+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
    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.

If you'd like to discuss this role in more detail, please send your updated CV to and I will get in touch.
