Senior Security Architect - Embedded Systems & MCUs

STMicroelectronics in Italy is seeking a Senior Security Architect to lead hardware and software security for next-generation microcontroller products across automotive, industrial, robotics, and general applications.

The role requires deep expertise in security architectures and hands-on work with standards (ISO21434, ISO62443, SESIP). You will collaborate across hardware and software teams to implement robust security features and documentation, supporting audits and PSIRT as needed.

Define security concepts and architectures for microcontroller products. Perform threat analysis and risk assessments (e.g. TARA) to define features and countermeasures. Derive HW/SW security requirements from goals and use cases. Identify security features for protection of assets and functionalities. Ensure coherence of security solutions across the product base. Develop and maintain security documentation. Collaborate with design, verification, firmware, and software teams to implement security requirements. Review architecture against standards and customer requirements. Support security claims in audits and PSIRT activities. Contribute to the roadmap for reusable security IP and guidelines. Degree in Electrical/Computer Engineering, Embedded Systems, or related field. Experience in security architectures for microcontrollers, SoCs, or embedded systems. Knowledge of security mechanisms and cryptographic operations. Hands-on experience with security standards such as ISO21434, ISO62443-4-x and SESIP. Experience in threat analysis. Understanding of microcontroller architecture concepts (CPU/memory protection, access control). Ability to translate system-level security requirements into actionable architectural requirements. Strong documentation and communication skills across hardware and software disciplines.
