Cyber SecurityRTOSTCP/IP

About the role

  • Write, test, and debug high-quality C/C++ code for RTOS (e.g., FreeRTOS) and bare-metal environments.
  • Development of standardized peripheral drivers and Hardware Abstraction Layers (HAL) for diverse chipsets.
  • Integrate commercial and open-source cryptographic libraries (e.g., mbedTLS, wolfSSL) into the embedded framework.
  • Implementation of security protocols like TLS, IPsec, MACsec at the kernel or driver level on both Windows and Embedded targets.
  • Perform unit testing, integration testing, and basic performance benchmarking on cryptographic components.
  • Assist in generating documentation and evidence for security and safety compliance.
  • Implement Secure Boot, Chain-of-Trust, and Hardware Root of Trust (TPM/HSM) integration on embedded targets.
  • Participate in code reviews, focusing on adherence to secure coding standards (MISRA, CERT).
  • Update and maintain technical design documents, test reports, and configuration files.
  • Proactively learn aerospace standards and new cryptographic techniques.
  • Lead the documentation and validation for DO-178C (DAL A/B) and DO-326A/356 certification.

Requirements

  • 2–6 years of professional experience in embedded software development.
  • Strong proficiency in C/C++ for bare-metal, RTOS and Windows Driver environments.
  • Experience with Windows kernel-mode programming (e.g. drivers etc.).
