Senior Data Center Operations Engineer M/F

📍 Paris / Île-de-France | Data Center Environment | Permanent Contract | Multisite Scope

Join my client at the heart of critical infrastructure.

In a context of strong growth and infrastructure development, my client is strengthening its Operations organization in France and creating a Chief Engineer position.

Within a new transverse technical expertise hub, you will become the technical referent for operations across several strategic sites in France, with a priority scope covering two sites in particular.

Your mission: to bring your expertise, secure operations, and contribute to advancing the entire organization towards greater standardization, operational rigor, and technical excellence.

This position is for an experienced individual who wants to go beyond pure technical expertise and play a central role in the structuring of operations for a fast-growing Data Center player.

Your Missions

Your Role

The Chief Engineer acts as a multisite technical and operational referent.

You will be:

• a technical expert capable of challenging teams and service providers;

• an operational referent guaranteeing the security of operations;

• a transverse player capable of uniting teams with different profiles and experience levels.

You have genuine technical authority: when safety conditions or risk management are not met, you are capable of challenging an operation and, if necessary, issuing a NO GO on an operating procedure or intervention.

You will work in close collaboration with the site managers, who retain operational responsibility for their scope.

Your Main Missions

1 - Be the technical referent for critical infrastructures

You will bring your expertise to all Data Center technical infrastructures and be able to understand their interactions and operational impacts.

Your scope includes, but is not limited to:

• HT/BT electrical infrastructures;

• emergency power systems;

• UPS / uninterruptible power supplies;

• generator sets;

• HVAC / climate control infrastructures;

• cooling systems;

• fire protection and safety;

• control systems and associated infrastructures.

You will act as a technical referent for site managers and Operations teams, and be able to challenge various internal or external stakeholders on their choices and practices.

2 - Secure Operations

One of your major responsibilities will be to ensure that operations carried out on critical infrastructures are prepared and executed under the best safety and risk management conditions.

To this end, you will:

• challenge operating procedures (MOP);

• verify the consistency and completeness of procedures;

• identify risks and their potential impacts;

• secure operations before their execution;

• challenge initial analyses and intervention proposals;

• be able to issue a NO GO when an operation does not present the necessary guarantees;

• support site managers in technical decision-making;

• contribute to the implementation of double-checking mechanisms.

You are, in a way, the technical safeguard of the organization, with the goal of securing operations without losing sight of service continuity imperatives.

3 - Structure and Harmonize Practices

One of the major challenges of the role is to contribute to the harmonization of practices across different sites.

Currently, maturity levels and practices can vary from one site to another. Your role will be to contribute to building a common foundation of operational methods and standards.

You will be required to:

• structure operating processes;

• define and harmonize technical standards;

• write and improve procedures and operating methods;

• implement operational workflows;

• monitor their proper application;

• identify discrepancies between sites;

• propose and monitor improvement plans;

• share best practices;

• conduct multisite lessons learned (REX);

• support teams in adopting new standards.

The ability to build and maintain processes will therefore be as important as your technical expertise.

4 - Provide your expertise during critical incidents

In the event of a complex technical incident, you will act as a technical referent for the Facility and Operations teams.

You will be required to:

• technically analyze the incident;

• identify causes and potential impacts;

• provide your expertise to site managers;

• challenge proposed analyses;

• support internal teams and service providers;

• contribute to defining corrective actions;

• participate in incident resolution;

• organize and share lessons learned across the various sites.

Your ability to take a step back, quickly analyze a complex situation, and provide a technically robust response will be essential.

5 - Develop a culture of operational excellence

You will not just define standards: you will support teams in their adoption.

You will be required to:

• train and support teams;

• explain technical and operational requirements;

• improve practices;

• unite around common objectives;

• support change management;

• promote knowledge sharing between sites.

You have a strong capacity for influence and know how to advance projects without necessarily having a direct hierarchical link.

6 - Be the technical point of contact for major clients

You will be able to:

• represent the company on technical matters;

• explain a complex situation or incident;

• present actions taken;

• respond to clients' technical questions;

• provide a structured and credible discourse on infrastructure operation and security issues.

An Organization Under Construction

You will join a newly structured transverse technical expertise hub, bringing together various skills to support operations and projects.

The objective is to create a true community of experts capable of providing their expertise to all sites and collectively advancing operational standards.

You will work daily with:

• site managers;

• Facility and Operations teams;

• project teams;

• technical experts;

• external service providers and partners;

• transverse functions;

• major clients.

The position is therefore particularly transverse and requires a strong ability to create links between the various stakeholders.
