QA Test Infrastructure Engineer

Summary: The QA Test Infrastructure Engineer role involves designing, building, and delivering secure digital solutions within highly secure environments. The engineer will collaborate with various specialists to enhance technology that supports critical operations. Key responsibilities include ensuring product quality, analyzing infrastructure requirements, and applying secure design principles. The position requires the highest level of security clearance due to the sensitive nature of the work.

Key Responsibilities:

• Ensuring quality of products as they move from prototype/proof of concept into Production.
• Analyse infrastructure requirements and architectures; identify test conditions; maintain traceability; log risks.
• Create infrastructure-focused test strategies and plans defining scope, environments, tooling, automation, and governance entry/exit criteria.
• Provision and validate test environments in collaboration with DevSecOps, ensuring OS, network, platform services, monitoring, and pipelines align to readiness standards.
• Design and execute tests across physical infrastructure and IaC, including functional, integration, regression, resilience, non-functional, and security-related scenarios.
• Apply Secure-by-Design principles; support security testing; contribute to accreditation, assurance, and compliance documentation.
• Strong understanding of TCP/IP, DNS, DHCP, routing, switching, firewalls, VLANs, and related network behaviours.
• Experience with physical infrastructure setup and troubleshooting (routers, switches, cabling).
• Proficiency with Linux/Unix command line for diagnostics, configuration, and validation.
• Experience working across virtualisation platforms (VMware, VirtualBox) and cloud environments (AWS, Azure, GCP).
• Terraform: writing/validating HCL, managing state, using modules.
• Ansible: building playbooks/roles, inventories, and validating idempotency.
• Kubernetes: deploying workloads, validating manifests, managing clusters, and testing containerised applications.
• Familiarity with CI/CD tooling (Jenkins, GitLab CI, GitHub Actions).
• Experience integrating IaC validation and environment checks into automated pipelines.
• Understanding of pipeline gating, automated readiness checks, and environment orchestration.
• Strong grounding in Secure-by-Design principles, IAM, least privilege, OS hardening, network segmentation, and observability.
• Experience within regulated or highly governed environments (eg, MOD or similar).
• Ability to support compliance, assurance, and accreditation activity.
