Test Engineer (Infrastructure & Migration Validation) (RARR Job 5886)

Purpose of the role
Lead infrastructure and migration validation activities following cloud migrations, assuring platform functionality, connectivity, data integrity, resiliency, and observability for containerised workloads in a regulated clinical environment.

Key responsibilities

• Design, maintain, and execute infrastructure and migration test strategies covering networking, connectivity, security, compute, storage, identity, and data paths across Azure and hybrid environments
• Define and run smoke, functional, and non-functional tests to validate hub-and-spoke / Virtual WAN routing, private endpoints, firewall/NVA controls, WAF ingress, and application connectivity
• Validate containerised services deployed to App Service for Containers, Azure Container Apps, and AKS, including service health, scaling behaviour, logging, secrets management, backup, and recovery
• Verify data migration outcomes to Azure PostgreSQL Flexible Server, including schema validation, data integrity checks, performance validation, and rollback testing
• Collaborate with platform engineers, software engineers, and external vendor technical teams to define test scenarios, acceptance criteria, and cutover readiness
• Produce clear test evidence, defect reports, and assurance artefacts to support stage gates, clinical safety reviews, and formal go-live sign-off

Experience & skills

• Senior-level experience in test engineering or technical assurance roles supporting cloud or infrastructure migrations
• Proven experience designing and executing test strategies for complex systems, including network connectivity, identity, data platforms, and hybrid integrations
• Hands-on experience validating container-based and PaaS platforms (App Service for Containers, Azure Container Apps, or AKS)
• Strong understanding of non-functional testing concepts, including performance, resilience, failover, and rollback
• Comfortable working with technical teams and vendors to challenge assumptions, raise defects, and drive remediation in regulated environments

Technology & Tooling

• Azure platform areas under test: hub-and-spoke or Virtual WAN networking, private endpoints, firewall/NVA controls, DNS, identity, and security configuration
• Compute & runtime platforms: App Service for Containers, Azure Container Apps, and AKS (validation and testing perspective)
• Data & storage: Azure PostgreSQL Flexible Server, Azure Files and Blob Storage (performance, integrity, backup/restore validation)
• Observability: Azure Monitor and Log Analytics for validation of logs, metrics, alerts, and dashboards
• Integration testing: API connectivity via API Management and external vendor systems
• Test tooling: API and performance test tools (e.g., k6, JMeter, Postman), scripting for connectivity and validation, Azure diagnostics
• Infrastructure-as-code: ability to read and understand Terraform/Bicep outputs for test planning and validation (not authoring)

Preferred certifications
ISTQB, AZ‑104/AZ‑204 (or equivalent).
