3What this role really is

A systems engineer keeps servers, networks and cloud platforms running and secure. The work involves building, maintaining and troubleshooting the systems a business depends on.

4What you'd actually use

The tools this job runs on, and how well you'd need to know each one.

Cloud Platforms (AWS, Azure, or GCP) Intermediate

You'll independently deploy, manage, and troubleshoot virtual machines, storage, and networking components within at least one major cloud provider. You'll use the console and CLI regularly.

Terraform & Ansible Intermediate

You'll apply existing Terraform plans to provision resources and execute Ansible playbooks for configuration management. You can read the code, understand its intent, and make minor, approved modifications.

Docker & Kubernetes (kubectl) Basic

You'll deploy pre-built Docker images to a Kubernetes cluster and use `kubectl` to inspect pods, services, and logs for basic troubleshooting and health checks.

Datadog, Grafana, or New Relic Intermediate

You'll use these dashboards to monitor system health, respond to pre-configured alerts, and create simple custom dashboards for specific services you manage.

ServiceNow or Jira Service Management Intermediate

You'll manage incidents, changes, and service requests strictly within our ITSM platform, making sure all your work is logged and tracked according to ITIL processes.

Linux/Windows Server Administration Intermediate

You'll be comfortable with command-line administration, scripting (Bash/PowerShell), user management, and basic troubleshooting on both Linux and Windows server environments.

5What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing in Where you are nowThe step above
Incident Resolution Follow runbook, escalate to senior engineer if outside defined steps. Independently diagnose and resolve P2/P3 incidents using runbooks and your own troubleshooting skills. Escalate P1s immediately and novel issues to a senior engineer. Lead P1 incident response, define new runbooks, make critical real-time decisions during outages, and decide on rollback strategies.
Infrastructure Changes Execute pre-approved changes under direct supervision, following detailed instructions. Implement standard changes (e.g., patching, resource scaling) after manager/lead approval. Propose minor changes to existing IaC, but require review before deployment. Approve minor changes. Design and implement significant infrastructure changes. Present proposed changes to the Change Advisory Board (CAB).
Tool Selection & Methodology Use tools and methodologies as directed by senior team members. Choose the best approach for routine technical problems within established toolsets. Propose new tools or methodologies for specific problems, but don't expect to make the final call. Select and recommend new technical tools and methodologies for workstreams. Influence team-wide adoption and best practices.
Budget Allocation No budget authority. Awareness of cloud costs for resources you manage. Inform manager of potential cost-saving opportunities or unexpected spend. No direct spending authority. Manage small project budgets (up to £5K). Influence larger budget decisions by providing data and recommendations.

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.

Incident Resolution Time (MTTR)
How quickly you get services back up and running after an incident.
Target · < 2 hours for P2 incidents, < 4 hours for P3 incidents

A database server goes offline. You're expected to diagnose and restore it within 2 hours, not 4.

Change Success Rate
The percentage of changes you implement that go smoothly without causing new issues.
Target · > 98%

You deploy a new firewall rule; it works as expected and doesn't break existing applications.

System Uptime for Managed Services
The availability of the specific systems or services you're responsible for.
Target · 99.9% (the 'three nines')

The web servers you manage are available for 99.9% of the month, meaning less than 43 minutes of unplanned downtime.

Automation Script Contributions
The number of new scripts or improvements to existing automation you contribute.
Target · Roughly 1-2 impactful scripts or improvements per quarter

You write a Python script to automate a repetitive daily health check that used to take 15 minutes manually.

Problem-Solving Effectiveness
Your ability to logically diagnose and fix issues, not just treat symptoms.
  • You'll be able to clearly explain your troubleshooting steps in post-mortems. You'll identify root causes, not just quick fixes. You'll get fewer repeat incidents for issues you've 'fixed' before.
Adherence to Operational Processes
How well you follow our established ITIL processes for incident, problem, and change management.
  • All your changes will have approved change requests. Incidents will be thoroughly documented in ServiceNow. You'll close tickets with clear resolution notes. You won't be taking shortcuts that could cause bigger problems later.
Collaboration with Development Teams
Your ability to work effectively with our software development teams when their applications need infrastructure support or changes.
  • Dev teams will tell us you're easy to work with. You'll proactively communicate infrastructure changes that might affect them. You'll help them troubleshoot application issues from an infrastructure perspective without just saying 'it's your code'.
Documentation Quality
How well you maintain and update our runbooks, system diagrams, and knowledge base articles.
  • Other engineers can follow your documentation to perform tasks or troubleshoot issues. Your diagrams are up-to-date. New joiners find your contributions helpful for learning the ropes.

7Would you like it

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

What people enjoy
Solving Tricky Technical Problems

You'll get a real kick out of diagnosing a complex network issue or figuring out why a cloud resource isn't behaving as expected. It's the puzzle-solving aspect that keeps you engaged.

Spending an afternoon digging through logs and network traces to pinpoint a subtle routing issue that was causing intermittent application errors.

Learning New Technologies

You're always keen to get your hands on new tools, whether it's a different cloud service, a new IaC framework, or a monitoring platform. You enjoy the process of mastering new tech.

Volunteering to be the first to experiment with a new serverless offering from AWS, even if it's just for a proof-of-concept.

Direct Impact on System Stability

There's a genuine satisfaction in knowing that the work you do directly contributes to keeping our services online and reliable. You see the immediate benefit of your efforts.

Successfully implementing a monitoring alert that catches a disk space issue before it causes an outage, preventing a potential P1.

What frustrates people
  • The 3 AM Page: Being woken up for an alert that turns out to be a false positive or a non-critical issue that could have waited until morning. It happens, more often than you'd like.
  • "It's a Network Problem": The default assumption from application teams when their code fails, leading to hours spent proving the network is actually fine. You'll get used to it.
  • Legacy Tech Debt: Being responsible for a critical, 20-year-old system that no one understands, has no documentation, and which you're not given the budget to replace. Yes, it's boring. Yes, you have to do it.
  • The Bureaucratic CAB: Sitting through a 2-hour Change Advisory Board meeting to get approval for a 5-minute, low-risk change. It's part of the game.
  • The Cost Centre Stigma: Your department's successes (i.e., nothing breaks) are invisible, but your failures are immediately visible to the entire company. You're often seen as a cost to be minimised, not a value driver. It's a reality we deal with.
What this role does not give you
  • Constant greenfield projects: While you'll get to build new things, a good chunk of your time will be maintaining existing systems.
  • Complete autonomy over strategic direction: You'll have autonomy on how you do your work, but the 'what' is usually defined by senior engineers or leads.
  • A quiet, predictable 9-to-5: Incidents don't care about your schedule, and sometimes you'll need to be flexible.

8Who you work with

You're directly responsible for the operational health of our IT systems. If you're doing well, our applications stay online, our data is safe, and our colleagues can get their work done without technical hiccups. If things go south, it can mean anything from a few frustrated users to a major business outage, which, frankly, costs us money and reputation.

Inside the business
  • Your Manager (for guidance and priorities)
  • Other Infrastructure Engineers (for collaboration and knowledge sharing)
  • Development Teams (when their applications need infrastructure support)
  • Security Operations (for making sure we're compliant and safe)
  • Service Desk (for escalating and resolving user-reported issues)
Outside the business
  • Cloud Providers (AWS, Azure, GCP support teams)
  • Hardware/Software Vendors (when you need technical assistance)

9What you need before you start

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

  • At least 2-3 years of hands-on experience in an IT operations, systems administration, or cloud support role.
  • Solid understanding of networking concepts (TCP/IP, DNS, firewalls, VPNs).
  • Proficiency in at least one scripting language (Bash, PowerShell, Python) for automation.
  • Experience with incident management and change management processes, ideally within an ITIL framework.
  • A genuine desire to learn and adapt to new technologies—the infrastructure world changes fast, you know.

10What to practise next

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

Advanced Container Orchestration (Kubernetes)

While you're currently deploying images, the future means understanding how Kubernetes actually works under the hood. We'll be doing more complex deployments, managing networking, storage, and security within clusters.

Kubernetes networking (CNI, Services, Ingress) · Persistent storage (CSI, StorageClasses) · Security contexts and network policies · Helm charts for application packaging · Troubleshooting complex pod failures and cluster i

  • This month: Take an online course on Kubernetes fundamentals beyond basic `kubectl` commands.
  • Next quarter: Set up a small local Kubernetes cluster (e.g., Minikube, Kind) and deploy a multi-service application.
  • Within 6 months: Get comfortable writing and deploying Helm charts for simple applications.
  • Within 12 months: Understand how to diagnose and fix common networking or storage issues within a K8s cluster.

Quick win: Spend time exploring the Kubernetes documentation. Understand the difference between a Deployment, a Service, and an Ingress. It's a steep learning curve, but totally worth it.

Security Automation (DevSecOps Principles)

Security can't be an afterthought; it needs to be built into our infrastructure from the start. This means automating security checks, policy enforcement, and vulnerability scanning as part of our CI/CD pipelines.

Static Application Security Testing (SAST) and Dyn · Infrastructure vulnerability scanning (e.g., Trivy · Secrets management (e.g., HashiCorp Vault, AWS Sec · Automated policy enforcement in IaC · Integrating security tools into CI/CD pipelines

  • This month: Research common DevSecOps tools and principles.
  • Next quarter: Experiment with a vulnerability scanner for Docker images or IaC templates.
  • Within 6 months: Propose an automated security check to be added to one of our existing CI/CD pipelines.
  • Within 12 months: Understand how to manage secrets securely across our infrastructure.

Quick win: Read up on the OWASP Top 10. Understand basic security risks and how they apply to infrastructure. Start thinking about 'shift left' security.

11Staying current once you are in

What people here do to keep up
  • Regularly participate in industry webinars and online forums (e.g., Reddit's r/sysadmin, r/devops) to stay current with trends.
  • Contribute to open-source projects, especially those related to IaC, automation, or monitoring—it's a great way to learn and build a public portfolio.
  • Attend local tech meetups or conferences (when possible) to network and learn from peers.
  • Dedicate a few hours each week to personal learning projects, experimenting with new tools or cloud services in your own sandbox environment.

12The rising capability

The rising capability

Zavmo analysis

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.

Advanced Infrastructure as Code (IaC) Patterns

As our infrastructure grows, manual changes become impossible and even basic IaC can get messy. We'll need to move towards more modular, reusable, and self-service IaC to keep things scalable and manageable.

  • Terraform modules and workspaces for environment i
  • Policy as Code (e.g., OPA, Sentinel) for governanc
  • GitOps principles for continuous deployment of inf
  • Managing IaC state securely and at scale

Serverless Architecture & Operations

Serverless computing (like AWS Lambda, Azure Functions) is becoming more prevalent for specific workloads. It means less server management for us, but a different set of operational challenges around monitoring, cost, and deployment.

  • Event-driven architectures and triggers
  • Cold starts and performance optimisation
  • Cost management for serverless functions
  • Monitoring and logging serverless applications
  • Security considerations for function permissions

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, a lot of infrastructure work can feel repetitive, or you're just sifting through mountains of data. We're not about replacing you with AI; we're about giving you superpowers. Imagine getting back hours every week to focus on the truly interesting, complex problems.

In IT Infrastructure & Operations, AI isn't just a buzzword; it's a practical tool that can seriously speed up your day. From automatically sifting through alerts to drafting your post-mortems, we're building an 'AI Hub' to help you work smarter, not harder. Here’s how you’ll actually use it:

Automated Incident Triage & Correlation

Forget sifting through hundreds of alerts. Our AI analyses incoming alerts from Datadog, Splunk, and other systems, suppresses the noise, and correlates related events into one actionable incident. It even tries to guess the impacted service, giving you a massive head start.

Predictive Failure Analysis

Imagine knowing a server is about to fail before it actually crashes. Our AI models look at CPU, memory, and disk latency data, spotting subtle anomalies that humans miss. It'll create a predictive ticket for you to investigate, turning reactive fire-fighting into proactive problem-solving.

Intelligent IaC & Script Generation

Stuck writing boilerplate Terraform or a repetitive Python script? Tools like GitHub Copilot are integrated into our workflow. They'll give you context-aware suggestions and even draft entire code blocks, drastically speeding up how you create automation and infrastructure definitions. It's like having a coding assistant always by your side.

Automated RCA & Post-mortem Drafts

After a major incident, the last thing you want to do is spend hours writing up the Root Cause Analysis (RCA). Our AI can ingest the incident timeline, alert data, and even the 'war room' chat logs to generate a structured first draft of the RCA document. You just need to review, refine, and add the human insights.
