Payment terminals and secure hardware devices are at the core of today’s financial ecosystem. Ensuring they meet stringent global security requirements such as PCI PTS is essential. As a PCI PTS Security Evaluator, you will join a multidisciplinary team assessing the security of payment terminals and secure hardware modules with focus on hardware penetration testing, logical security testing, and tamper‑resistance evaluation.Key responsibilities include analysing architectures and embedded systems; performing side‑channel, invasive/semi‑invasive attacks, and probing; verifying secure boot, key management and firmware; firmware code reviews; using lab equipment (oscilloscopes, power analysis, drills/milling tools) for tamper testing; documenting attack paths and compliance; and contributing to internal R&D.Qualifications: Technical degree (BSc/MSc/PhD) in CS, EE, Embedded Systems, Physics, Mathematics or equivalent; interest/experience in board‑level probing/debugging (JTAG, SWD, UART); familiarity with logical security testing, secure firmware, crypto implementations and secure boot; strong learning mindset; teamwork; persistence and creativity; ability to write clear technical reports in English.
