## About the Role

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.

## Description

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.
