About the role

Key responsibilities & impact

Own quality strategy for checkout services: define and maintain the test strategy, risk-based testing plans, and acceptance criteria that align with product goals and regulatory requirements.
Design and implement scalable test automation: lead the creation of robust test frameworks (API, UI, integration, performance) and ensure maintainability, reusability, and fast feedback.
Champion security and compliance testing: collaborate with security, privacy, and compliance teams to validate controls (PCI-DSS considerations, data handling, encryption, access controls) and carry out threat modeling where appropriate.
Ensure reliability and performance at scale: plan and execute performance, soak, resiliency, and chaos testing; define SLOs/SLA-driven test coverage and reporting.
Validate payments workflows end-to-end: verify success flows, retries, refunds, cancellations, failed payments, fraud detection signals, and rollback scenarios across gateways, banks, and PSPs.
Improve quality metrics and visibility: establish meaningful metrics (defect escape rate, test coverage, automation ROI, MTTR) and provide actionable dashboards to stakeholders.
Collaborate across the lifecycle: work closely with product, platform, development, security, and SRE to embed quality into design, code, and release processes; participate in design reviews and incident post-mortems.
Drive risk-based release planning: assess release risks, define test windows, and ensure adequate coverage for changes in payments, risk rules, and integration points before production.
Mentor and elevate the team: coach software engineers, share best practices, review test plans and code, and help raise the overall quality culture.
Continuous improvement: lead initiatives for test automation, tooling, and process improvements; advocate for quality-focused culture and proactive defect prevention.
