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, Cloud Watch, 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 Dev Ops, Git Lab, or Jenkins.

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

Scripting skills in Power Shell, 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
