This role sits at the center of our Level 2 certification work. Adyen develops its own L2 kernels (contact & contactless), and you will own their certification end to end: coordinating type approval testing with our external certification lab, analyzing test results, and translating findings into clear, actionable reports for our kernel developers to work from. We are motivated individuals who tackle unique technical challenges at scale and solve them as a team. Together, we deliver innovative and ethical solutions that help businesses achieve their ambitions faster. What you will do Adyen develops its own L2 payment kernels, which sit at the core of every in-person transaction we process. • You will own the technical preparation and execution of Level 2 kernel certification , ensuring our kernels meet EMVCo type approval requirements as well as the contact and contactless specifications of Visa, Mastercard, Amex, Discover, JCB, UnionPay, existing local payment method & planned future payment method expansions as Adyen's In-Person Payment business expands. • You will sit directly between our external certification lab and our engineering teams. That means owning the lab relationship end to end , and translating what comes back from testing into something engineers can act on. • When a test fails, you investigate at the APDU and transaction-flow level , identify the root cause, and guide the kernel developers toward the fix rather than simply handing over a failure report. • You will own the certification calendar : managing your own time and the wider timeline so submissions land when they need to, and so delta certifications triggered by kernel changes or expiring approvals never become a surprise. Who you are • You have at least 2 years of hands-on experience performing Level 2 certifications for contact and contactless kernels. • Experience with EMV Level 3 brand certification is a significant plus, as it gives you visibility into how kernel behavior surfaces in end-to-end scheme testing. • You have strong EMV knowledge at the kernel level : EMVCo contact and contactless specifications, terminal application flow, CVM processing, and cryptogram generation. • You are comfortable working with EMV test tooling and card simulators , and reading APDU traces to diagnose exactly where a transaction went wrong. • You are an excellent communicator . You can explain a certification failure to an engineer in terms they can act
