- Evaluate construction submittals, design changes, and modified installations from a reliability and maintainability perspective.
- Support RAM analysis, lifecycle analysis, spare parts strategy, and site response planning for cooling systems.
- Mentor less experienced reliability engineers and guide technical problem solving across the mechanical specialty.
Ideal Candidate Profile- 6-10 years of experience in critical cooling, HVAC, mechanical reliability, commissioning, or uptime-critical infrastructure environments.
- Deep familiarity with cooling-system arrangements, component failures, automation interfaces, and larger system effects.
- Experience leading RCAs, maintenance optimization, and technical support in live mechanical plant environments.
- Bachelor's degree in Mechanical Engineering or related field preferred; equivalent experience also valued.
Skills and Competencies- Strong systems thinking and technical judgment for mechanical infrastructure.
- Strong analytical capability using maintenance history, performance data, and failure trends.
- Ability to influence operational and design decisions without formal authority.
- Strong communication and mentoring capability.
