You will work closely with engineers, and acquirers to deliver smooth and timely certifications. This is a critical position that combines technical depth, compliance expertise, learning abilities and strong cross-functional coordination.

• Manage and execute EMV Level 3 certification processes for all supported card schemes and regions

• Prepare, and execute structured test plans, using accredited tools (e.g., Fime/UL, ICCTmat, and similar)

• Collaborate with engineering teams to diagnose, reproduce, and resolve issues found during certification testing

• Maintain a deep and up-to-date understanding of EMVCo, scheme-specific and acquirer specific requirements, test cases

• Validate payment transaction flows and host responses, leveraging analytical skills to identify anomalies and ensure end-to-end correctness

• Document test evidence, defect logs, and status reports for internal and external stakeholders

• Support ongoing compliance by actively monitoring changes in EMV specifications, scheme mandates, and regional regulations, and proactively assessing their impact on existing products

Qualifications

• 3+ years of experience in quality engineering, test engineering, or a closely related technical discipline — with a track record of owning structured test execution within a product domain

• Strong analytical skills: ability to work through complex technical specifications, interpret test data, and translate requirements into well-structured test cases

• Genuine motivation to develop certification expertise and demonstrable willingness to build this knowledge rapidly are strongly encouraged

• Experience with test tooling and automation frameworks

• Ability to read and analyze logs, TLVs, APDUs, and transaction traces or equivalent experience interpreting structured technical data and debugging complex system behavior
