The title covers several different jobs: facilities, electrical, mechanical, controls, network, design (MEP), commissioning, and operations engineers. Design roles usually need an engineering degree and often a PE license; operations and commissioning roles are often filled by experienced technicians. Key takeaways - Read the duties, not the title. "Data center engineer jobs" range from IT networking to switchgear design to running a shift. - Design engineers follow the degree and Professional Engineer (PE) path. Facilities, operations, and commissioning engineers often come up from the trades. - There is no single data center engineer certification. Credentials depend on the specialty, from the PE license to BICSI, Uptime Institute, and vendor certifications. - BLS has no data center engineer category; comparable occupations such as electrical engineers had a May 2025 median annual wage of $120,630. ## What is a data center engineer? A data center engineer is anyone whose job is the engineering of a data center's infrastructure: designing it, proving it works, or keeping it running. Some work for the operator on site, some for engineering firms and contractors, and some for equipment manufacturers. The title is used loosely. "Data center infrastructure engineer" can mean the facility side (power and cooling) at one company and servers, storage, and virtualization at another. In facilities, "engineer" is also a traditional trade title, so a "data center facilities engineer" may be a senior technician rather than a degreed engineer. ## Types of data center engineers compared The table below compares the eight roles you will see most often. Credentials listed are ones people in each role commonly pursue, not universal requirements. **Data center engineer roles: focus, background, and credentials** | Role | Main focus | Typical background | Credentials people pursue | | --- | --- | --- | --- | | Facilities / critical facilities engineer | Operating and maintaining power, cooling, and life safety on site | Electrician, HVAC, military, or building engineering | Trade licenses, EPA Section 608, operations credentials | | Electrical engineer | Power system design, studies, and specifications | Electrical engineering degree | PE license; Uptime Accredited Tier Designer | | Mechanical engineer | Cooling plant, airflow, and liquid cooling design | Mechanical engineering degree | PE license; Uptime Accredited Tier Designer | | Controls / BMS engineer | BMS and EPMS design, sequences, integration, alarms | Controls technician, EE, ME, or IT | Manufacturer training on specific control platforms | | Network engineer | Switching fabrics, routing, and connectivity | IT or computer science | Vendor certifications such as Cisco CCNP or CCIE Data Center | | Design / MEP engineer | Integrated mechanical, electrical, and plumbing design for new builds | Engineering degree, consulting firm experience | PE license; BICSI RCDD or DCDC | | Commissioning engineer | Testing systems from factory witness to integrated systems test | EE or ME, or senior technician or electrician | Commissioning and electrical testing credentials | | Operations engineer | Site reliability: MOP review, incidents, capacity, performance | Senior technician or engineer | Uptime Accredited Operations Specialist and similar | ## Data center engineer roles in detail Each role below includes what it involves and the usual way in. ### Facilities engineer (critical facilities engineer) The hands-on operations role: rounds, maintenance, switching under procedures, and alarm response across electrical, mechanical, and controls systems. **How to get there:** a trade background plus mission-critical experience. Our [critical facilities technician guide](https://datacentertraining.us/careers/critical-facilities-technician.html) covers this path in depth. ### Data center electrical engineer Designs the power system: one-line diagrams, equipment sizing, redundancy topology, short-circuit and coordination studies, and arc flash studies. On operating sites, electrical engineers own the power system's performance and approve risky switching. **How to get there:** an electrical engineering degree, then experience at an engineering firm, contractor, or operator. Data center electrical engineer jobs at design firms usually expect progress toward a PE license. ### Data center mechanical engineer Designs and analyzes cooling: chiller plants, air handling, containment, economizers, and liquid cooling loops. **How to get there:** a mechanical engineering degree; BLS notes the PE license is not needed for entry-level mechanical engineers but can be earned later. HVAC technicians who want this work should read our [data center HVAC technician guide](https://datacentertraining.us/careers/data-center-hvac-technician.html). ### Data center controls engineer Designs and maintains the BMS and electrical power monitoring system (EPMS): points lists, sequences of operation, alarm philosophy, network and cybersecurity for building systems. **How to get there:** often from controls technician roles or HVAC controls contractors; learn common protocols such as BACnet and Modbus. [Monitoring, Automation & BMS Systems](https://datacentertraining.us/courses/monitoring-automation-bms-systems.html) is a solid starting point. ### Data center network engineer Builds and runs the data center network: spine-leaf switching fabrics, routing, load balancing, and automation. This is an IT role, but good network engineers understand rack power and cabling limits. **How to get there:** IT or computer science background, network operations experience, and vendor certifications. ### Data center design engineer (MEP) Coordinates mechanical, electrical, and plumbing design for new facilities, working with architects and the owner's standards. **How to get there:** an engineering degree, consulting firm experience, and a PE license for senior roles. [Data Center Design Fundamentals](https://datacentertraining.us/courses/data-center-design-fundamentals.html) and [Tier Infrastructure Fundamentals](https://datacentertraining.us/courses/tier-infrastructure-fundamentals.html) cover the vocabulary design reviews use. ### Data center commissioning engineer Proves new systems work before handover, through the commissioning levels most of the industry uses: L1 factory witness testing, L2 delivery and installation inspection, L3 pre-functional checks and start-up, L4 functional performance testing, and L5 integrated systems testing. **How to get there:** engineers, senior electricians, and controls technicians all move in; see [Infrastructure Commissioning & Startup](https://datacentertraining.us/courses/infrastructure-commissioning-startup.html). ### Data center operations engineer Owns reliability for a running site or region: reviews MOPs, leads incident investigations, tracks capacity, and improves procedures. **How to get there:** usually from senior technician or facilities engineer roles, or from design engineering with an interest in operations. ## MEP design engineer for AI data centers MEP design for AI data centers is the same discipline under heavier loads. GPU racks draw far more power than typical enterprise racks, so electrical designers plan larger feeders, more transformation and switchgear per hall, and higher-amperage rack power. Mechanical designers plan liquid cooling: facility water loops, coolant distribution units, and the controls and leak detection that go with them, alongside air cooling for the remaining heat. Coordination is harder because both systems grow at once. The [AI data centers guide](https://datacentertraining.us/learn/ai-data-centers.html) explains the density problem, and [AI data center jobs](https://datacentertraining.us/careers/ai-data-center-jobs.html) covers who is hiring. ## Data center engineer salary: BLS benchmarks BLS does not publish pay for data center engineers as a group. These are the closest BLS occupations, all median annual wages for May 2025: **BLS median annual wages for comparable engineering occupations, May 2025** | BLS occupation | Median annual wage | Closest data center roles | | --- | --- | --- | | [Computer network architects](https://www.bls.gov/ooh/computer-and-information-technology/computer-network-architects.htm) | $134,050 | Senior network engineer | | [Electrical engineers](https://www.bls.gov/ooh/architecture-and-engineering/electrical-and-electronics-engineers.htm) | $120,630 | Electrical, design, commissioning engineer | | [Mechanical engineers](https://www.bls.gov/ooh/architecture-and-engineering/mechanical-engineers.htm) | $104,110 | Mechanical, design, commissioning engineer | | [Network and computer systems administrators](https://www.bls.gov/ooh/computer-and-information-technology/network-and-computer-systems-administrators.htm) | $99,130 | Network or infrastructure engineer | Facilities and operations engineers are closer to the skilled trades; see the BLS comparables in our [critical facilities technician](https://datacentertraining.us/careers/critical-facilities-technician.html) guide.

People build credentials that match their specialty. Commonly pursued options, described by their issuers: - **Professional Engineer (PE) license:** issued by state licensing boards. NCEES develops the Fundamentals of Engineering (FE) exam, generally the first step, and the PE exam, typically taken after several years of experience. - **BICSI:** the Registered Communications Distribution Designer (RCDD) for ICT infrastructure design and the Data Center Design Consultant (DCDC) for data center design. - **Uptime Institute:** Accredited Tier Designer (ATD) for engineers designing to its Tier Standard, Accredited Tier Specialist (ATS), and Accredited Operations Specialist (AOS) for people who run critical facilities. - **Cisco:** CCNP Data Center and CCIE Data Center for network engineers. - **NETA:** technician certification from the InterNational Electrical Testing Association, relevant to electrical testing and commissioning. Check each issuer for current eligibility, format, and cost. Data Center Training is not affiliated with these organizations. Our [data center certifications guide](https://datacentertraining.us/careers/data-center-certifications.html) compares more options. Our own courses award certificates of completion and build the systems knowledge these credentials assume. ## How to become a data center engineer 1. ### Pick your lane Decide between design (degree and PE path), IT and network (vendor certification path), or facilities and operations (trade and experience path). 2. ### Build the foundation Earn the relevant degree, or finish a trade apprenticeship and license if you are coming up through operations. 3. ### Get data center project time Ask for data center projects at your firm, join a contractor or commissioning agent on a build, or take a technician role at an operating site. 4. ### Learn the shared language Redundancy (N+1, 2N), Tier concepts, ANSI/TIA-942, commissioning levels, and how MOPs control risk. Every type of data center engineer uses them. 5. ### Add the credentials your specialty values Start the FE exam early if you are on the PE path; add BICSI, Uptime, or vendor certifications as your role calls for them. ## Data center engineer resume tips - Lead with the systems you worked on and their scale: megawatts, tons of cooling, number of halls, or switches deployed. - Name your role in each phase: design, construction, commissioning level, or operations. - Show reliability results, such as maintenance completed without customer impact or issues found during testing. - List licenses and certifications with the issuing organization. - Match the posting's words, since "infrastructure," "facilities," and "operations" engineer can mean different jobs.

For design roles such as electrical, mechanical, and MEP design engineer, yes: employers expect an engineering degree, and senior roles often need a Professional Engineer license. Facilities, operations, and commissioning engineer roles are different. Many are filled by experienced electricians, HVAC technicians, and military technicians without engineering degrees. ### What certification is best for a data center engineer? It depends on the specialty. Design engineers pursue the PE license and design credentials such as BICSI's RCDD or DCDC or Uptime Institute's Accredited Tier Designer. Network engineers pursue vendor certifications such as Cisco's CCNP Data Center. Operations engineers look at operations-focused credentials. There is no single license called data center engineer. ### Is a data center engineer the same as a data center network engineer? Not always. Some employers use data center engineer for network or IT infrastructure roles that build switching fabrics, servers, and storage. Others use it for facilities roles that run power and cooling. Read the duties in the posting: routing, switching, and automation point to IT; UPS, chillers, and MOPs point to facilities. ### What does a data center commissioning engineer do? A commissioning engineer proves that new power, cooling, and controls systems work as designed before the owner accepts them. They write test scripts, witness factory and site tests, run functional and integrated systems tests with load banks, track issues to closure, and assemble turnover documentation. The role involves frequent travel to construction sites. ### Do data center engineers need a PE license? Engineers who sign and seal design drawings need a Professional Engineer license from the state where the project is located. Licensure typically requires an accredited degree, passing the NCEES Fundamentals of Engineering exam, several years of experience, and passing the PE exam. Operations, network, and commissioning engineers often work without one. ## Sources - Electrical and Electronics Engineers; Mechanical Engineers; Computer Network Architects; Network and Computer Systems Administrators.
