## Description

The Senior Principal Platform Engineer – QA will help shape and evolve the organisation's quality engineering platform, enabling teams to build, test, deploy and operate software faster, more securely, and more reliably.

**Quality strategy and architecture**

- Define the platform quality engineering strategy, test pyramid and quality gates for all cloud platform products.

- Set standards for testing infrastructure-as-code: static analysis, policy-as-code, unit, integration and end-to-end tests for Terraform modules.

- Design ephemeral test environments that provision, validate and tear down platform stacks on every change.

**Continuous verification and automation**

- Build shift-left quality into CI/CD: automated gates for security, compliance, cost and drift before merge and release.

- Establish contract and compatibility testing so module and API changes never break consuming business teams.

- Lead resilience and chaos testing for platforms.

- Drive performance and scale testing for self-service provisioning paths.

**GxP and computerised system assurance**

- Modernise qualification from document-heavy validation to risk-based, automated Assurance.

- Generate qualification evidence (IQ/OQ traceability, test results, approvals) directly from pipelines.

- Partner with Quality, GRC and the CISO office to keep evidence audit-ready for GxP, SOX and data integrity requirements.

**Images, supply chain and security quality**

- Own test frameworks for VM, OS, database and container image bakeries: CIS benchmarks, vulnerability thresholds, SBOM and signing checks.

- Integrate CNAPP and code scanning findings (e.g. Wiz, GitHub Advanced Security) into release gates with clear SLAs.

**AI and agentic platform quality**

- Define evaluation frameworks for platform AI agents: accuracy, safety & guardrail

- Test agent-generated artifacts for correctness, policy compliance and blast radius before execution.

**Engineering leadership**

- Set quality metrics and SLOs, report them to platform and security leadership, and drive corrective actions.

- Mentor engineers across platform teams; grow a quality-engineering community of practice.

- Evaluate and select tooling; make build-vs-buy recommendations.
