Senior QC Engineer (QA QC, AI)

Own the quality assurance function end-to-end for a high-growth enterprise engineering organisation on a 500M€ growth mandate. You are not a gatekeeper at the end of a pipeline, you are embedded from requirements to release, shifting quality left and automating everything that can be automated.You write code. You build frameworks. Manual testing is your documented exception, not your default.We are building AI-native. You will validate traditional software behaviour and AI outputs: LLM responses, agent workflows, inference accuracy, and failure modes unique to non-deterministic systems. Nothing ships without your sign-off. You report directly to the Tech Lead and CEO.SCOPE & IMPACTQA StrategyOwn org-wide QA strategy: coverage targets, risk frameworks, release gates, and escalationsDefine and enforce a Definition of Done - no sprint closes without quality criteria metOwn bug triage: severity SLAs, P0/P1 post-mortems, defect escape tracking, metrics published continuouslyBuild and own end-to-end test automation: E2E (Playwright/Cypress), API (Pact/Newman), Performance (k6/Gatling), Security (OWASP ZAP)All automation integrated into CI/CD, no merge to main without gate passing; 80% automation ratio within 6 monthsDesign test strategies for non-deterministic AI systems: accuracy thresholds, hallucination detection, failure taxonomiesBuild evaluation harnesses for LLM responses and agent workflows end-to-endCreate regression suites that detect silent model degradation on updateCollaborate with AI engineering on production observability hooks for quality signalsRelease Governance & SecurityOwn the release sign-off process, no feature goes to production without documented QA approvalDefine environment promotion criteria (dev → staging → production) with automated quality gates at each transitionOWASP Top 10 coverage; SAST on every PR; DAST on every release candidate; GDPR/PII flow validationFull test traceability and documented sign-off for the clinical verification application (regulated domain)Shift-Left & Developer EnablementEmbed QA from requirements stage: review specs, challenge acceptance criteria, flag testability gaps before code is writtenPair with developers on test-driven approaches; run QA onboarding for every new engineerThe Quality Bar You Will Set & HoldZero critical or high defects to production - every escape triggers a post-mortem≥80% automation ratio within 6 months - manual testing requires documented justification100% critical path API contract coverage - breaks caught in CI, not stagingSLOs defined and enforced per product track - regressions detected before users feel themAI output accuracy thresholds defined per use case - every AI feature has a test harnessEvery release signed off, documented, and traceable.
