Ensure reliability practices are consistently applied across all sites.

Equipment Performance Monitoring

Establish monitoring frameworks for critical infrastructure equipment performance.
Analyse operating data from electrical and mechanical systems to identify degradation trends.
Monitor redundancy utilisation, abnormal operating conditions, and reliability indicators.
Identify early warning signals for potential equipment failures.

Failure Analysis & Root Cause Investigation

Lead structured Root Cause Analysis (RCA) for major infrastructure incidents.
Perform failure mode analysis using fault tree and event chain methodologies.
Identify recurring failure mechanisms across sites.
Ensure lessons learned from failures are captured and shared across the organisation.

Reliability Risk Assessment

Assess reliability risks associated with infrastructure design, operations, and vendor equipment.
Evaluate cross-campus failure exposure and correlated infrastructure vulnerabilities.
Provide technical recommendations to mitigate systemic reliability risks.

Reliability Data Analytics & Reporting

Develop reliability performance dashboards and trend analysis.
Monitor incident frequency, failure severity, and infrastructure performance trends.
Provide reliability reports and insights to engineering and executive leadership.

Reliability Improvement Programs

Lead initiatives to improve infrastructure resilience and reliability.
Identify reliability improvement opportunities across systems and sites.
Validate effectiveness of remediation and reliability improvement actions.

Lifecycle & Obsolescence Management

Define strategies for managing aging infrastructure and equipment lifecycle risks.
Assess replacement versus lifeextension strategies for critical infrastructure systems.
Support long-term infrastructure planning from a reliability perspective.

Vendor & OEM Reliability Oversight

Evaluate vendor reliability performance and technical claims.
Assess OEM failure rates and design-related reliability exposure.
Collaborate with vendors to address systemic equipment reliability issues.

Cross-Team Collaboration

Work closely with DCO teams, Engineering Authorities, Design Teams, and external vendors.
Support reliability engineering input into ROCC and MCR operational frameworks.
Promote knowledge sharing and reliability best practices across the organisation.

Candidate Requirements

Bachelor's degree in Engineering (Electrical, Mechanical, or related discipline).
10+ years experience in missioncritical infrastructure
Strong experience in equipment reliability analysis, failure investigation, and RCA
Deep understanding of electrical and mechanical systems in data centre environments.
Proven ability to identify systemic reliability risks and implement mitigation strategies.
Strong analytical and problemsolving capabilities.
Experience working across multiple sites or regional infrastructure portfolios preferred.
Excellent communication and stakeholder management skills.
Willingness to travel across regional sites when required.
