When and how should you hire the maintenance team?
One of the most strategic decisions in data center management is determining when to bring on the maintenance manager and their team, and how to properly assemble that team. Although this step is often deferred to the final stages, hiring the operations team early can prevent costly errors and significantly improve long-term performance.
In this guide, we address some of the most common questions on this topic: when to hire, how many people are needed, whether to use in-house or external staff, and what qualities ideal candidates should possess.
When should I hire the maintenance manager and their team?
The recommendation is clear: do it as soon as possible.
Many organizations wait until the data center is about to begin operations before considering the maintenance team. However, involving them from the initial stages offers crucial benefits:
🔹 During the design phase
The maintenance team can provide an operational perspective that is often overlooked in technical planning. Participation at this stage allows for the anticipation of actual operational, accessibility, and safety needs, ensuring the design promotes long-term efficiency.
🔹 During construction
At this stage, there is often a tendency to seek shortcuts or solutions that “work for now” but complicate future maintenance. The maintenance team can act as a guardian of operational best practices, overseeing construction decisions to ensure they do not compromise functionality.
🔹 During operations
Once the data center is active, the learning curve begins. Having staff trained and familiar with the site prior to startup reduces operational errors and enables a smoother, safer transition.
How much staff do I need?
There is no magic number, but these are the key factors for determining the size of your team:
🛠️ Maintenance program
It must be based on the recommendations of each piece of equipment’s manufacturer, as well as the conditions and criticality of the data center. A sound plan requires sufficient personnel to execute it without jeopardizing operations.
🔄 Daily operation
Operations do not stop; therefore, you need sufficient staff and schedule coverage to ensure monitoring, incident response, and the completion of daily routines.
🔧 Internal and/or external maintenance
Some tasks can be performed by external providers, but others must remain under internal control. The key lies in knowing how many man-hours are required for each activity and strategically deciding how to cover them.
In-house or outsourced staff?
It depends on your business model, budget, and desired level of control. Here is a summary of the advantages:
- In-house: Greater control, continuity, site knowledge, and immediate responsiveness. Ideal for critical 24/7 facilities.
- Outsourced: Provides specialized expertise in specific areas, can reduce fixed costs, and facilitates the management of specific tasks.
✅ The best option is usually a hybrid model, featuring an in-house core team and certified external providers for specialized or high-risk tasks.
What characteristics should maintenance personnel possess?
Beyond the number of people, the quality and profile of your team will make the difference in data center operations. Ensure they have:
✔️ Technical capacity
Proficiency in electrical infrastructure, HVAC, backup systems, monitoring, safety standards, and operational protocols. Technical certifications are a significant value-add.
✔️ Eagerness to learn
Technology is constantly changing. Staff must be willing to update their skills, undergo training, and adapt to new systems with agility.
✔️ Teamwork
Data center operations involve interdisciplinary work. It is crucial that the team be able to communicate and collaborate effectively with other departments and vendors.
Conclusion: Do not underestimate the importance of the operational team.
Hiring the maintenance team from the outset, with a clear and strategic approach, is not an expense; it is an investment in operational continuity and risk prevention.
