6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Service Availability

Uptime of critical Tier 1 business services (e.g., core applications, network connectivity).

Target · Achieve 99.99% ('four nines') availability for Tier 1 services.

Maintaining 99.99% uptime means less than 5 minutes of unplanned downtime per month for our main customer-facing platform. If it dips below, we'll be asking why.

Infrastructure Total Cost of Ownership (TCO)

Overall expenditure on cloud resources, hardware, software licences, and operational staff.

Target · Reduce TCO by 5-10% annually through optimisation and strategic vendor management.

Identifying and decommissioning unused cloud resources, renegotiating a major software licence, or shifting workloads to more cost-effective platforms to save £150K this financial year.

Disaster Recovery (DR) Test Success Rate

Successful completion of annual DR tests, demonstrating the ability to recover critical services within defined RTO/RPO.

Target · 100% successful annual DR test with zero data loss for Tier 1 applications.

Successfully failing over our entire production environment to a secondary region and recovering all critical services within 4 hours, without losing any customer data, as per our RTO/RPO targets.

Mean Time To Recovery (MTTR)

Average time taken to restore service after a P1 or P2 incident.

Target · Maintain MTTR for P1 incidents below 30 minutes, and P2 incidents below 2 hours.

If we have a major outage, getting the service back online in 25 minutes instead of 45 minutes. This means quick, effective troubleshooting and clear incident management.

Team Performance & Development

How well your team is performing, growing, and staying engaged.

You'll see this in low team attrition (below 10%), high scores on employee engagement surveys (>85%), and individual engineers taking on more complex tasks. We'll also look at how many professional development goals are met across your team.

Stakeholder Trust & Collaboration

How effectively you work with other teams and how much they trust your judgment.

Other department leads will proactively come to you for infrastructure advice on new projects. You'll be invited to early planning meetings, and your input will be genuinely valued. We'll also look at feedback from regular cross-functional project retrospectives.

Proactive Risk Management

Identifying and mitigating potential infrastructure risks before they become problems.

This means you're presenting clear risk assessments to the Director, implementing solutions like improved monitoring or redundancy, and reducing the number of unexpected 'P1' incidents. We'll see fewer surprises and more planned work.

Documentation & Knowledge Sharing

Ensuring our infrastructure knowledge is well-documented and accessible.

Your team's runbooks will be up-to-date and actually used. New team members will be able to get up to speed quickly because the documentation is clear. We'll also see evidence of regular knowledge-sharing sessions within your team and across departments.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy

Solving Complex Technical Puzzles

You get a real buzz from figuring out why a distributed system is failing, or designing a resilient network architecture that can handle massive traffic spikes. It's the challenge of making disparate systems work together seamlessly.

Spending a few hours deep-diving into cloud logs and network traces to diagnose a tricky latency issue that's been baffling the team, and then coming up with a robust fix.

Building and Growing a High-Performing Team

You genuinely enjoy mentoring engineers, seeing them develop new skills, and empowering them to take ownership. You get satisfaction from creating a cohesive team that delivers reliable infrastructure.

Helping a junior engineer troubleshoot a difficult problem, then giving them the lead on a new project, and seeing them absolutely smash it.

Ensuring Business Continuity and Reliability

The thought of a system going down keeps you up at night (in a good way, mostly). You're driven by the responsibility of keeping the business running and knowing your work directly prevents costly outages.

Successfully leading a major DR test, proving that our systems can withstand a catastrophic failure and knowing the business is protected.

What frustrates people

The 3 AM Outage Call: Getting paged for a critical failure right after you've finally fallen asleep, knowing your next 4 hours will be a high-stress firefight.
Shadow IT: Discovering a department has spun up a critical business process on a cloud service using a credit card, completely outside of your security, backup, and monitoring standards.
"It's a Network Problem": Spending hours proving the network is fine, only to have the developer discover a bug in their application code was the real issue all along.
Budget Realities vs. Best Practices: Knowing you need to replace aging SANs or firewalls but being told there's no budget, forcing you to accept risks you're uncomfortable with.
Inheriting Technical Debt: Taking over a new system and finding it's a house of cards built with no documentation, no automation, and a dozen single points of failure.
The Cost Center Stigma: Constantly having to justify your existence and budget, while being seen as a blocker to innovation rather than the enabler of it.

What this role does not give you

A quiet, uninterrupted work environment where you can focus solely on deep technical work.
A role where you won't have to deal with people issues or challenging team dynamics.
The luxury of always implementing 'perfect' solutions without budget or time constraints.
A guarantee that every project you start will see the light of day exactly as planned.

8Who you work with

This role directly impacts the entire organisation's ability to operate. Your decisions on infrastructure design, resilience, and cost directly affect system uptime, application performance, and our overall security posture. Get it right, and the business runs smoothly, efficiently, and securely. Get it wrong, and we're looking at significant downtime, security breaches, or spiralling costs. You're essentially the guardian of our digital foundations.

9What you need before you start

Not a wish list. The things you would be expected to already have.

Extensive experience (8+ years) as a Senior Infrastructure Engineer or Lead Engineer, with a proven track record of designing and implementing complex infrastructure solutions.
Demonstrable experience leading technical projects from conception to completion, including managing timelines, budgets, and technical risks.
Prior experience managing or mentoring junior engineers, with a clear understanding of what it takes to develop a team.
Strong understanding of financial management principles as they apply to IT infrastructure, including budgeting, forecasting, and cost optimisation.
Proven ability to manage critical incidents, including leading technical teams through resolution and communicating effectively with senior stakeholders.
A solid grasp of at least two major cloud platforms (AWS, Azure, or GCP) at an architectural level, not just operational.

10What to practise next

Where the job is going, and what to do about it starting this week.

Platform Engineering & Developer Experience

As businesses move faster, developers need self-service tools and streamlined workflows to deploy and manage their applications. Infrastructure managers will need to shift from simply providing infrastructure to building 'platforms' that enhance developer productivity and experience.

Internal Developer Portals · Golden Paths · Self-Service Infrastructure · Paved Roads

This quarter: Talk to your development leads about their biggest pain points in deploying and managing applications.
Next quarter: Research common platform engineering tools and frameworks (e.g., Backstage, Crossplane).
Month 6: Identify one 'golden path' for a new application type and work with a dev team to prototype a self-service deployment.
Month 9: Start measuring developer satisfaction and deployment velocity to quantify the impact of platform initiatives.

Quick win: Implement a simple 'template' for a common infrastructure component (e.g., a new database instance) that developers can provision with minimal input, using your existing IaC tools.

Advanced Network Programmability & SASE

Traditional network management is too slow and complex for dynamic cloud environments. Software-Defined Networking (SDN) and Secure Access Service Edge (SASE) are becoming critical for agile, secure, and performant connectivity, especially with distributed workforces.

Software-Defined Wide Area Network (SD-WAN) · Network as Code · Zero Trust Network Access (ZTNA) · Cloud-Native Networking

This quarter: Familiarise yourself with the core concepts of SASE and ZTNA through online courses or webinars.
Next quarter: Evaluate current network architecture against SASE principles, identifying gaps and opportunities.
Month 6: Work with your network engineers to identify one manual network configuration task that can be automated with IaC.
Month 9: Begin discussions with potential SASE vendors or evaluate existing cloud network services for enhanced security and performance.

Quick win: Identify a small, non-critical network configuration change that can be managed entirely through Terraform or Ansible. Get your team comfortable with network as code.

11Staying current once you are in

What people here do to keep up

Regularly attend industry conferences (e.g., AWS re:Invent, Microsoft Ignite, KubeCon) to stay current with the latest trends and network with peers.
Participate in online communities and forums focused on cloud infrastructure, DevOps, and SRE to share knowledge and learn from others' experiences.
Take advanced courses or specialisations in areas like advanced networking, cyber security architecture, or FinOps to deepen your expertise.
Seek out opportunities to mentor junior colleagues, as teaching is often the best way to solidify your own understanding and develop leadership skills.
Read books and articles from thought leaders in infrastructure, SRE, and cloud strategy to broaden your perspective beyond day-to-day operations.

What's rising in its place

This is where the work is heading, and the higher pay with it. Get fluent here and the shift stops being a threat and starts being your edge.

AI-Driven Operations (AIOps) & Predictive Analytics

Manual monitoring and reactive incident response are becoming unsustainable. AIOps platforms are getting smarter, correlating vast amounts of data to predict failures, automate remediation, and reduce 'noise'. Managers who can implement and fine-tune these systems will drastically improve operational efficiency and reduce downtime.

Anomaly Detection
Event Correlation
Intelligent Alerting
Automated Remediation

Advanced Cloud Cost Optimisation & Sustainability

Cloud spend is a huge line item for most businesses, and simply 'lifting and shifting' isn't enough anymore. Boards are increasingly asking about cloud sustainability (energy consumption). Managers need to go beyond basic FinOps to truly optimise and report on environmental impact.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be honest, managing IT infrastructure can feel like a never-ending game of whack-a-mole. But what if you could offload some of the repetitive, time-consuming tasks to AI? We're not talking about replacing your team, but giving them (and you) superpowers. Our AI Productivity Hub is here to help you do just that.

For an IT Infrastructure Manager, AI isn't just a buzzword; it's a practical tool that can free up significant time. Imagine automating root cause analysis, predicting system failures before they happen, or drafting incident reports in minutes. This isn't science fiction; it's what our best managers are already doing to focus on strategy and team development.

Automated Root Cause Analysis

Use AIOps platforms (like Datadog Watchdog or Splunk ITSI) to automatically analyse thousands of logs and metrics during an incident. This correlates events to pinpoint the likely root cause in minutes, not hours, helping your team fix things faster and preventing recurrence.

Predictive Capacity Planning

Stop guessing. Use AI models to analyse historical utilisation trends and business forecasts to predict future resource needs. Get alerts like 'Based on current growth, you will exhaust SAN capacity in 90 days,' giving you ample time to plan and procure.

Vulnerability & Patch Intelligence

Let an AI assistant read and summarise new CVE (Common Vulnerabilities and Exposures) reports. It'll cross-reference them with your asset inventory (CMDB) to instantly identify and prioritise at-risk systems, drastically cutting down on manual security research time.

Incident & Change Comms Generation

After an incident, feed key technical details into an AI model to generate a clear, non-technical summary for executive stakeholders or a detailed draft for the blameless post-mortem (RCA) document. This saves precious time when everyone is tired and stressed.

Common questions

How do you become an IT Infrastructure Manager?

Common routes in include Senior Infrastructure Engineer or Lead Engineer (3-5 years in a senior/lead role), Technical Architect (Infrastructure Focus) (4-6 years as an architect) and IT Project Manager (Infrastructure Projects) (5-7 years managing infrastructure projects). Times vary with prior experience.

Where can an IT Infrastructure Manager progress to?

This role can lead on to Director of Infrastructure & Operations (3-5 years in this role), depending on the skills you build.
