Quality Assurance Tester

Quality Assurance Tester (Outside IR35) Hybrid (Holborn/London) Every client integration today runs its own ad-hoc QA loop, with escalations and finger-pointing when something behaves unexpectedly. This role owns end-to-end QA for each client account: from pre-prod TestFlight access through production rollout, campaign setup, validation of all use-cases (e.g. Best Moment), and ongoing data quality. It sits inside CDA and is the trusted QA partner for each client pod. Core responsibilities

• Lead UAT and release readiness for each client integration — go/no-go gates, TestFlight and test-build coverage, production credential checks, gradual rollout management (% enabled, PNS), debug-screen removal sign-off.
• Validate campaign setup and execution via the Console: deep links, PNS firing, Best Moment behaviour across scenarios, audience targeting; ensure outputs match expectations as we scale audiences.
• Confirm each client's microsegment & custom microsegment configuration (e.g. installed apps!) is correct for their SDK version, app structure and use case — flag mismatches before the client does.
• Verify SDK signals on the real client app: report flow into JemaAPI, Bugsnag crash logs, microsegment reports per device; cross-check internal tools for active users and SDK health.
• Triage and route client-side defects: cleanly separate SDK-platform issues from client-app issues, and stop escalations from turning into fire drills.
• Apply fixes systematically across other clients that would benefit from the same fix — no client silently behind.
• Maintain auditable per-client QA documentation: what was tested, what was promised, what is bridged offline, what is blocked, what changed between versions. What success looks like
• Every client deploy has a known QA state, a clear go/no-go, and a closed loop on every issue found.
• Client-side regressions are caught before the client notices them.
• Cross-client fixes are propagated proactively; no client is silently behind on a known fix.
• CDA pods have a trusted QA partner who reduces escalation noise to Engineering and Product. Essential experience
• Owned UAT and release quality for enterprise B2B deployments, ideally involving a mobile SDK and a console/campaign-management surface.
• Strong on data validation (SQL, monitoring tools) and on reasoning across pipelines, APIs and customer-facing outputs.
• Excellent stakeholder communicator — calm under client pressure, clear with engineering, credible with delivery leadership.
• Pattern-matcher: spots the same defect class repeating across accounts and works upstream to fix the source.
