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 software 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.
