Job Description

Infrastructure Test Analyst

+ Hybrid / London

+ 40,000 to 45,000 per annum + benefits

The Client:

UK-based consultancy that helps organisations deliver digital transformation - offering managed services, cloud infrastructure and professional services (often around Microsoft Cloud)

The Role:

We're looking for an Infrastructure Test Analyst who lives and breathes the foundations of modern platforms-networks, servers, cloud, deployments, the whole engine room. If you enjoy validating complex systems, spotting weaknesses before they become outages, and generally keeping chaos at bay, you'll fit right in.

  • Testing infrastructure across network layers, compute, storage, virtualisation, and cloud services.

  • Running performance, failover, resilience, capacity, and security tests that actually mean something.

  • Ensuring CI/CD pipelines, deployment automation, and environments are built, configured, and behaving correctly.

  • Using observability tools (Splunk, Prometheus, CloudWatch, etc.) to track down issues before they become incidents.

  • Producing concise technical documentation-test plans, validation reports, defect logs-nothing fluffy.

  • Driving infrastructure testing automation using scripting and pipeline integration.



What You'll Bring

  • Solid experience testing infrastructure across Windows/Linux, virtualised platforms, and cloud (Azure/AWS/GCP).

  • Strong understanding of networking fundamentals, load balancing, firewalls, DNS, certificates, and IAM.

  • Hands-on experience with CI/CD tooling such as Azure DevOps, GitLab, or Jenkins.

  • Comfort working with logs, metrics, traces, and diagnostic tooling.

  • Scripting skills in PowerShell, Bash, or Python.



Desirable:

  • Knowledge of Terraform, Bicep/ARM, Ansible, or container platforms (Docker/Kubernetes).

  • Experience with performance test tooling or chaos/failover frameworks.

  • Relevant certifications (cloud, networking, ISTQB).



Who You Are

You're analytical, unflappable, and a natural problem-solver. You communicate clearly, you push for good engineering practice, and you don't panic when the monitoring dashboard turns red-you get curious.

If you want to work in an environment where infrastructure actually gets the attention it deserves, we'd love to hear from you.
