Equinix is Recruiting a Specialist Engineer for Our Pantin Site

Equinix is seeking an experienced Specialist Engineer to provide technical leadership and subject matter expertise across our critical infrastructure environment. This role requires fluent English and good French proficiency would be an advantage.

Our business is Data Centers but we are open to all Mission Critical Environments! As a Specialist Engineer, you will serve as a technical authority responsible for ensuring the reliability, availability, maintainability, efficiency and safe operation of the site's critical infrastructure systems. You will provide specialist engineering guidance, oversee maintenance and operational activities, lead technical investigations, support infrastructure improvements, and help drive engineering excellence across the data centre.

This is a highly technical role suited to an experienced engineer with great stakeholder  management and strategic thinking skills.

• Fire detection, suppression and life safety systems
• Building Management Systems (BMS), monitoring and control platforms
• Physical security, access control and critical facility systems
• Asset lifecycle management, maintenance strategy and operational resilience
• Infrastructure capacity planning, optimisation and technical governance

The primary objective of the role is to ensure uninterrupted service delivery through expert stewardship of critical infrastructure while continuously improving reliability, efficiency, resilience and operational performance.

Key Responsibilities

Technical Leadership & Infrastructure Reliability

• Act as the technical authority and subject matter expert for critical facility infrastructure.

• Ensure infrastructure operations align with industry best practice, regulatory requirements and Equinix standards.

Operations, Maintenance & Service Continuity

• Develop and optimise preventative, predictive and reliability-centred maintenance strategies.
• Govern maintenance programmes, asset health and lifecycle planning for critical infrastructure.
• Oversee maintenance activities, contractor delivery, isolations and risk management processes.
• Own and govern BMS, monitoring platforms, alarm management and critical spares strategies.
• Support compliance, audits and technical assurance activities across the facility.

Capacity Planning, Projects & Continuous Improvement

• Monitor infrastructure utilisation and capacity, assessing future growth requirements and operational risks.
• Provide technical leadership for infrastructure upgrades, expansions and capital investment initiatives.
• Lead energy efficiency, sustainability and operational optimisation programmes.
• Support business planning, budgeting, KPI development and long-term asset management strategies.

About You

You will ideally possess:

• Significant experience within data centres, critical facilities, utilities, industrial environments or other mission-critical operations.
• Deep technical expertise across electrical and/or mechanical infrastructure systems.
• Strong knowledge of reliability engineering, maintenance strategy, resilience and operational risk management.
• A proven ability to solve complex technical problems and lead investigations into critical infrastructure issues.
• Excellent stakeholder management and communication skills, with the ability to influence engineering teams, contractors and senior leaders.
• Experience working within structured technical governance, engineering standards and operational frameworks.
• A proactive, continuous improvement mindset with a strong focus on operational excellence.

Desirable Technical Experience

• Chilled water and DX cooling systems
• UPS, standby generation and electrical distribution systems (LV/MV)
• Transformers, switchgear and protection systems
• Building Management Systems (BMS) and monitoring platforms
• Fire detection, suppression and life safety systems
