What You’ll Do
As a QA Test Infrastructure Engineer , you’ll help design, build, and deliver secure digital solutions in highly secure environments. You’ll work alongside engineers, architects, and delivery specialists to develop technology that enables faster, safer decision-making for critical operations.
Your work may include:
- 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.
What We’re Looking For
We value people who take ownership, think critically, and enjoy working as part of a collaborative team tackling complex challenges. You don’t need to tick every box, but we’re particularly interested in people with skills/experience in:
Infrastructure, Networking & Operating Systems
- 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).
Infrastructure as Code (IaC)
- 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.
CI/CD & Automation
- 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.
Security & Compliance
- Strong grounding in Secure-by-Design principles, IAM, least privilege, OS hardening, network segmentation, and observability.
- Experience within regulated or highly governed environments (e.g., MOD or similar).
- Ability to support compliance, assurance, and accreditation activity.
