Microcontrollers & Digital ICs Group (MDG) contributes to many of ST’s strategic goals for Industrial, Personal Electronics and Communications Equipment. MDG represents about one third of ST’s business.

MDG has around 3,000 employees mainly in R&D teams in France, across 40 countries, with a revenue exceeding 3 billion dollars in 2020. It focuses on two main activities: General Purpose Microcontrollers, Memories and Secure Micro (MMS Subgroup), which accounts for 80% of MDG's business, and Radio Frequency, Digital & Mixed Signals activities (RFC Sub-Group), which accounts for 20%.

The Microcontroller Division (MCD) is the largest division at ST Microelectronics and the world leader in the microcontroller market, supported by our STM32 products. As a leader in the rapidly expanding Internet of Things market, MCD aims to continue innovating in the microcontroller (STM32) sector by developing tomorrow's solutions.

We are seeking a passionate and motivated experienced Embedded Software Security Developer to design and develop security applications on STM32 microcontrollers.

You will join a team in Le Mans responsible for creating embedded applications with security functionalities using STM32 microcontroller security features. Use cases span IoT, industrial, and consumer markets, such as securely managing (installing, updating, isolating) confidential information stored inside STM32 microcontrollers.

Responsibilities:

• Follow security standards and address vulnerabilities in security microcontrollers reported from the field.
• Contribute to STM32 security hardware specifications to enhance robustness of security applications.
• Develop and execute verification (FPGA) and validation (Silicon) security plans.
• Follow the SW development process from specification to validation, developing STM32 security applications to demonstrate and promote security features to end users.
• Support security labs in assessing and certifying STM32 security solutions against ARM PSA or SESIP standards.
• Assist customers in using our security solutions.
• Analyze and fix reported STM32 security software vulnerabilities.

Profile

Required skills include:

• Embedded & Realtime Software Development experience with C/C++ and assembly languages (Debugging, Profiling).
