Infrastructure Tester

Permanent opportunity

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

£42,000 - £45,000

Key Skills

• Infrastructure Testing experience
• AWS / Azure
• API
• Manual and automated testing experience

We're looking for a hands‑on Tester who is comfortable checking infrastructure deployments and systems performance as they validate user journeys in an app. You will work across 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 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 – 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.
