  • 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.

Qualifications

  • 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.

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
