Job description

Infrastructure Tester

+Permanent opportunity

+Hybrid working on site in London 2/3 days a week

+£42,000 - £45,000

Skills:

+Infrastructure Testing experience

+AWS / Azure

+API

+Manual and automated testing experience

We're looking for a hands-on Tester who's as comfortable checking infrastructure deployments and systems performance as they are validating user journeys in an app. You'll work across a range of environments - from cloud setups and APIs to end-user interfaces - ensuring everything we ship is rock solid, performant, and secure.

This isn't a "click-around-and-tick-boxes" testing role. We need someone with strong technical grounding, curiosity, and the confidence to dive into environments beyond just the front end.

Key Responsibilities

• Execute and maintain test plans for infrastructure, backend services, and application layers.

• Validate deployments, configuration changes, and environment stability across cloud and on-prem environments (AWS, Azure, GCP, CI/CD).

• Perform integration, regression, and performance testing across multiple platforms.

• Collaborate with DevOps, Developers, and Product teams to identify and resolve issues early in the lifecycle.

• Contribute to continuous improvement of QA practices, tools, and processes.

Skills & Experience

• Proven experience in Infrastructure testing (manual and/or automated).

• Familiarity with infrastructure and deployment environments such as AWS, Azure, GCP, or on-premises.

• Experience testing APIs, services, and integration points, not just front-end UI.

• Strong analytical mindset and attention to detail - you spot issues others miss.

• Bonus: experience with scripting (Python, Bash, PowerShell) or IaC validation (Terraform, Ansible).

What We Offer

• Competitive salary of £45,000

• Hybrid working model - flexibility to split time between home and our London office

• Supportive, collaborative culture with a focus on continuous learning

• Opportunities to shape testing approaches and tools in a modern, cloud-focused environment

If you're an inquisitive, technically-minded tester who thrives in diverse environments and enjoys getting into the details that make systems stable and scalable - we'd love to hear from you.
