MOPs, EOPs, RCA templates, training materials, and engineering governance processes
