3What this role really is

This role covers designing, building and optimising the infrastructure that keeps a business running. It involves solving complex technical problems, improving how systems work, and helping less experienced staff develop their skills. The role sits at the centre of technical operations, keeping systems running smoothly, securely and efficiently.

4What you'd actually use

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

AWS/Azure/GCP (Cloud/IaaS) Advanced

Designing and implementing VPCs, configuring load balancers, auto-scaling groups, and writing Infrastructure as Code (Terraform, CloudFormation) for repeatable deployments. You'll be building in the cloud.

Okta/Azure AD (Identity & Access Management) Advanced

Configuring complex SSO/SAML integrations for new applications, implementing MFA policies and Conditional Access rules, and auditing permissions and access logs. You're the gatekeeper.

Jira Service Management/ServiceNow (IT Service Management) Advanced

Terraform/CloudFormation (Infrastructure as Code) Expert

Writing, maintaining, and reviewing IaC definitions to provision and manage cloud resources consistently and securely. You'll be defining our infrastructure in code.

Excel (Project Tracking/Basic Budget) Intermediate

Tracking project spend against a budget, managing task lists, and performing basic data analysis for reporting. Yes, it's still around.

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
Technical Design & Implementation Follows established design patterns and implementation guides; seeks approval for any deviation. Chooses between established design patterns; proposes minor modifications; seeks approval for significant changes. Designs new solutions from scratch, selecting appropriate technologies and architectural patterns within strategic guidelines; consults on major deviations.
Incident Resolution Executes defined troubleshooting steps; escalates quickly if solution isn't immediately apparent. Independently troubleshoots routine incidents; escalates novel or complex issues after initial investigation. Leads resolution of complex, non-routine incidents; determines root cause and implements preventative actions; manages communication during incidents.
Budgetary Spend (Tools/Services) No authority; requests tools/services via manager. Recommends tools/services up to £1K; seeks approval for all spend. Recommends and justifies tools/services up to £10K; seeks approval for anything above this threshold; manages project spend within allocated budget.
Process Improvement Identifies minor inefficiencies; suggests improvements to supervisor. Proposes and implements improvements to existing processes within their domain; seeks manager approval for changes. Designs and implements new processes or significant overhauls to existing ones; champions automation initiatives; consults with manager on strategic process changes.

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.

System Uptime for Tier-1 Systems
Keeping our most critical systems, like our core applications and identity providers, online and available.
Target · 99.95% (meaning less than 4 hours of downtime per year)

If our main customer database has 2 hours of unplanned downtime in a quarter, that's 99.99% uptime, hitting the target. If it's 10 hours, we've got a problem.

Project Delivery Rate
Completing assigned infrastructure projects and workstreams (e.g., new system deployments, major upgrades) on time and within the agreed scope and budget.
Target · 90% of projects delivered on schedule and within ±5% of budget

You're leading a new SSO integration project. If it's live by the agreed date and costs £48K instead of the planned £50K, that's a win. If it's two weeks late and £60K, we'll need to understand why.

Automation Rate for Routine Tasks
Identifying manual, repetitive systems administration tasks and automating them using scripting or orchestration tools.
Target · Reduce manual effort by 20% year-over-year for identified tasks

If a user onboarding process currently takes 30 minutes of manual effort per new hire, automating parts of it to bring that down to 15 minutes for 100 new hires saves 25 hours. We'll track these savings.

Incident Resolution Efficiency (MTTR)
The average time it takes to restore service after a critical incident, focusing on the systems you own or lead on.
Target · Average Mean Time To Resolution (MTTR) for P1/P2 incidents < 2 hours

You lead the resolution of a P1 database outage that takes 1 hour 45 minutes to fix. This contributes positively to the overall MTTR. We're looking for quick, effective fixes.

Solution Design Quality
How well your technical designs for new systems or major changes are structured, documented, and aligned with long-term strategy and security best practices.
  • Your designs are clear, well-reasoned, and reviewed positively by peers and the Head of Systems. Solutions are scalable and resilient, requiring minimal rework post-implementation. Documentation is thorough and easy for others to follow.
Mentorship Effectiveness
The impact you have on the growth and development of junior systems administrators or engineers, helping them improve their technical skills and problem-solving abilities.
  • Junior team members proactively seek your advice. They demonstrate improved autonomy and technical capability over time. Your code reviews are constructive and lead to better quality work from others. You're seen as a trusted technical guide.
Proactive Problem Management
Your ability to identify and address underlying issues (root causes) that lead to recurring incidents, rather than just fixing symptoms.
  • You lead thorough Root Cause Analyses (RCAs) for major incidents, identifying preventative actions. The number of recurring incidents related to systems you manage decreases over time. You propose and implement solutions that stop problems from happening again.
Stakeholder Trust & Collaboration
How effectively you work with other teams (e.g., Product, Security, Development) to understand their needs and integrate systems, building confidence in your technical leadership.
  • Other teams actively involve you in early planning stages for new initiatives. They trust your technical recommendations. You communicate complex technical concepts clearly to non-technical audiences, fostering good working relationships.

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 kick out of untangling a tricky network issue, optimising a database that's hitting performance limits, or designing a new system architecture that's both secure and scalable. The harder the problem, the more engaged you are.

Spending a day deep-diving into obscure log files and network traces to figure out why a specific application is intermittently losing connectivity, and then implementing a fix that prevents it from ever happening again.

Building Robust & Reliable Systems

There's a deep satisfaction for you in knowing that the infrastructure you've designed and implemented is solid, resilient, and just works. You're driven by the idea of creating something dependable that the entire business can rely on.

Successfully deploying a new identity management system that integrates seamlessly with 10 different applications, knowing it will drastically improve security and user experience for years to come.

Mentoring & Developing Others

You enjoy sharing your knowledge and experience, helping junior engineers understand complex concepts, debug their code, or approach a problem systematically. Seeing them 'get it' and grow is genuinely rewarding for you.

Spending an hour explaining the nuances of Infrastructure as Code to a junior team member, then reviewing their first Terraform module and offering constructive feedback.

What frustrates people
  • The 'Shadow IT' Cleanup: Spending a week untangling a critical business process from a SaaS tool someone bought on a credit card, which is now non-compliant and has no support.
  • Budgetary Whiplash: Being told to cut costs by 15% while simultaneously being asked to improve system uptime to 99.99% and support three new business-critical applications.
  • The Scapegoat Syndrome: When any application is slow or buggy, the default assumption from all sides is that it's an 'infrastructure problem' until proven otherwise.
  • Legacy System Babysitting: Being the only person who knows how to keep a 15-year-old, business-critical system running, which prevents you from working on strategic, modern initiatives.
  • The Security vs. Speed Battle: Constantly being perceived as the 'Department of No' because you have to enforce security policies that slow down developers or add friction for business users.
  • On-Call Fatigue: The relentless grind of the on-call rotation, knowing that a poorly-written line of code from another team can ruin your weekend.
  • Vendor Lock-in: Inheriting a critical system that is deeply integrated with a single, expensive vendor, leaving you with zero leverage for negotiation or innovation.
What this role does not give you
  • A purely greenfield environment: You'll be dealing with legacy systems and technical debt.
  • Complete autonomy on strategic direction: You'll design solutions, but the overall strategy comes from above.
  • A 9-to-5, no-stress routine: Incidents happen, and sometimes they happen at inconvenient times.

8Who you work with

Your work directly underpins the stability, security, and scalability of our entire technical estate. You'll be making decisions that affect system uptime, data integrity, and our ability to launch new products and services. Essentially, you're building the foundations that the rest of the business relies on, so your impact is felt across every department.

Inside the business
  • Head of Systems (your manager)
  • Project Managers (for new initiatives)
  • Product Development Teams (for system requirements)
  • Security & Compliance Teams (for audit and policy adherence)
  • Finance & Operations Teams (who rely on stable systems)
Outside the business
  • Key Technology Vendors (for platform support and roadmaps)
  • External Auditors (for compliance evidence)

9What you need before you start

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

  • At least 5 years of hands-on experience in a Systems Administrator or Systems Engineer role, with a proven track record of delivering projects.
  • Demonstrable experience in designing, implementing, and supporting complex infrastructure solutions in a production environment.
  • Solid understanding of cloud platforms (AWS, Azure, or GCP) with practical experience in their core services.
  • Strong scripting skills in Python or PowerShell for automation and system management.
  • A clear understanding of networking, security, and identity management principles.
  • Experience mentoring junior colleagues or leading technical workstreams.

10What to practise next

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

Cloud Native Security & Governance

As we move more workloads to the cloud and embrace containerisation and serverless, traditional perimeter security becomes less relevant. Security needs to be baked into every layer of the cloud-native stack, from code to infrastructure.

Container Security (e.g., Kubernetes) · Serverless Security · Cloud Security Posture Management (CSPM) · Identity-Based Segmentation

  • This week: Read up on the OWASP Top 10 for Kubernetes or Serverless.
  • This month: Take a specific certification in cloud security (e.g., AWS Certified Security - Specialty, Azure Security Engineer Associate).
  • Month 2: Lead a security review of one of our existing cloud-native applications, identifying potential vulnerabilities.
  • Month 3: Implement a new CSPM tool or integrate security scanning into our CI/CD pipelines for cloud deployments.

Quick win: Conduct a quick audit of our S3 bucket or Azure Blob storage permissions. Are they all locked down as they should be?

Advanced Infrastructure as Code (IaC) & GitOps

IaC is no longer just about provisioning; it's about managing the entire lifecycle of infrastructure, from deployment to configuration to policy enforcement, all through code. GitOps extends this by using Git as the single source of truth for declarative infrastructure.

Policy as Code (PaC) · State Management & Drift Detection · GitOps Workflows · Cross-Cloud IaC

  • This week: Review our existing IaC codebase. Identify areas where policy as code could be introduced.
  • This month: Experiment with a PaC tool like OPA or HashiCorp Sentinel in a sandbox environment.
  • Month 2: Design a GitOps workflow for deploying a non-critical application or infrastructure component.
  • Month 3: Contribute to a community project or open-source tool related to advanced IaC or GitOps.

Quick win: Automate the provisioning of a developer sandbox environment entirely through IaC, making it self-service.

11Staying current once you are in

What people here do to keep up
  • Actively participate in online technical communities (e.g., Stack Overflow, Reddit's r/sysadmin, GitHub projects).
  • Attend relevant industry webinars, conferences (virtual or in-person), and meetups to stay current with emerging technologies.
  • Contribute to open-source projects, especially those related to automation, cloud infrastructure, or security.
  • Dedicate time each week to 'tinkering' with new technologies in a sandbox environment, building proof-of-concepts.
  • Regularly engage in peer code reviews and technical discussions to share knowledge and learn from others.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, a lot of systems engineering involves sifting through logs, writing documentation, and repetitive tasks. What if you could offload some of that grunt work to AI? Imagine spending less time on the tedious bits and more on the really interesting, complex challenges.

We're not talking about replacing you; we're talking about giving you a seriously powerful co-pilot. AI tools are rapidly transforming how systems engineers work, helping you analyse vast amounts of data, automate routine processes, and even draft complex documentation much faster. Here's how you'll actually use AI to get more done and focus on what truly matters.

Predictive Outage Detection

Use AI-powered observability tools (think Dynatrace or Datadog) to analyse millions of logs and metrics in real-time. This helps you spot anomalies that predict potential system failures before they impact users. You'll be fixing problems before anyone even notices they're there.

Cloud Cost Optimisation Analysis

Leverage AI-driven FinOps platforms to make sense of complex AWS or Azure billing data. These tools automatically identify idle resources, recommend rightsizing opportunities, and forecast future spend with much greater accuracy than a human ever could. Saves you a headache during budget reviews.

Draft Policy & Documentation Generation

Feed your requirements into a secure LLM to generate a solid first draft of technical documentation or internal IT policies (like an Acceptable Use Policy or Data Retention Policy). The AI gives you a well-structured template that you can quickly refine, saving you hours of staring at a blank page.

Incident Report & Exec Summary Writing

After an incident, you can feed the technical timeline, logs, and resolution steps into an AI model. It'll then generate a clear, concise Root Cause Analysis (RCA) document and a separate, non-technical summary tailored for executive stakeholders. This means less time writing, more time preventing the next incident.
