Junior Embedded Software Engineer - Secure IoT Firmware (m/f/d)
NXP Semiconductors · Gratkorn
Join our team working at the intersection of embedded security and connected IoT devices. As a Junior Embedded Software Engineer, you will contribute to firmware powering secure device provisioning, over-the-air updates, and trusted execution environments on Arm Cortex-M MCUs. This is an excellent opportunity for candidates early in their career who are eager to build expertise in embedded security and connected device lifecycle management.
Your Responsibilities
- Develop and test Provisioning Firmware that securely binds devices to specific OEMs at manufacturing sites (RTP provisioning).
- Implement and validate a security framework for trusted execution on Arm Cortex-M MCUs, including core components and example applications.
- Build and test secure key provisioning applications running on FreeRTOS and Zephyr RTOS.
- Develop and maintain OTA Firmware Update flows for connected devices.
- Manage distribution and release of embedded SW through multiple distribution portals.
- Contribute to the architecture and design of secure device management solutions.
- Collaborate with the backend team on microservices responsible for device abstraction.
Your Profile
- University degree in Software Engineering, Computer Science, Electrical Engineering, or a related field.
- Strong C programming skills; experience with Assembler is a plus.
- Solid understanding of 32-bit microcontroller architectures and embedded software design.
- Exposure to embedded software verification methodologies (unit testing, integration testing).
- Curious, fast learner — comfortable picking up new tools, standards, and protocols quickly.
Nice to Have:
- Knowledge of embedded security concepts: cryptographic algorithms, Arm TrustZone, secure boot.
- Scripting experience in Python or Groovy for build/test automation.
- Object-oriented programming background in Java (relevant for backend collaboration).
- Experience with RTOS environments (FreeRTOS, Zephyr).
What Makes This Role Unique
- Work on security-critical firmware that ships in millions of IoT devices worldwide.
- Gain hands-on experience with security frameworks, TrustZone, and NXP's embedded security ecosystem.
- Bridge embedded firmware and backend services — a rare full-stack IoT security perspective.
Please note: The successful candidate may/will be responsible for security related tasks. The assignment may/will be in scope of security certifications, therefore a conscious and reliable way of working is necessary.
