About the role

  • Lead the evaluation and procurement of off-the-shelf cryptographic libraries from external vendors or chipset suppliers, selecting optimal solutions based on performance, compliance and integration ease.
  • Design and develop custom modular cryptographic components (e.g., AES, SHA-3, ECC or post quantum primitives) adhering to secure coding practices and formal verification and aerospace standards to minimize risks and ensure reusability.
  • Direct integration of selected (or custom-developed) libraries into embedded system through development of standardized peripheral drivers compatible with diverse chip vendors (e.g., ARM, Power PC etc.) and common driver services in a modular framework.
  • Collaborate with hardware, security, and systems teams to prototype integrations, document APIs/frameworks, make design decisions, prepare usage guidelines and recommend production-scale adaptations.
  • Build and test applications leveraging this framework, demonstrating end-to-end hardware security concepts with cryptographic operations like encryption/decryption, digital signature, key management, and authentication in aerospace environments.
  • Implement secure boot processes, including firmware validation, chain-of-trust establishment, and hardware root of trust integration.
  • Conduct verification and validation testing, including unit/integration testing, security audits and performance benchmarking, to verify interoperability and compliance.
  • Conduct security analyses, including side channel attack mitigations (e.g. timing, power analysis) and formal verification of cryptographic implementations.
  • Mentor engineers across embedded development lifecycle, sharing cryptographic best practices, conduct code reviews, and enforce adherence to coding standards e.g., MISRA, CERT guidelines.
  • Monitor emerging updates to libraries, standards and aerospace security threats in order to plan roadmap of the project; contribute to patches when required.
  • Perform and coordinate dedicated risk assessment for cryptographic integrations and overall security concepts to identify, prioritize, and mitigate vulnerabilities, threats and failure modules in embedded environments.

Requirements

  • Bachelor's or Master's degree in Electronics and Communication, Electrical Engineering, Aerospace engineering, Computer Science or a closely related field; advanced degree preferred.
  • 5+ years of experience in embedded software development, with at least 2 years focused on cryptographic integration and development.
  • Deep proficiency in C/C++ for low level embedded programming; including bare metal, real-time operating systems environments (e.g., VxWorks, FreeRTOS).
  • Demonstrated expertise in interfacing with multi-vendor hardware peripheral, such as SPI, I2C, UART, CAN, Ethernet, and cryptographic accelerators on platforms with chipset vendors TI, NXP etc.
  • Proven track record integrating commercial crypto libraries (e.g., mbedTLS, wolfSSL, OpenSSL derivatives) into embedded systems, with successful deployments in secure applications.
  • Experience with implementing cybersecurity controls on hardware platforms e.g., secure boot mechanism including cryptographic firmware signing, secure provisioning, and chain-of-trust validation.
  • In-depth knowledge of security validation frameworks for embedded systems.
  • Excellent analytical and debugging skills, with experience in prototyping development, security validation, and risk assessment in regulated and high-reliability environments.
  • Ability to work collaboratively in cross-functional teams, with strong communication skills for technical documentation and stakeholder briefings.
