Responsibilities

• Technical Leadership within the MCU Software team. Lead the technical planning, work assignments, and implementation for the new products and new features to be implemented by the MCU software team.
• As the team scales, there's a potential path to managing a small to mid-size team. The candidate is someone who's excited to grow into a player-coach role over time.
• Work with the teams, e.g., Design, Architecture, Verification, and Applications, to define and implement new security features from design to production.
• Participate in testing and verification of pre-silicon (via FPGA emulation), and post-silicon (first Silicon), and debug of issues found, focusing on Secure Bootrom and Bootloader and the hardware features supporting them.
• Integration and Testing of runtime cryptographic operations utilizing the embedded hardware accelerators.
• Work closely with the SQA and System Test team to help define and implement test cases for security deliverables to ensure full coverage.
• Work with other team members to implement the hardware abstraction layer (HAL) and board support package (BSP) of the SDK.

• BS/MS (EE, CE, or CS) with 10+ years of embedded projects utilizing both bare metal and RTOS systems/real-time environments.
• 3+ years of team management experience preferred
• Expert-level proficiency in C, with C++ and object-oriented extensions.
• Embedded Expertise: Strong knowledge of ARM architectures, RTOS, and low-level drivers (I2C, SPI, UART).
• Security Expertise: Experience with Secure Boot, PKI, encryption (AES, RSA, ECC), and embedded security (TrustZone, CryptoCell).
• Experience: Bachelor's or Master's in CS/EE with 5+ years of relevant embedded security experience.
• Familiarity with debuggers (JTAG, Saleae), Git, and scripting languages (Python, Bash).
• Understanding of security implications for the embedded systems, and familiarity with IoT security concepts (TrustZone, CryptoCell, and secure boot)
• Strong proficiency in Python
• Use of gcc and Arm compilers and MCU IDEs from ARM, Keil, IAR, Eclipse or others
• Excellent problem-solving skills dealing with issues related to HW/SW debug, FPGA/Silicon testing
• Technical Leadership of projects utilizing CI/CD development and automated testing principles.
• Strong documentation skills, mentorship of junior engineers, and ability to work in cross-functional teams.
