    • Job Zusammenfassung

    In dieser Rolle entwickelst du Firmware in C++ für ARM Cortex-M Mikrocontroller, integrierst Smartphone-basierte Credentials und implementierst Sicherheitsprotokolle für mobile Anwendungen und Embedded Systeme.

    Job Technologien

    Deine Rolle im Team

    • As a Senior Firmware Developer, you will design and implement C++ application firmware on microcontrollers (ARM Cortex-M) running an RTOS. Your focus will be on application-level features and the integration of physical and smartphone-based credential processing flows (Mifare DESFire, HCE, mobile wallets).
    • Firmware Development: Implement C++ application-layer firmware on an RTOS (tasking, IPC, power-aware scheduling).
    • Credential Logic: Develop application logic for existing (Mifare DESFire) and future standards: app/file model, access conditions, personalization, and lifecycle management.
    • Connectivity & Workflows: Integrate NFC/BLE/WLAN stacks and mobile credential workflows (provisioning, HCE, revocation).
    • Security Implementation: Interface with secure elements / SAMs for key storage and transaction offload. Implement secure boot, signed/encrypted OTA, and application-level runtime protections.
    • Software Maintenance: Enhance and maintain internal software suites (C++, C#).
    • Testing & CI/CD: Build tests and CI/CD artifacts; use protocol sniffers and hardware debuggers for validation.
    • Collaboration: Work closely with mobile, backend, hardware, and QA teams; produce technical and security documentation.

    Unsere Erwartungen an dich

    Qualifikationen

    • Security: Familiarity with applied cryptography in embedded systems (secure messaging, AES/HMAC, key usage), secure elements / SAM integration, secure boot, and OTA.
    • Languages: Good German and strong English skills.

    Erfahrung

    • Experience: + 5 years of embedded firmware experience.
    • Core Skills: Strong C++ experience for microcontrollers in resource-constrained environments and practical RTOS experience (Zephyr is an advantage).
    • RFID/NFC: Hands-on RFID / NFC experience (ISO 14443, Mifare DESFire EVx preferred).
    • Mobile Credentials: Experience with smartphone credential flows (mobile wallets, HCE, provisioning).
    • Tools: Debugging skills (JTAG/SWD, logic analyser) and embedded CI/CD experience.
    • Nice to have: Deep Mifare DESFire EVx personalization experience, low-power design, mobile platform SDKs/APIs, knowledge of access control standards, security compliance (CRA, NIST, ETSI), and familiarity with Git, Jira, and embedded test frameworks.
