Key Responsibilities

Job summary:

We are looking for a high-caliber and motivated Embedded developer with 3–6 years of experience to contribute to the development, integration, and verification of a secure, modular cryptographic framework for Aerospace. This role is ideal for a candidate eager to gain hands-on experience in low-level embedded C/C++ programming, windows kernel security concepts, and aerospace safety/security standards.

Responsibilities:

• 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 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.

Qualifications :

• 3–6 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.)
• Foundational knowledge of networking concepts (TCP/IP) and hands-on experience implementing or integrating MACsec, IPsec, and TLS protocols demonstrated
• Proficient in low-level driver development for communication protocols including Ethernet, CAN, SPI, I2C across various diverse microcontroller/processor families
• Expertise in implementing cybersecurity controls on hardware platforms, including secure boot mechanisms, secure update, secure provisioning, and secure logging etc
• Proven track record integrating commercial crypto libraries (e.g., mbedTLS, wolfSSL, OpenSSL derivatives) and/or developing custom primitives for embedded systems
• Exposure to Windows kernel-mode programming, specifically driver development
• Excellent debugging, and security validation skills for windows and embedded environment
• Proactive learner with the analytical mindset required to develop expertise when navigating unfamiliar technical environments
