As hyperscale, enterprise, and AI-driven data center development continues to accelerate, demand for experienced commissioning engineers has outpaced available talent in many markets.

Commissioning sits at a critical point in the data center lifecycle. Before a facility can reliably support live workloads, teams need to know that its electrical, mechanical, controls, and other critical systems will operate as designed, both individually and together.

That requires professionals who understand far more than a single system or engineering discipline. Experienced commissioning engineers bring technical knowledge, testing expertise, an understanding of system dependencies, and the ability to coordinate across multiple teams.

As data center development grows in scale and complexity, that combination of experience can be difficult to find.

What Is a Commissioning Engineer and Why Do They Matter?

Commissioning engineers help oversee the transition from construction to operation by verifying that critical systems perform according to the project’s design intent and operational requirements.

In a data center environment, that can include electrical distribution, backup power, cooling, building management systems, alarms, controls, and other interconnected infrastructure.

Their work may involve reviewing designs, inspecting installations, developing and executing test procedures, documenting results, identifying deficiencies, verifying corrective work, and supporting integrated systems testing.

The goal is not simply to confirm that individual pieces of equipment turn on. Commissioning helps determine whether systems will perform together under expected operating conditions, including failure scenarios and redundancy requirements.

That makes experienced commissioning professionals an important part of bringing mission critical infrastructure online.

Why Is There a Talent Gap in Data Center Commissioning?

The challenge is not simply finding engineers. It is finding professionals with the combination of experience required for a mission critical commissioning environment.

Several factors contribute to the limited talent pool:

• Commissioning requires cross-disciplinary knowledge. Professionals may need experience across electrical, mechanical, controls, and operational systems, limiting the number of candidates who can step directly into senior commissioning roles.

• Data center systems are becoming more complex. Higher-density computing, evolving cooling technologies, sophisticated controls, and increasingly interconnected infrastructure create additional testing requirements.

• Experienced professionals take time to develop. Senior commissioning expertise typically comes from hands-on exposure to complex projects and systems. It cannot be developed through classroom training alone.

• Geography can restrict an already limited talent pool. Data center projects may require significant onsite work, travel, or relocation, while experienced candidates can have opportunities across multiple markets.

• Other industries compete for similar skills. Semiconductor, advanced manufacturing, healthcare, energy, and other mission critical environments need professionals with overlapping electrical, mechanical, controls, and commissioning expertise.

These factors become more significant as multiple data center projects compete for experienced professionals at the same time.

What Is Driving Demand for Commissioning Engineers?

Data center construction itself is an obvious driver, but the type of infrastructure being built also matters.

More Complex Power and Cooling Systems

Higher-density computing environments can create new power and thermal management requirements. Traditional air cooling remains important, while chilled water systems, in-row cooling, direct-to-chip liquid cooling, and other approaches can add additional complexity depending on the facility.

Commissioning teams must understand how these systems are intended to perform and how they interact with the rest of the facility.

Larger and More Complex Developments

Hyperscale campuses and large data center programs can involve multiple buildings, phases, contractors, vendors, and commissioning milestones.

Organizations need commissioning processes that can remain consistent as projects expand without overlooking site-specific requirements.

Greater Systems Integration

Power, cooling, building management, monitoring, alarms, and controls increasingly operate as interconnected systems.

Commissioning therefore extends beyond testing individual components. Teams must evaluate how systems communicate and respond together, particularly during equipment failures, failovers, and other abnormal conditions.

Growing Operational Expectations

For mission critical facilities, reliability is central to the business case.

That places additional importance on testing redundancy, sequence of operations, alarms, controls, and recovery scenarios before the facility moves into normal operation.

How Commissioning Staffing Challenges Affect Data Center Projects

When the appropriate commissioning resources are unavailable at the right stage of a project, the effects can extend beyond the commissioning team.

Testing windows may become harder to coordinate. Deficiencies may take longer to identify or resolve. Construction and operations teams can face additional pressure as turnover approaches.

There is also a knowledge-transfer component.

Commissioning creates an opportunity for facility operators to understand how systems behave before assuming responsibility for the environment. If that process is rushed or inadequately staffed, operations teams may enter the handoff with less firsthand knowledge of the facility’s systems and known issues.

For employers, commissioning workforce planning should therefore begin well before testing is scheduled to start.

Strategies to Address the Commissioning Talent Gap

The following practical strategies can help data center organizations of all sizes improve commissioning readiness and reduce staffing risk.

1. Expand the Talent Pipeline

Organizations cannot solve a limited senior talent pool simply by competing harder for the same experienced candidates.

Long-term workforce planning should include developing the next generation of commissioning professionals.

That could include partnerships with engineering programs and technical schools, internships, apprenticeships, and rotational programs that expose early-career professionals to electrical, mechanical, controls, and facility operations.

Employers can also evaluate professionals from adjacent mission critical industries whose experience may transfer to data center commissioning.

2. Support Relevant Commissioning Certifications

Certifications do not replace hands-on data center experience, but they can support professional development and demonstrate knowledge of established commissioning principles.

Depending on the position, relevant credentials may include:

• Certified Commissioning Professional (CCP)

• ACG Certified Commissioning Authority (CxA)

• Building Commissioning Professional (BCxP)

Employers should evaluate certifications alongside actual project experience, technical knowledge, and familiarity with mission critical environments rather than treating a credential as a substitute for those qualifications.

3. Build Repeatable Commissioning Playbooks

Standardized processes can help organizations make better use of limited commissioning resources.

Playbooks can document expectations for design reviews, pre-functional checks, functional testing, integrated systems testing, deficiency tracking, acceptance criteria, and turnover.

Test plans can then be adapted to the specific equipment, redundancy strategy, and operational requirements of each facility.

Standardization also helps preserve institutional knowledge when experienced professionals move between projects.

4. Invest in Training and Mentorship

Senior commissioning professionals can play an important role in developing less-experienced engineers.

Structured mentorship can include field shadowing, test development, design reviews, deficiency resolution, and participation in integrated systems testing.

Rather than limiting junior professionals to observation, organizations can gradually give them responsibility under the guidance of experienced commissioning leaders.

Over time, this helps create a deeper internal talent pipeline.

5. Use External Expertise Strategically

Not every organization needs enough permanent commissioning staff to cover peak demand across every stage of every project.

Engage trusted commissioning partners or specialized staffing resources during peak build phases, complex retrofits, major expansions, or periods when internal teams lack specific expertise.

External professionals can supplement internal resources, provide specialized technical knowledge, and help organizations address temporary increases in commissioning workload without requiring every need to become a permanent position.

The key is to engage those resources early enough to understand project requirements, milestones, acceptance criteria, and testing windows.

6. Prioritize Knowledge Transfer

Commissioning should not operate in isolation from the teams that will ultimately run the facility.

Facilities, operations, engineering, IT, controls, and other relevant stakeholders should have appropriate involvement throughout the commissioning process.

Organizations should also document lessons learned, recurring deficiencies, testing outcomes, and system-specific knowledge so insights from one project can inform future facilities.

What Does the Data Center Commissioning Process Look Like?

Although the exact process varies by project, data center commissioning generally progresses through several stages.

Design Review and Risk Assessment

Commissioning involvement can begin before construction is complete.

Teams review design documents, sequences of operation, equipment requirements, redundancy strategies, and integration points to identify potential issues before they become more expensive or difficult to correct.

Pre-Functional Verification

Before functional testing begins, teams verify that equipment and systems have been installed appropriately and are ready for testing.

This can include checking installation, wiring, labeling, documentation, controls, and safety requirements.

Functional Performance Testing

Individual systems are tested against established requirements and sequences of operation.

For a data center, this can involve electrical distribution, generators, UPS systems, cooling equipment, controls, alarms, and other critical infrastructure.

Integrated Systems Testing

This is where cross-disciplinary commissioning experience becomes particularly important.

Teams evaluate how multiple systems respond together during realistic operating and failure scenarios. That may include utility loss, generator transitions, equipment failures, redundancy events, and other scenarios based on the facility’s design.

Acceptance and Turnover

Commissioning results, open items, test documentation, and other required materials are compiled as the project moves toward acceptance.

Operations teams should also receive the documentation and knowledge needed to understand the facility they are inheriting.

Measuring Commissioning Readiness

Organizations can use project-specific measures to understand whether commissioning is progressing as expected.

Depending on the facility and project requirements, those measures might include:

• Completion of planned commissioning activities

• Open and resolved deficiencies

• Retesting requirements

• Schedule adherence

• Readiness for integrated systems testing

• Documentation completion

• Operator training and turnover progress

The objective is not simply to create another dashboard. Measurement should give project leaders visibility into issues that could affect testing, turnover, or operational readiness.

Building a More Sustainable Commissioning Workforce

For employers facing commissioning talent challenges, the solution is unlikely to be a single hiring initiative.

Organizations should first determine which commissioning capabilities they need internally, which can be developed over time, and where external expertise makes more sense.

From there, workforce planning can include several parallel efforts: identifying experienced talent earlier, developing junior professionals, considering candidates from adjacent mission critical industries, creating repeatable processes, and using contract or project-based professionals when specialized expertise or additional capacity is required.

The earlier those decisions are made, the more options employers have.

Preparing for What’s Next

Data center growth is increasing demand for professionals who understand how complex electrical, mechanical, controls, and operational systems work together.

Commissioning engineers sit at the center of that challenge.

Building a stronger commissioning function requires more than filling an open position when a project reaches its testing phase. It requires workforce planning, talent development, consistent processes, and access to specialized expertise when project demands exceed internal capacity.
