Job summary

Qualifications

• 5-10+ years' software quality engineering or development experience, including hands-on automation and cross-team technical leadership.
• Advanced programming skills in at least one modern language, building scalable automation frameworks rather than record-and-playback.
• Deep experience testing cloud-native SaaS at scale: distributed systems, APIs, asynchronous workflows and multi-tenancy.
• Proven expertise in performance, scalability and resilience testing, including workload design and reading production telemetry.
• Strong knowledge of CI/CD, containers, test-environment orchestration, test-data management and service virtualisation.
• The ability to lead ambiguous initiatives, communicate risk clearly and influence release decisions without positional authority.
• Degree in Computer Science, Engineering or a related field, or equivalent practical experience.

Responsibilities

• Own cross-team quality strategy, automation architecture and risk-based coverage for distributed SaaS services, APIs and SDKs.
• Design and build reusable automation frameworks, test libraries, service simulators and deterministic test data.
• Embed unit, integration, contract, API, end-to-end and regression testing into CI/CD with meaningful quality gates.
• Lead performance and scalability testing, including load, stress, spike, soak and capacity, against agreed service objectives.
• Define resilience testing for dependency failures, network disruption, timeouts, partial outages and graceful degradation.
• Partner with Security to validate identity, delegated authorisation, tenant isolation and evidence integrity, including negative and boundary cases.
• Establish production-representative test environments and validate upgrades, migrations, backward compatibility and rollback.
• Lead complex defect investigations using logs, traces and metrics, and drive cross-team root-cause analysis.
• Build quality reporting that makes coverage, escaped defects, performance risk and release readiness transparent.
• Mentor quality and software engineers and lead test-design reviews.
