Director of Infrastructure Job Description

A Director of Infrastructure is accountable for the layer of technology that nobody notices until it fails. Routers, switches, firewalls, hypervisors, storage arrays, backup systems, identity directories, cloud landing zones, and the people who operate them all roll up to this one leader. When an application team needs capacity, when a branch office loses connectivity, or when the cloud invoice jumps without warning, the question lands on this desk.

The job falls under computer and information systems managers, and BLS notes that the scope depends on the organization: some of these managers oversee an entire IT department, while others are responsible for a particular area such as infrastructure, support services, or cybersecurity. The infrastructure director is the second case. In a mid-sized company the title can cover everything below the application tier; in a large enterprise it may sit beside separate directors for networks, cloud, or end-user computing.

The work splits into a few recurring modes.

Planning. The director turns business plans into platform plans. A new product launch means compute and network capacity. An acquisition means merging two directories, two WANs, and two sets of vendor contracts. An expiring colocation lease forces a decision about whether to renew, consolidate, or move workloads to a hyperscaler such as AWS, Microsoft Azure, or Google Cloud. Each choice comes with a cost model, a risk register, and a migration sequence.

Running operations. Infrastructure is judged on availability. The director rarely types the fix during an outage, but sets the escalation path, the change-control rules, and the on-call structure that decide how quickly a fault gets found. After a serious incident, the director chairs the review and makes sure the corrective work actually gets scheduled rather than parked.

Managing money and vendors. BLS lists assessing the costs and benefits of new projects and negotiating with and monitoring vendors among the core duties of this occupation. For an infrastructure leader that means hardware refresh cycles, cloud commitments and reserved capacity, enterprise license agreements, support contracts, and managed service deals. A director who can explain a variance to the CFO in plain terms earns room to make bigger bets.

Protecting the estate. BLS also lists establishing processes to detect, prevent, and mitigate IT security threats among the occupation's duties. Security strategy may sit with a CISO, but the infrastructure team holds the keys: patching, hardening, segmentation, privileged access, and backups that ransomware cannot reach. The director makes sure those controls exist in practice and not only in policy documents.

Leading people. The team mixes network engineers, systems administrators, cloud and platform engineers, storage specialists, and operations staff. Keeping senior engineers engaged, building a bench for succession, and moving routine work into automation so people can focus on harder problems are central parts of the job, not side tasks.

Day to day, the calendar is a blend of architecture reviews, vendor calls, budget meetings, incident follow-ups, and one-on-ones. The common thread is translation: turning technical risk into business language for executives, and turning business priorities into clear work for engineers.

Education. BLS says computer and information systems managers typically need a bachelor's degree in computer science or information technology, plus related work experience, to enter the occupation. Degrees in management information systems or engineering technologies also fit, since they pair technical coursework with business classes. Some organizations require or prefer a graduate degree in computer science, information technology, or business administration, and an MBA can help a director who expects to spend more time with finance than with engineers.

Experience. This is not an entry-level management job. BLS notes that CTOs, IT directors, and other senior-level managers usually need many years and extensive experience in the IT field before they are considered, and that some employers want experience in their own industry. A hospital, for example, may look for someone who already understands clinical systems and the uptime they demand.

A typical path runs through hands-on infrastructure work first: systems administration, network engineering, storage, or cloud engineering. From there, people usually move into a team lead or infrastructure manager role, take ownership of a budget and a vendor portfolio, and lead at least one large program such as a data center exit, a cloud migration, or a network redesign. As general guidance, plan on a decade or more of progressively senior work before a director title, with a few of those years spent managing managers. From director, the usual next steps are VP of infrastructure, VP of IT operations, or CIO at a smaller organization.

Technical depth worth having:

• One major public cloud at architecture depth: accounts and landing zones, identity, networking, storage tiers, and cost controls
• Enterprise networking: WAN and SD-WAN design, BGP, segmentation, and zero trust network access
• Virtualization and containers: hypervisor platforms, Kubernetes, and the licensing terms attached to each
• Automation: Terraform or a similar infrastructure-as-code tool, configuration management, and CI/CD pipelines for infrastructure changes
• Observability and IT service management: monitoring, logging, alert routing, change control, and a clean configuration management database

Credentials and training worth pursuing:

• AWS Certified Solutions Architect – Professional (Amazon Web Services)
• Microsoft Certified: Azure Solutions Architect Expert (Microsoft)
• CISSP (ISC2), useful where infrastructure and security teams share ownership of controls
• ITIL Managing Professional (PeopleCert), for shops that run formal service management
• Project Management Professional, PMP (Project Management Institute)
• FinOps Certified Practitioner (FinOps Foundation), for directors who own cloud spend

Qualities that separate strong candidates. BLS highlights analytical, communication, decision-making, leadership, and problem-solving skills for this occupation, along with real computer expertise. In practice, the deciding factor is often communication: the ability to explain a capacity risk or a contract trade-off to executives who do not share the vocabulary, and to give engineers instructions clear enough that work gets done right the first time.

The federal projections are strong. BLS expects employment of computer and information systems managers to grow 16 percent from 2025 to 2035, much faster than the average for all occupations, from about 685,800 jobs in 2025. The agency projects about 53,500 openings each year over the decade, many of them from the need to replace workers who transfer to different occupations or exit the labor force, such as to retire. BLS ties the growth to businesses ramping up IT infrastructure such as cloud computing, cybersecurity, digital platforms, and artificial intelligence.

Those managers work across the economy. BLS lists computer systems design and related services as the largest employer, at 19% of jobs, followed by finance and insurance and the information sector at 13% each, management of companies and enterprises at 10%, and manufacturing at 6%.

Several forces shape what the job looks like now.

Power has become an infrastructure constraint. A Department of Energy announcement in December 2024 of a report produced by Lawrence Berkeley National Laboratory said that data centers consumed about 4.4% of total U.S. electricity in 2023 and are expected to consume approximately 6.7 to 12% by 2028. For directors who own facilities or colocation contracts, power availability and density now belong in capacity planning alongside rack space and network ports.

Cost control dominates the agenda. In the Uptime Institute Global Data Center Survey 2025, which drew responses from more than 800 data center owners and operators worldwide, cost issues remained the top concern for digital infrastructure management teams, and concerns about forecasting future capacity requirements grew significantly. The FinOps Foundation's State of FinOps 2026 report, a survey of 1,192 respondents from the global FinOps community, found that 98% of respondents said their FinOps teams now manage AI spend and 48% manage data center spend; the foundation says its mission has evolved from "cost of cloud" to "value of technology." Those programs depend on usage data that infrastructure teams produce.

Licensing shifts can force platform decisions. After Broadcom bought VMware, it stopped selling VMware perpetual licenses and began requiring subscriptions, according to Ars Technica. The publication reported that Broadcom also bundled VMware's products into a smaller number of SKUs, resulting in higher costs for some customers. For an infrastructure director, the hypervisor contract becomes a decision point: renew, renegotiate, or study a migration.

Operations leadership is in short supply. The same Uptime survey ranked operations management as the job category with the most serious skills gap in 2025, cited by 39% of operators. Nearly half (46%) of operators reported difficulty finding qualified candidates, and more than one in three (37%) struggled to retain staff, and most operators with retention problems said workers were being hired away by competitors rather than leaving the industry.

Resilience still gets measured. Uptime's 2025 survey found that impactful data center outages are gradually becoming less frequent, but one in 10 outages still causes serious or severe disruption. That finding keeps disaster recovery testing, redundant power and network paths, and disciplined change control on the director's list, even in shops that have moved much of their work to public cloud.

Dear Hiring Committee,

I am applying for the Director of Infrastructure position with your health system. For the past several years I have led infrastructure and operations at a regional insurer, where my team runs the networks, data center, private cloud, and public cloud accounts behind every claims and member system. I am drawn to your role because it combines a hospital network's uptime demands with a hybrid estate that is still taking shape, which is exactly the kind of problem I like to own.

When I took over my current team, the estate had grown by accretion. Two hypervisor platforms, overlapping monitoring tools, and a backup design nobody had tested end to end. I started with an honest inventory and a recovery test that failed in instructive ways. Over the following year we consolidated onto one virtualization platform, rebuilt backups so they were isolated from production credentials, and moved our change process from email approvals to tracked, peer-reviewed infrastructure code. The next recovery test passed, and the one after that passed faster.

I also spend a large share of my time on money and contracts. I rebuilt our infrastructure budget around unit costs that finance could follow, renegotiated our colocation agreement before renewal instead of after, and set up a monthly cloud spend review with application owners so surprises became conversations.

People are the part of the job I care about most. I have hired and promoted engineers into lead roles, created an on-call rotation that people no longer dread, and made post-incident reviews about systems rather than blame.

I would welcome the chance to talk about how I would approach your first year: stabilizing operations, clarifying ownership, and building a roadmap your clinical and finance leaders can both support.

Sincerely, Jordan Ellison
