Mobile Acceptance Architect (SoftPOS, NFC & CPACE)

O projekcie We are building a next-generation Digital Currency payment ecosystem that transforms standard commercial off-the-shelf (COTS) smartphones into secure, certified payment terminals using CPACE-based SoftPOS and NFC technology-completely removing the need for external peripheral hardware.

As the Mobile Acceptance Architect, you will own the edge acceptance layer and low-level mobile architecture driving Europe’s future sovereign contactless payments.

What we offer

• Unique greenfield R&D challenge at the intersection of low-level mobile engineering, NFC kernels, and next-gen Digital Currency.
• High autonomy and technical leadership over the entire mobile acceptance SDK and kernel architecture.
• Long-term B2B contract, 100% remote work, and competitive remuneration.

Zakres obowiązków

• Architect the SoftPOS strategy, designing native mobile frameworks, SDK architectures, and security wrappers for CPACE contactless acceptance, web checkouts, and app-to-app payment flows.
• Lead low-level hardware and OS adaptation to securely interface with native Android and iOS NFC controllers, Secure Elements (SE), and Hardware Abstraction Layers (HAL).
• Translate complex European contactless payment specifications (CPACE and EMVCo) into executable mobile software blueprints and optimized device kernels.
• Partner closely with cryptography teams to implement White-box Cryptography, RASP, and secure PIN entry mechanisms directly on standard commercial smartphones (COTS)

Wymagania

• 6+ years of architectural experience focused on Mobile Point-of-Sale (mPOS), SoftPOS, digital wallets (Apple Pay / Google Wallet architectures), or embedded payment terminal firmware.
• Architectural mastery of native mobile platforms (Android and iOS), low-level C/C++ implementations, and secure mobile memory management.
• Deep understanding of EMVCo Level 1 / Level 2 Contactless Kernels, NFC protocols (ISO/IEC 14443), and CPACE contactless payment extensions.
• Practical experience interfacing with native Android/iOS NFC controllers, Secure Elements (SE), and Hardware Abstraction Layers (HAL).
• Hands-on background in mobile edge security, including White-box Cryptography, Runtime Application Self-Protection (RASP), and secure PIN-on-glass mechanisms on COTS devices.
