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, Back End 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 life cycle.
Contribute to continuous improvement of QA practices, tools, and processes.
Skills & Experience
Proven experience in Infrastructuretesting (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.
If you'd like to discuss this role in more detail, please send your updated CV to (see below) and I will get in touch.
