> Own fleet reliability for nation-scale AI data centers: set availability targets, perform RCA on major incidents, build failure data pipelines, and define data-driven maintenance strategies. Requires hands-on experience improving critical infrastructure availability using Weibull, Pareto, and FMEA.

## Job Description

## Own fleet reliability engineering
- Define availability targets, measure them honestly, and close the gap to targets.
- Run root cause analysis on the fleet's worst incidents and drive corrective actions to completion across every site.
- Build the failure data pipeline (facility and hardware) that turns incident history into engineering priorities.
- Set the maintenance strategy (reliability-centered, condition-based) so the fleet spends effort where the failure data indicates.

## Requirements
- Owned reliability for critical infrastructure and moved the availability number (not just reported it).
- Led root cause analyses that found the real cause, not the convenient one.
- Work fluently with failure data: Weibull, Pareto, and FMEA are tools you actually use.
- Get corrective actions closed across teams you do not manage.

## Nice-to-haves
- Data center or power generation reliability.
- Liquid cooling systems.
- CMMS analytics.
- CRE or CMRP certification.
